Tenergy Li-Ion 14500 Cylindrical Rechargeable AA size 3.7V 800mAh Review

Average Reviews:

(More customer reviews)The battery worked well after I modified the item that it powered. The protruding + side of the cell is shorter than most AA type cells. The item that I had to modify held the tip away from the contact area witch is not typical, but made me wonder why it did not work the first time I installed it.

WARNING: THIS BATTERY IS NOT MEANT TO BE A DIRECT REPLACEMENT FOR AA ALKALINE/NIMH BATTERIES IN CONSUMER DEVICES. THESE LITHIUM ION BATTERIES OPERATE AT MORE THAN TWICE THE VOLTAGE OF AN ALKALINE BATTERY AND 3 TIMES THE VOLTAGE OF A NIMH CELL AND MAY DAMAGE OR DESTROY YOUR DEVICE. NOTE: Use special caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough 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 with a protection circuit is potentially hazardous
