1A from AAA NI-MH Battery?

Hello BLFs, I’m working on my wooden torch build and I’ve been testing with a booster LED driver circuit. It draws 1000-1100mA from a single (cheap) Powertech 900mAH AAA Battery and the voltage reads around 1 volt on load. That’s a bit over 1C discharge for the battery. Do you guys think this is too much for the AAA Battery? I was thinking of using an Sanyo Eneloop XX 2500mAH battery, which draws almost 2A from the single battery. The reason why I’m using single AA/AAA batteries is because I’m aiming for a small form factor for the flashlight build and also because it’s much easier to find/recharge AA/AAA batteries rather than 10440/14500 li-ion. Though I am probably considering to use 14500/18650 for another flashlight build which uses a Nanjg AK-47A driver. But for this build there isn’t really any option for li-ion.

What do you guys think? 1A too much for an AAA battery?

Not sure if it is too much, but it would certainly be fine for an AA eneloop battery

Not a AAA but something interesting.

There are AA Ni-MH batteries called Elite 2000 that supposedly handle 20 amps constant current draw.

Wow…that sounds crazy. I suppose if you drain them at that much current they wouldn’t last very long for an AA battery.

e09 draws constant 1.7A from eneloop.

constant.

i have 16 of those in series to power up my mag458… pulls close to 11amps on fresh cells… runtime 8 minutes with voltage sag!

1A is no problem for a NiMH AAA battery. Most NiMH batteries can do quite a bit more than a 1C discharge (Tenergy rates their batteries at up to 5C). So I wouldn’t worry about it.
