The Weltool INR26-110 is a high-capacity 3.6V lithium-ion battery, featuring a nominal capacity of 11000 mAh and a rated capacity of 10800 mAh. This full-tab, button-top cell is engineered for high-drain applications, supporting a maximum continuous discharge of 40 A. Recommended charging current for this battery is 5.5 A, with charge and discharge cut-off voltages of 4.2V and 2.5V respectively. This cell retains at least 80% of its capacity after 800 charge cycles. An internal resistance of 7mฮฉ ensures efficient operation across a wide temperature range, from 0 to 45โ for charging and -30 to 60โ for discharging. As an original cell without an additional protection circuit, users must ensure proper charging and discharging practices to prevent over-discharge or over-charge.

Lithium-ion Battery warning: All Li-ion batteries have a risk of fire and/or explosion. Handle batteries with care, ensuring not to overcharge or over discharge, even if the battery contains a protection circuit. If battery is visibly damaged, stop use immediately and dispose of appropriately (Li-ion batteries pose a serious fire risk if thrown into household waste). If a battery is not to be used for over two weeks, store partially charged (30-50%) for maximum capacity retention.
