I use a normal charger with a discharging function to run down cells you must do this under supervision so that you don’t over discharge the cells down to 3 volts is low enough. For high output cells internal resistance is key the lower you go the better the performance. Unfortunately good low resistance cells cost money, I have re used salvaged Samsung 20s and 25s cells these make excellent high output cells for standard batteries and of course use the Samsung 50S for the 21700 packs are even better the model p42 items, but all cost money unless you can salvage
@@POLOLOUS3 yes I plan to do a couple of 9ah builds soon, however all the aftermarket kits they are not as good as the originals. For standard duty using good quality salvaged cells they work very well.
Nice informative video. I have battery packs 1.5Ah which work since 2016, discharge charge made by Bülle (PRC). Can I upgrade them when they are dead? Is the battery design uniform for these tools? Thank you.
If they are lithium ion cells you should be able to replace the older lower capacity cells with more modern high capacity versions. I also did just this to a 2010 Bosch 14.4volt drill which was fitted with 1.3ah 18650 cells. I fitted 4 x 2.5ah 18650 from a a scrapped shark vacuum cleaner, and the conversion is ace, very infrequent charging now!
Thanks for the video. I learned a lot.
Have you rebuilt any HO packs? Can premium cells match the originals?
What is something simple to discharge individual cells?

@@ACDodd My 12HO have 40t. I read 50s has much less recharge life in it compared to 40t?
@@POLOLOUS3you are correct you don’t get something for nothing.
@@ACDodd have you tried out/tested those case repair kits yet? Any feedback?

Go to 10 on video 😅

@@ACDodd Thank you. You are legend!
Can the contact clips be replaced?
Only if you replace the board.
