Ego 56v dead battery fix
Вставка
- Опубліковано 21 чер 2019
- If you have any ego 56 volt batteries that are dead or not taking a charge it's most probably because one or few of the 18 650 batteries inside might have undercharged. They either are going to show 0.00 volts or less than 3.0 volts, which is their minimum voltage. To charge or complete their functions their minimum charge is 3.0 and Max full charge would be at 4.2. I connected a working 56v Ego battery in parallel to the other non-working batteries to give the cells inside a jump start high enough to be able to connect to their charger.

Good advice but it would have been more helpful if you showed us HOW you did it.
Fixed! I did the 6 inch drop onto concrete and put the battery on the charger and amazingly it started charging. I too had the fully discharged red light on battery and it wouldn’t charge on the charger. I called ego support and it was out of warranty. Was considering the jump start thing but last ditch tried the drop and it worked. Totally stoked!
So put your hand on something hot and makes sure it doesn't blow up with your hand on it. GOT IT.
Just tried this method by connecting a fully charged battery to the dead battery. Waited about 30 seconds and it worked! Thank you so much for the information.
Wow, I'm impressed.
Don't tell us how to do it, show it!
Exactly. What did the author do to fix the problem? Show the process. Don’t talk about it. That’s useless for the viewer
Wow this actually worked, thank you!!
For those asking how to wire it, just take regular 14/2 nmd90 electrical wire and touch the positive of the dead battery to the positive of the charged battery and do the same for the negatives. The back of the ego battery has 4 slots, just use the left and right most slots. Disregard the middle slots. Touching these contacts at the same time shocked the battery back to life.
Thanks again!
I don't have a good battery could I use a 12v car battery charger to jump start it
Not sure if it will work seeing as how the ego battery is 56v, but it probably will not damage the battery. You don’t have to leave them connected for long. Just a few seconds jumped mine back to life.
You just saved me the $250 for a new 5Ah battery. Worked fine last season, then sat on the charger for a few months and suddenly, the charger wouldn't recognize it. I thought the charger failed. Gave up and bought the smaller battery locally, the 2.5ah one. Plug the new battery into the old charger and it worked fine. So now its a battery problem. Mine had 7volts across the terminals but wouldn't charge. I gave it a jump start with the new battery and boom, it started charging. Took a full charge and range seems normal. Big thank you!
Worked like a charm. Just connected + to + and - to -. Counted to 30, placed on charger... bingo. Thanks for the tip.
Did you need to open it up or were you able to leave the case on?
Good tip, thanks for making a video. It seems the trick is to NEVER let the Ego battery completely die. Always put it on the charger when there's some life left in it. The internal BMS should prevent this but who knows how well that design is.
Glad I found your video, "jump start" did the trick for me.
Good to hear, glad this info helped you
So just how do I jumpstart please
Had a 2.0 for 8 years, stopped working 5 years ago. Watched this video and I am standing in my garage watching it charge on the normal charger.
Good tip but use resistors as jumpers next time to slow down the charge. The batteries got hot because putting them in parallel like that dumps TONS of current into the dead battery. Possibly 20 amps or more! That will shorten its life significantly. To bring old lithium batteries back to life it’s best to charge them slowly by limiting the current. A pair of 100ohm 25w resistors would be my choice.
is this a general concept for all lithium batteries or these particular 56 V? I have a generic Milwaukee 18 V that I think is too low and won't charge
@@roninwar9846 it's the same for all lithium batteries. They have low internal resistance so charged batteries output high current and dead batteries readily accept it, whether or not they are able to actually charge up. This is different from low lead acid batteries, which sort of self-regulate the incoming current.
In your case, this method probably won't work. 1) because the M18 packs have MOSFETs that turn off charging outside of the charger (they allow power out but not in) and 2) because in the dozen M18 batteries I've been inside, they usually have a single cell (or parallel cell group) out of the 5 total that is low, rather than the whole pack being low. Your best bet is to open the pack and try to 'balance charge' by slowly charging each cell/cell group individually to an even level, like 4v. Then with the pack balanced, put it back on the charger to let the charger determine the final charge level. Lots of videos on balance charging, make sure you watch closely and read up on the subject before attempting it.
would you use one resistor each, one for + to + and one for - to -?
