This product listing offers genuine XTAR 18650 3600mAh 10A 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 3600mAh (12960mWh) of power with a 3.6V nominal voltage and a 4.2V charging cut-off. It supports a stable 10A constant voltage continuous discharge current, making it the ultimate power source for high-performance tactical flashlights, and drones. Featuring a built-in high-strength dual-stainless steel protection board, it effectively prevents overcharging, over-discharging, and overcurrent. Remarkably, it maintains a capacity loss of less than 20% even after 500 recharge cycles. The button-top design ensures perfect contact with mainstream devices. Whether you need a spare or a bulk supply, choose the pack size that suits your needs.

After trying many brands, XTAR's 3600mAh stands out. True capacity, strong button top, and reliable protection. I now have 12 of these.
The 10A CDR is accurate. I've pushed them at 9A continuous and they barely get warm. The 500-cycle rating gives confidence.
These fit my Zebralight, Fenix, and Armytek without any spring compression issues. The 3600mAh gives me peace of mind on long night hikes.
I use two of these in my dual-battery mod. After 6 months of daily charging, they still hold a full charge and discharge evenly.
I ordered the 4-pack and all four tested between 3560-3590mAh. The protected circuit engages smoothly. XTAR's quality control is impressive.
