Just De-winterized the trailer yesterday, hooked up the battery that I keep in the house basement from winter storage. Noticed lights in TT didn't work. So far I have the trailer plugged in charging for almost a day. Put the trailer back on batter power only, noticed lights still not at full power.

Disconnected battery again, have 12.5 VDC at battery and 13.75 VDC on wire leads from trailer. So it seems the trailer is trying to charge the battery. I think the battery is 4 yrs old, how much more time should I wait before I spend $$$ on new one

Thanks for your replies
Mike

You should have kept the battery fully charged all winter, now it may be spent. Charge it some more and then take it to a place like the chain auto parts stores to have it tested.

IMO your battery is toast. Keeping it charged is the key...not storing in the basement. A fully charged battery won’t freeze or we’d all be dead.

Make sure you really clean the battery cables and posts... They may look clean.. But, give them a good wire brush clean and try again.

Good luck! Mitch

couple more things you need to do, all great advice above. buy a battery tender ,for when tt when just sitting . theres always a little battery use when the tt is just sitting in the drive. and always check the water every three months.

I do clean the posts, but now that I think of it the positive lead wire was rusted, I will cut back the wire. Battery had plenty of water.

Thanks everyone

Also you can try a real charger. Something like a garage will use. Sometimes you need to rock the batteries world.

I think 13.75 volts is too low to revive an unhappy battery.
I have a Black & Decker smart charger that automatically goes up to 16 volts when needed. It also has a desulphate mode. It works very well!

I used to keep the batteries in the house but they got too heavy. I live in northern Alberta. Now I leave them in the motorhome and disconnect the batteries when not using them for more than a day unless the solar panel is keeping them fully charged. They stay over 12.6 V for at least a month. I’ve had poor results with trickle chargers.

Something is strange. Baytery might be toast but your converter and the battery at 12.5v should fully power the lights. Fix the bad terminal first.
Also unhook the battery and see if it maintains voltage for a day or so.
Have battery tested.
And you can try charging it again with something that puts higher voltage to it if your converter is only charging at 13.7.

Test the batteries.. I have my own tester but you can get 'em tested at ye old auto store.

Make sure you did not flip the disconnect switch to OFF.
