This listing offers authentic XTAR 18650 3500mAh 10A high-drain lithium-ion rechargeable batteries (available in flexible pack sizes of 1, 2, 3, 4, 5, or 10 batteries). Engineered with a strict commitment to "True Capacity, No False Labeling," this battery delivers a genuine 3500mAh (12600mWh) of power with a 3.6V nominal voltage and a 4.2V charging cut-off. It supports a stable 10A continuous discharge current, making it the ultimate power source for high-performance tactical flashlights and moderate-power electronic cigarettes. Featuring a built-in high-strength dual-stainless steel protection board, it effectively prevents overcharging, over-discharging, and overcurrent damage. Remarkably, it maintains a capacity loss of less than 20% even after 300 recharge cycles. The button-top design ensures perfect electrical contact with mainstream high-drain devices. Whether you need a spare or a bulk supply, choose the pack size that suits your needs.

If you need reliable 3500mAh button tops, these XTARs are the benchmark. I've tried cheaper cells and they don't compare.
These cost a bit more than generic cells, but the consistency and protection are worth it. All my high-performance lights use these now.
The protection circuit has saved me twice when I left my flashlight on. The cell simply cut off at 2.5V and recharged fine.
My night vision monocular runs 12+ hours on one of these. The 3500mAh rating is legit. I've ordered the 10-pack.
I use four of these in a 4S light. They balance perfectly and the protected circuit prevents over-discharge on long runs.
