Frequently asked questions
Can I use this cell in place of AA batteries?
Only in devices designed for a 3.7 V lithium-ion cell. Standard AA devices expect 1.5 V, and 3.7 V can damage them or create a safety risk, so do not substitute without checking the device specification.
How should I charge a 14500 cell?
Use a charger designed for 14500 Li-ion cells, matching the cell size and chemistry. Do not use a NiMH or alkaline battery charger, as they apply the wrong charging profile for lithium-ion.
