I have a 2000 GEM 2 seater that I purchased a few weeks ago. Just charged it for the second time. The dash was showing something like 45 -50 % battery. I plugged it in and the dash light was blinking green. Checked it after about 4 hours and the light was now blinking yellow. I unplugged it and the light blinked red a few times and then went out. I turned the key on and the digital read out showed 100.
The car had the Delta Q charger replaced in 2014, according to the receipts I got form the owner.
The batteries were replaced in Feb 2021. Trojan 12 volt 30xhs flooded. The algorithm was reset to 13 according to the receipts.
Is this normal behavior ?
