Twenty Li-ion batteries pulled from an Anker power station that wouldn't start up, appears fine otherwise. Would love them not to go to waste, sadly I don't have time to make something with them.
They are labeled ITR26/70-40E 3.2v 12.8Wh
TESTING PROCESS:
They are labeled ITR26/70-40E 3.2v 12.8Wh
TESTING PROCESS:
- Measure cell original voltage
- Recharge using XTAR VX2 PRO Battery Analyzer / Charger
- Record final voltage
- Wait 2 weeks minimum
- Measure again, calculate voltage drop (data below)
- Set into "Store" mode on XTAR VX2 Pro to preserve cell life
