Lenmar DLC4L Lithium-ion Digital Camera/Camcorder Battery Equivelent to the Canon NB-4L Battery

item is excellent. Delivery took 17 days! That is awful. if you are not in a hurry, great, but otherwise, shipping is awful.

I ordered two of these from Amazon. They arrived on time but only one would take and hold a charge. The defective battery would not charge at all. The Canon charger would simply blink. Amazon quickly sent a new battery for an exchange. The replacement works as expected. Maybe just my bad luck, but I've had better success rates with ultracheap Chinese battery clones (like <$4 a battery) from other dealers like Sterlingtek.

This battery lasts a long time, so far it holds its charge longer than the battery that came with the camera. I am so glad I got this battery, I never miss a picture with it.

For the price you can't go wrong. A fraction of the cost charged by a camera manufacturer.

I purchased two of these on the basis of favorable comments. I have only tried one of them so far, and only one charge cycle.

I charged one fully with the Canon charger and used it in my SD450. It's life seemed much shorter than my 2-year old Eveready battery and the Canon battery. I don't know if this is just this sample, will have to use it more and also the other sample, to see.

If I recall, the instruction does say the battery should be charged and drained fully to get maximum capacity. I'll have to test to see if that's true here, but usually Li-Ion batteries like these do not benefit from such charge/discharge cycles.
