VC2 not charging AA's

[Bravepills]

It won't charge AA Energizer Accu Recharge Power Plus. Just says 'null'.

Charged them on a dumb charger and they seem to have charged fine, measuring 1.4v.

Put back in VC2, still not recognised. Any ideas? I'd rather not use the dumb charger if possible.

Thanks.

Hi there, for your AA Energizer Accu Recharge Power Plus, it needs to use chargers designed for NiMH batteries. And the XTAR VC2 charger charges different popular Li-ion batteries (10400-21700), but can't charge NiMh batteries. If you are looking for a charger that can do both, take a look at VC2S, VC4S.

Ok thanks. Thought it was supposed to charge NiMh but only used for 18650's.

Thanks again, a new charger for me I guess

Even though some newer LiIon chargers may support NiMH chemistries, their NiMH charging strategies are not as good as those of native NiMH chargers such as the Maha PowerEx C9000/Pro. Your VC2 is considered an older model circa 2014 and like the VP2, it's not NiMH compatible -- even though it's a good basic LiIon charger that does its job well (I still have one). I also once owned a VC2+ (Plus) which supports NiMH charging but such charging strategy is not that great: the batteries top off at just 1.45V.

As far as NiMH charging is concerned, consider investing on a better charger to replace the "dumb" one, which would in the long term overcharge all your batteries and thus resulting in very high internal resistances to the point that the batteries will have be junked.

Does the pricey Maha measure internal resistance?
I have been using MiBoxer C4-12, charges all my NiMH to 1.5v settles down to 1.48v
Intelligent, it also supports Li-ion batt chemistries IMR/INR/ICR batt sizes up to 26650
Plus it has an easy to read LCD display is on topside.
Not to mention C-4-12 is half the price of Maha C9000 Pro

The C9000/Pro takes internal resistance into consideration, but doesn't explicitly measure it and display a value on the display.
Nevertheless the C9000/Pro are more established products than many generic Chinese-branded multifunction chargers esp. those with status displays, and knowing that they can last for at least some 5-7 years (or more) I won't mind paying a premium for them.

As for this "MiBoxer" product it actually exists in C4 and C4-12 variants, both with different designs and such. It may provide good price performance to some, but I wouldn't take any risks on it. Same thing goes to Liitokala chargers which look good on the outside but not so good on the inside when it comes to performance (eg. poor internal resistance measurement, per HKJ).
