I have two Ampere Time 12V 190Ah, 2432Wh Lithium LiFePO4 Batteries
I have a dedicated LiFePO4 battery charger that successfully charged both batteries in the past, but now this battery is not accepting a charge any longer
Now when connecting the battery charger to this battery, 14.57 Volts is measured but NO amps.
After disconnecting the battery charger, the battery voltage quickly drops down to 12.34 Volts and stays there
LiFePO4 battery charger info:
Model: Progressive Dynamics, Inc. Inteli-Power 9100 Model PD9160AL
Input: 105-130 VAC 60 Hz
1000 Watts
Output: 14.4 VDC, 60 Amps
Inverter info:
3,000 watt Samlex 12 volt Inverter
For troubleshooting, I have checked and done the following:
1. Tried to discharge the battery with the inverter connected to a load for 30 minutes.
Before connecting the inverter, the battery at rest voltage is 12.34 Volts.
When connecting the inverter to the battery then turning the inverter on, the inverter made a beep noise but then quickly turned off.
The voltage of the battery with the inverter connected was only 5.8 Volts and slowly decreasing.
After 30 minutes of only the inverter connected to the battery, switch on but the inverter does not turn on, the battery voltage went down to 4.96 Volts.
2. Tried to recharge battery after step 1 above but the battery still does not accept any charge
Any other troubleshooting I can try?
P.S. I could return the battery to Ampere Time / Li Time for a refund as it is still under warranty but I live in the Dominican Republic and do only accept returns form the USA. It would cost too much for me to ship to them.
