The battery pack in the Ranger does not want to charge lately. The "fuel" gauge (SOC) shows 3/8. The Distance To Empty shows 25 miles.
I popped the caps off the batteries and connected my 10 amp 12 volt charger to the batteries one at a time. I watched each cell make bubbles. Each battery was connected for a minute or two.
There was some variation in the level of acid. I could see some solids floating in most.
When I was done, SOC 3/8, DTE 25. The few that I checked were about 12.9 V less than an hour after charging.
Is this what's to be expected when letting a set of batteries sit neglected for 3 years?
The pack seemed to come back to life for a while but they're acting worn out now. Is there a file or a link to the basic knowledge I need?
What's the voltage of a fully charged 12V battery in good condition? That kind of thing. Costco has deep cycle battery size 24, 85 Ah for $72.99. They can order 26 with all the same mfr date. Is it time to change the pack again?
