These type self-discharge to prevent leaking and overcharging. Also, low tech batt discharge when they are making contact with metal (charging terminals). Try taking them out after fully charging, they will still discharge but not as quick.
Sorry, there was a problem. Please try again later.Mine did that the first charge but has since been fine. The batteries last about 10-15 minutes each now. Do not think your doing anything wrong. Make sure the batteries are cool before charging and don’t over charge is the only advice I can think of. Hope you get it working!
Sorry, there was a problem. Please try again later.I have not had issues with batteries. I do not leave them plugged into charging base after they are done charging. That might cause them to drain if the base is unplugged.
