Are my GC2's Done
Back in February, DW left the water pump on - and I made the bonehead mistake of draining my water tank before I put the 5er into storage.
The pump ran my two GC2's completely dead before I checked the battery disconnect to insure it was "off".
I took my Vecto 1093, and started the long slow process of slowly recharging them up - and after a couple of days of nothing but 2 amps, I was able to get it to start the charging cycle - and eventually after 3 more days, I was able to get it to completely charge.
I did a desulfation on them, and checked the voltage of them - 12.6 after a 6 hour resting period.
I was just on a trip, dry camping for a week, and as I always do, fully charged the batteries, desulfated them, and off I went.
I normally do the 50%-80% cycle when I dry camp for extended periods and given the national parks limit on generator running, I assumed that I could get close to 80% daily - within a two hour window every night between 5-7pm.
What I found was the Vector would charge at the standard rate of 25 amps - and after 30 minutes begin to taper. Hmmm... Something wasn't right.
Ultimately, what I found was the batteries would recharge to 12.46 volts - but there wasn't enough amperage to drive the water pump after them settling for 2 hours.
I think my GC2's are done.
Have I missed anything? Or, is my supposition correct and I just need to bite the bullet and replace them?
Thanks for your thoughts in advance!
