Use special caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. We recommend you have a knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. We are not responsible for damage if there is any modification of the batteries/chargers in any form or shape (including pack making). We are not responsible for any damage caused by misuse or mishandling of Li-Ion batteries and chargers. We only recommend using Lithium Ion rechargeable batteries with a control circuit (protection PCB) to assure safe charge, discharge, etc, use of lithium ion batteries without a protection circuit is potentially hazardous.

I would recommend this item to a friend.

Great replacement for OEM product
November 18, 2014
The battery pack for my DSLR died. I disassembled it, bought these cells and replaced them one for one, and they charged/perform as good as new. Saved me about $50! Thanks, Battery Junction for your quick service.
Reasonable price, same size as OEM cells, same mW rating.
Not much: needed to modify the tabs a little.

better than expected

For less than 4 bucks I didn\'t expect much, but these cells are legit in their claims. Have them in several flashlight mods and they are at least 2C discharge for sure.
