Any issue if we use High amps NiMH battery (2500)with Canon 430EX Flash? Shop person suggested alk cell or 700
Joshy Jose asked:
Shop person was suggesting me , not to use high rated battery (Like 2500 mAH) These high amps battery may fuse the motor inside. (The zooming motor. ) He said I can use 700mAH cells or alkline cells. Please advice me, Im already having 4X2500 and 4X700mAH . Atleast can I use my 2500 as backup? Or not to USE ATALL . Body is Canon 350D and Lens is Sigma 18-200. Thanks . Pl ask me if any more details required.

I’ve been using 1800-2500mAh batteries with my flash for years and I’ve never had any problem. Alkaline batteries die out real quick when the 2500mAh last for days..
Personally I’d use the 2500mAh, but if you’re worried, use the 700mAh and keep the 2500mAh as backup.

If you can use NiMH cells, it shouldn’t matter what capacity they are. The mAH rating is quite different to battery voltage, which is the critical issue for electronic components. Every NiMH cell will have the same voltage, irrespective of its capacity, and the flash will draw the same current to run itself with either 700mAH or 2500mAH as a result. So you can expect roughly three times the useful life with the larger capacity battery.

The flash specs reference rechargables, so using them is ok:
Power Source
Four AA-size Alkaline Batteries (6V)
Four AA-size Ni-MH (4.8V)
Rechargables have a different (lower) voltage and devices must be designed to use them, which this flash is. No matter the capacity, the voltage is unchanged. Even if the capcity was 100,000 mha, it wouldn’t be a problem.
Get the most capacity you can! It won’t hurt anything and you’ll get a lot more pictures.
