(More customer reviews)I usually stay with Canon accessories for my Canon cameras, just for the 'peace of mind' I can expect from the same manufacturer. But in this case, I see no reasons to choose this item (Canon NB4-300 Battery Pack) just because of the brand name. Consider the following facts:
1. Canon is not a battery manufacturer. So those 2500mAh rechargeable NiMH cells are simply re-labeled from other vendors.
2. All 2500mA NiMH cells in the market are plagued by the problem of high self-discharge rate. That is, if you charge up a set of those AA cells and leave them in your camera for a few weeks, they may become completely drained before you can take any pictures.
For the price of this Canon battery pack, you can buy eight of the latest generation LSD (low-self-discharge) cells such as SANYO eneloop, Rayovac Hybrid, or Kodak Pre-Charged.. Even though their stated capacities appear lower at 2000-2100mAh, those cells can hold 80% of their charge for 6 months or longer. So you don't always have to recharge your camera's batteries the night before, and you can keep another set of charged batteries as standby. This makes LSD cells much more suitable for digital camera applications.
Personally, I have retired all of my old-genreation (2500mAh) NiMH cells, and am using only LSD cells in photo equipment now.

This four-pack of NiMH rechargeable AA-size batteries can be used with any digital camera or electronic device that is powered by NiMH AA batteries. They're rated with a 2500mAh capacity and can be recharged approximately 300 times.
