Are rechargeable AA & AAA lithium Ion batteries worth the cost

The rechargeable AA/AAA lithium ion batteries can cost up to 4 times the price of NiMh or NiCd batteries so are they worth the extra cost.
In this video i explain some of the misconception and problems that you may encounter if you purchase they batteries for your devices.

Have you tried the 9v ones? I have and they have fake capacities and buck converters. The capacity given is for the 3.7v lithium cell inside, not the 9v switched output.

I have a couple of PP3 ones - I will investigate to see if there is a boost converter fitted and what size of lithium core battery is installed.

I used to use rechargeable AA & AAA all the time with my old camera - well worth it in my opinion.

Are they nicad/NiMh or these new lithium types?

[@protarget1]

There are loads of fakes batteries on all popular selling sites. The only sure way to tell if they genuine is the weight.

Would these be suitable for the surepet catflap?

[@GrahamHoughton12]

Up until the point that the batteries cut off completely and then the flap would not work!

It puzzles me that lithium ion camera batteries do give a state of charge indication. Having said that, I have a new SmallRig battery that substitutes for the Sony NPFZ100 and it has only been used once so far but I swear it was at 45% charge indicated by the camera yesterday morning when it suddenly dived to a red flashing discharged warning. I’ve recharged it but a fully charged original Sony battery is in the camera just now. I charge it using its own USB C port, not in-camera and I do not have a stand-alone charger for these batteries. I have, until now, charged the original inside the camera using the Sony supplied USB C charging lead.

The difference is that in the 1.5 cells the lithium 3.7v core battery uses a buck converter to achieve the 1.5v out put. The charge status of the 3.7v cell is never monitored. The voltage output just shuts off when the battery management chip in the battery sees the 3.7 v drop to 2.6v

Am moving away from powerbanks & moved to AA/AAA Ni-MH battery & use powerbank with them. Lithium batteries are useless & dangerous compared to NI-MH
