WARNING: Use 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 without a protection circuit is potentially hazardous.

I would recommend this item to a friend.

Batteries are too short.
September 28, 2015
Everything was handled perfectly, however the batteries I ordered turned out to be too short. You were my only hope of finding batteries for my outdoor solar light. What I need is: 1850, 3.7 volt, 600 mAh and you had the closest thing but they still wont work because they are too short.