@@marcxgajeton yes I would just so that any heat is split among two resistors rather than one.
It's too bad the ego charger doesn't offer fast & slow modes for charging. I don't want them to charge fast like they do, I rather it charge slower and extend the life.
Thanks so much for the idea to "jump" the battery. I got a "defective" 7.5ah battery that wouldn't charge and got it charging/working with your idea. I had to cut a few thin pieces of metal (cut up a hose clamp with tin snips) for the contacts, VERY CAREFULLY inserted them, being careful not to contact/bridge them together, used a pair of car battery jumper cables, hooked the batteries together for 30 seconds and then quickly put the "defective" battery on the charger and got it to take a charge. I tried putting it on the charger previously 20 or so times and got the red "defective" light. Defective battery was only showing about 30 volts according to my multimeter. Good battery was about 55v.
car jumper cables? you need that thickness gauge? really?
I don’t believe that is necessary, that is just what I had within reach when I did this. The internal battery wiring I think is around 14-16ga. I wouldn’t go too thin or it might melt/burn insulation.
@@talon146 ok jumper cables and some cut up hose clamps it is- will see later today
This process also works for 20v batteries. The charge is pretty much instantaneous, gets the battery pack juiced enough to work on the chargers.
Possible method to reset battery pack
I pressed and held the battery button while placing it on the fast charger, continuing to hold the battery button for several seconds after putting it on the charger. THIS WORKED!!
Thanks this seems to be working for me too.
You could also just throw a 12V trickle charger on them for an hour or five to get them up from zero and then use the normal charger. I have some 20V Black & Decker batteries that were completely dead and revived by throwing a 5V charge on them for a couple hours Using an old cell phone charger. Once it has some power, the smart chargers will recognize the battery and do their thing.
Thanks for your video and the info
I have a 56v battery could I use a 12v car battery to jump start it?
Show us how to jump them next time
Yay I jumped my two 2.5ah batteries using a cut up hose clamp for 20 seconds and now it's charging.
It won't charge it all the way though. I opened the battery and found one of the small wires going to the battery was not soldered on. It's charging now
I'm also using the 2.5 56v On my razor scooter. I got a 800w 36v motor and controller. It's been handling it with no problem at all. I gotta used ego 56v 2.5 . it Don't light up when you push the fuel button Or when you put it on the charger don't show any charge. It does have 53.3 volts now. Do ya have any idea why It's not charging or what I can try?
Congratulations you fixed it! But maybe show how you did fixed it 🤔
So...put your hand over a battery that may be about to explode? Something about this advice seems off to me.
Depleted batteries won't explode....
Is that motor still holding up at that voltage? Did you have to use a different speed controller or did the stock board take the 56v?
Its still working and I bought another 650 for my older son and they take the higher voltage no problem.
Trying this now on a 7.5ah ......charger says is full but at 54v.
Using a 2.5ah battery that isn't full and at 57v.
Initially 3.4a flowed and after 30 seconds I'm down to 1.7a.
Not much current.....under 200w.
I am having a problem with charging. The chargers green light blinks twice and intermittent off and on. The battery blinks green three times intermittent off and on. I am just wondering if the charger is completely bad or if the battery is so low that it won't charge.
Hold your hand on the battery cell just before it blows up.. YIKES
Just did this, for not even 15 seconds, and it jump started the battery just enough for it to start charging again! See how long it lasts…
Hi, can you tell me what orientation is D12 diod an charger EGO 56 v, anod toward's screw? mine burn out ,and i dont now witch side i have to solder?
How did you make the jumper cable?
Just terminate two wires with male or spade terminals on both ends.
Mine wasn't charging.. no fan, etc.. Read about dropping the pack on the floor... SO I hit/tapped it with a rubber mallet on all sides several times and it is now charging away.
Guessing the battery contacts somehow get a buildup and lose contact....
Same problem my battery was 1 month outside of warranty - EGO response TOUGH so no more buying of their products.
