Hi all. My testing today went something like this.
In terms of drain when running the fridge from the battery, the first session it drained 12% over 2 hours, the second session it drained another 11% over 3 hours. Is this reasonable or does it suggest some damage? It does have a solar panel always feeding it which probably helped reduce drain later in the day.
I think it may be OK but I’m not sure so hoping you more experienced owners may be able to advise. If the answer is “just f’ing replace the battery”, that’s what I’ll do.
- Charged overnight via EHU
- 07:20 - battery was 100% at 13.8V. I then unplugged the EHU and switched on the fridge to run from the battery.
- 09:20 - battery was 88% at 12.6V. I switched off the fridge to see if the battery maintained its charge.
- 11:50 - battery was still 88% at 12.6V. I switched the fridge on again to run from the battery.
- 14:50 - battery was 77% at 12.5V. I plugged the EHU back in and turned the fridge off.
- 18:50 - battery was back to 100% at 13.8V.
