Battery Not Staying Charged

[lagman]

All,

I had my battery hooked up to a trickle charger for the winter. About a month ago I got the TT out of storage and connected the battery. I noticed today that the charge on my battery was only reading 2 of 4 lights. The TT has been plugged into AC power ever since I got it out of storage. I disconnected the battery and while the TT was plugged into AC, checked the voltage on the positive and negative lines to the TT.. No voltage. I assume since I have a 2013 model that it trickle charges the battery when plugged into AC right? Shouldn't there be voltage on those lines?

Any ideas? Checked the fuse box, everything looks ok, checked the AC outlet the TT is plugged into and it checks out. Only other thing I can think of is that I connected an electric jack (not the type with the wireless remote control).. I assume that wouldn't draw power when not in use right?

Thanks,
Dan

Perhaps one of the engineer types will weight in, but if the converter doesn't see the battery , I think the charger will turn off, so trying to read for voltage while not connected to the battery may not give you any valid results.

While on trickle charge over the winter, did you maintain water levels in The battery cells?

How old is this battery?

You might try putting it back on the trickle charger for a few hours. Be sure to check it every few hours in case a cell is shorted. You don't want to cook it.

Figured it out. I thought I had checked all of the fuses but both of the 40A fuses in the fuse box were blown. Likely happened when I first hooked up the battery this year (I mistakenly swapped positive and negative terminals).

Thanks for the help!

Glad to see you found the solution. Thank goodness for fuses.

One follow up question to this:

Since the fuses were blown, that means it has been sitting for over a month without being charged. When I checked the voltage on the battery it was at about 11.5V.. Is it possible I did any damage to the battery? The battery is only a little over 1 year old.

Thanks,

I would put the battery on a regular charger. It may come back for you.

Check the fluid level in the battery as well. Some converters are not so well regulated and the fluid will evaporate out. After you top off the water, charge it up with an automotive charger before hooking it up again.
