I own a Computer Battery Analyzer which was recommended by Mooch, a popular and professional lithium-ion battery tester for Vapers. I test all cell batches to confirm that they are indeed genuine.

**If you receive any cells that don't meet capacity spec, send them back and I'll test them. If confirmed I'll reimburse postage fully and resend or refund. That's my guarantee.**
