3.7V 4000mAh 18650 Lithium Ion Battery Pack with Long Cycle Life for Emergency Lights and Power Tools
Rechargeable Lithium Ion (Li-ion) cells feature a negative electrode (anode) made from lithium compounds. Lithium's high reactivity and lightweight properties compared to NiMH metal alloys result in superior gravimetric energy densities. These cells maintain performance during 12-month storage without maintenance and offer an expected cycle life exceeding 1000 cycles.