Dropping it worked! Red lights when I pressed button and would not start charging. Tried holding the button for ~30 seconds while on charger and nothing. Just got some hose clamps cut up and on the way to car for jumper cables (Figured I'd be around the corner to make connection in case anything blew up 8-). On the way, I tried dropping the battery on garage floor from about 6 inches, once. I put it on charger and it charged. Put it on my trimmer and it runs so I'll make sure never to let it get to zero again. Thank you.
My first battery died after four years. Had heard about the dropping it on the floor trick so I did this and it worked, giving me another year before it died completely. I always put it back in the charger after use. Five years from a battery used on two devices regularly isn't bad in my view.
Just dropped my battery and it started charging! Genius!
Wow. My 3-year-old 7.5 amp died suddenly. Dropped it a couple of times from 6 inches...and now it's working just fine!
So what did you do exactly?
My problem is a bit odder. I have a 7.5ah battery where the cells all seem to be ok. The problem is charging.
I get a full run on the battery in my EGO mower. When the battery is down, I put it on the high (or low) speed charger. The fan hums, the green light flashes, and then in 30 seconds or so the charger shows the batter fully charged. It obviously hasn't charged. The voltage reads around 46v. No matter how long I wait, unplug everything, etc., this won't change.
From some other electrical experience, I tried putting the battery in the fridge or freezer for a few hours. Then I put it on the charger and all worked normally. Got the battery up to full voltage and could do a normal run with the lawn mower. This has worked several times, telling me the battery cells are likely ok. It's something else in the battery circuitry.
EGO does not repair batteries, even if the cells are ok. I'm wondering if anyone else has seen this or has any suggestions.
I have a 7.5 amp hour battery that I got with my 21 inch push mower. Just over two months of owning it, the battery whether it's fully charged halfway or whatever will completely die when using the mower. All five of the LED lights on the battery will turn Red. They will be solid red for about 5 to 10 seconds and then shut off. At that point if I put it on the charger even though there's plenty of charge, they will still show up all red. Now, if I wait 20 minutes and then charge or start using the battery in my mower I'll have about 15 minutes of run time and then the LED lights will turn all red again.The battery was under warranty. So I'm waiting for my new battery to be shipped to me. It's been almost a month and still no battery. What a joke.
I actually just had this exact issue with my 5.0 blower battery. Ego did replace the battery fairly quickly, so you might want to call them again.
My 5.0 has dropped to 3 volt and won't charge today. 2017 model
Video could be improved by showing how to connect the batteries.
Honestly, if you can't figure out how to connect + to + and - to -, you shouldn't do this.
@@jonathanridder I think a visual would be helpful, but I guess it means just jump from one sealed battery to another using thick cables and flat metal in the + & - tabs
How long did the batteries need to be connected to each other to get enough charge for the battery charger to work?
Same question. I have a good 7.5 Ah jumping a “dead” 2.0Ah and the 2.0 has no lights at all and even when I’m jumping it I am getting the 2.0 to have a flickering red light when I push its status button while being jumped from the good 7.5Ah. However if I unplug the jumper cables the 2.0 status button does nothing anymore and nothing happens when I put it on the EGO charger. So I am wondering how long do I need to jump start it with the 7.5Ah for it to work on the regular charger on its own???
@@alexmasi9453 , when I tried this on my batteries, it was about 10 min, but I took a break because the batteries did get quite warm at one point. It's definitely good to keep a (gloved) hand on the batteries to make sure they don't overheat. This trick totally saved my 7.5 Ah battery, but couldn't revive a smaller one that had been discharged longer.
Ego if you watching this your brand really sucks I waist my money buy the leaf blower and there a problem with the battery it keep blinking red light leaf blower only works ten sec
What if my Ego charger(I have 2 of them)f/the "56 v blower" only holds SEVEN MINUTES of charge? That's for both batteries(I own a 2nd one as a backup)-and I have a card attached to the blower which says "75 minutes" of charging time or lasting power that the batteries are supposed to have, when fully charged; this has never been true, since I first owned the blower, w/the batteries, back in May of 2019. Why didn't I get a refund? Because I supposed I was so busy at the time, coupled with the fact that there just aren't any good blowers for a comparable price, that were available.
