NiMH AA(A) charger recommendation

Hi,

I’ve been browsing a few threads from a few years ago and came across many different recommendations, but most threads mentioned the Panasonic chargers from the Eneloop bundles (BQ-CC55 or BQ-CC16). Are these still the best value chargers out-there nowadays?

I just need to charge AA(A) NiMH as fast as possible while keeping them as healthy as possible.

Thanks!

For small AA and AAA Ni-MH batteries charger, maybe you can take a look at this BC4 charger: independent four-slot, compatible with AA and AAA Ni-MH batteries, also 1.5V Li-ion batteries.

If you have a lot of NiMH batteries, its hard to beat the Maha Powerex

Is that ALL you want to charge? What about other chemistries?
Do you have a mess of them to charge at one time, such that an 8-bay charger is worth the extra?

Having capacity testing is a very nice feature, and worth the small amount of extra money.

That’s all I want to charge, and 4 bays should be enough. If the difference in price is minimal, having more features, supporting other batteries, or having more bays would always be nice. Smile

What is the fastest speed to safely charge a NiMH without damaging it too much? As long as the charger detects -dV/dt termination, I should be able to charge at 1A per battery, right?

I think 1A for AA NiMh seems OK, but may still be a bit too fast for AAA NiMh… also may depend on the battery’s age/condition. (older / higher resistance NiMh probably should be charged slower… although I think some chargers automatically adjust the charge current if detecting a higher-resistance battery)

I tend to generally charge AA @ 500-700. 1A is OK but a bit harder on the battery.
For AAA I use 200-300, and don’t exceed 500.

HKJ has a table of tested chargers with a great sorting mechanism. Here’s a link;

Go the [Extras] column, click on it, scroll down to a section with [analyzing chargers] and whatever else you want, plus at least 2 smiley faces, and start doing some research.
Don’t forget to look at the current capability.
