How to choose rechargeable batteries for my Nikon superzoom camera?

Question

I have a Nikon Coolpix L120 and looking for rechargeable batteries. The Nikon brand batteries have received only mediocre reviews.

What is important when looking for rechargeable batteries to ensure that

1. they are decent and
2. they will be compatible with the camera.

Is it important to ensure the mAH of the batteries are compatible with the camera or does it really matter what the mAH is as long as they are the correct type (AA)?

Answer

There are three aspects to batteries:

• The size (AA, AAA, etc.)
• The chemical composition of the battery (Ni-Mh, Ni-Cd,Alkaline, etc)
• The rated capacity (measured in mAh)

Your device will only specify the size of the battery it needs (in this case AA). Technically you can use any AA battery (rechargeable or other wise) and it would work just fine. But based on the type of device, you can find the best match for your use.

For cameras you need the batteries to last long and be able to provide quick bursts of power to support the flash. Ni-MH (Nickel Metal Hydride) batteries work best. The higher the capacity (mAh), the more photos you can take on one charge. Sanyo Eneloops seem to be recommended by most pros. 2500 mAh and above should last pretty long.