I mean the blower does the job, it just doesn't hold the charge it is claimed to hold-not for even eight-but seven-minutes(yes I timed it repeatedly over the last 2 1/2 years since I first purchased the blower with both batteries-and the extra battery cost me $150.00(at Home Depot); I feel like I've been took but I've had the blower for too long to return it(and yes I tried to contact Ego at their headquarters, within the 1st two weeks of purchasing this blower and battery-by phone, and online as well as by mail-sent them a letter detailing the problems I was having w/the batteries-but I never, ever heard from, or got a reply, back from them)-perhaps someone who sees this can help me with my situation or problem.
P.S: Was watching a UA-cam video which stated the battery, when fully charged is supposed to hold no less than FOURTEEN MINUTES OF CHARGE-what then, again, for both of the batteries I've had-and used-consistently-for the last two and a half years?

You have to register your batteries (tools too) on their website. Then call them with your issue. Then they're going to waste a whole bunch of time troubleshooting the issue before they send you a replacement battery under warranty. I've done this twice now, both times successfully.
I'm extremely disappointed in this brand.
This is my 2nd summer using 56v 5.0AH EGO batteries and they just won't hold a charge.
This is on the 5 blinking light battery:
1. Place battery on charger
2. Starts charging
3. No more than 10 minutes later, stops charging.
4. Take battery off charger, check charge level - it hadn't even charged 1 extra bar.
5. Place battery back on charger - begins charging.
6. No more than 10 minutes later, stops charging.
Basically I need to babysit the battery/charger in order to get it to continue charging.
I've tried two different chargers and 2 different batteries - they both do the same thing. Very poorly made expensive products.
There's a warranty on these expensive things - so I'm definitely using it.
I don't have a good battery could I use a car battery charger to jump start it
So, I have a good 7.5 Ah jumping a “dead” 2.0Ah and the 2.0 has no lights at all and even when I’m jumping it I am getting the 2.0 to have a flickering red light when I push its status button while being jumped from the good 7.5Ah. However if I unplug the jumper cables the 2.0 status button does nothing anymore and nothing happens when I put it on the EGO charger. So I am wondering how long do I need to jump start it with the 7.5Ah for it to work on the regular charger on its own???
The "jump" should only need to be in place for a 30 - 60 seconds.. really. If the BMS isn't lighting up, you may have a blown fuse inside the battery. Pop the case open, swap the $0.75 fuse, close it back up, see if it'll charge.
I’m sorry, did you say make sure to put your hand on them to make sure they don’t blow up? Lmao. 😂
Hey can I send u my 3 batteries to fix?
Did you connect positive to negative or positive to positive? I'm new
Yes, but add a resistor, which is something he didn't do. Anything is better than nothing. You can even use a steel clothes hangar as a resistor.
@@ronaldroberts7221 do you still need the resister when using a car jumper cables? I feel the thickness of the cables might help with the resistance like a coat hanger
@@manborn The thickness of copper wire does not increase resistance, but the length of cable is what adds resistance, the longer it gets, the worse the resistance. You could use a long house-outlet extension cord for equalization, that would have plenty of resistance to slow the equalization...
Yes is not an answer to this question
@@chrisyahvah8681 lmao. Thanks. I was wondering too.
Didn’t show anything worthwhile. Why was this video made?
Okay so put my hand on the possible explosive 🧨 ✅ makes sense 😀🤣
New cost $249.00
I just throw my batteries at a concrete wall as hard as possible
I had two batteries... one went bad after one year... bought a new one... then one of the chargers went bad... now my second battery charger went bad... this product has great power, but the charging stinks...
Great video… that explained a whole lotta nothing
Ego makes pure garbage batteries and they don’t warranty for shit!! I would avoid them like the plague!!
Yeah, when I did this you couldn't get 56v battery packs on amazon or ebay. Since there are ebikes and scooters everywhere, it's cheaper and easier to go that route.
DO NOT DO THIS-you will kill both batteries or more.
