Lifeline batteries (Storage)?

We bought a used 19 Ocean Breeze last year and have a question regarding the Lifeline batteries. The previous owner had the trailer sit for over a year without plugging in. The trailer has a factory solar panel with a set of Lifeline 24 batteries.
I'm concerned the batteries may have been damaged just sitting there. The battery disconnect switch was off or not connected.
When I connect to shore power the panel reads 100% charged, when I disconnect after 30 min the panel reads 80% and 12.2 volts. When dry camped the solar panel charges the batteries to 12.2 volts and only 80% full sun light.
I was expecting 100% and about 13.2 volts, is this right?
I contacted Lifeline but no response from them. What are your experinces with this type of setup?
Thanks for your inputs

1 year without juice not good for battery.

conservatively that's 8-10 month dead.

take the batteries to a GOOD VENDOR

and have them charge/load test using the proper equipment.

OR just use the batteries as they is, and while they still have SOME capacity....

it's possible with partial discharges, followed by immediate FULL ON recharges, they can be resurrected some.

1. don't rely on the solar panels for this, PLUG IN TO SHORE POWER...

2. the wall display is WILDly misleading to the uninformed viewer...

how it works and what is shows and what the limitations are has been carefully covered in many many threads...

without REPEATING all of that, the simple analogy is this...

--swim in a big ocean, that is WARM on the surface (that's the display reading)

--then DIVE 50-100 feet where the water is much much cooler (that's the real charge state)

big ocean is primarily COOL except for a tiny bit of surface water...

so the 100% reading is surface voltage NOT equilibrated battery voltage.

one can check the charge after 1-2 hours (with a small draw like a LITE)

and read the display for a more reliable (still not accurate) voltage...

best o luck and hopefully some1 will come along and post the correct stuff now...

all of the true things that i am about to tell you are shameless lies. l.b.j.

we are here on earth to fart around. don't let anybody tell you any different. k.v.
