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.
