HI Guy's

Well winter is almost here. I took out the batteries last weekend and hooked them up to my (expensive but 6 year old) xentrax true charge 10. However when I hooked up the batteries, nothing happened, my charger is dead.

So I have to look for a new charger now and I wondering what everybody else is doing. Leaving the batteries inside the coach is not a option. it gets below 0 degree here and I lost a set of batteries last winter.

So what do you do?
How do you store your batteries?
What kind of charger do you use?

Get a Battery Tender. I have never taken the batteries out. If you do take them out don't leave them sitting on a cold concrete floor.

I bring my batteries into the basement and charge them once a month and try and do it around the first week of the month not that it matters its just that way i remember to charge them. Have been doing that for almost 20 years with different campers and batteries. I have an old sears 10amp charger that has been around for years also.

I do exactly the same thing (maybe not the first week of every month). Before the motorhome, the same practice was used for 25+ years with my sailboat batteries.

Even I can lean something. Done the search but to many******hits and I got tired of reading all the post and not finding the answer I wanted.

If everything is answered and everybody uses the search feature we would no longer need the forum

And if it is bugging you that I asked the question, why did you answer?

I would be tempted to run a equalizing charge on them just to bring them up to snuff. Then a float charge for the duration. I'd also be tempted to run another equalization before using them in spring too.

Note Trojan says charged batteries freeze at around MINUS 90 degrees F. If only 0 degrees or so killed yours, you didn't keep them charged.

I keep mine charged, rather than carrying around heavy acid filled containers. The batteries in our RV are kept charged with a 15 watt solar panel. Other batteries are kept charged with various methods. I'm sure not bringing nine batteries from various vehicles inside every winter, but your choice.

BatteryMINDers sure work nice.

Did not have trojans. Batteries were 4 year old Interstate. Probbably porly charged. Mu 120w solar got covered by snow. By the time I check stuff out it was too late and the batteries were history. YES MU MISTAKE.

It can easily get to below -25F out here. And I will not even keep my new T-105 out at that. Since they run at $200 canadian per piece.

I take mine out. The go on a piece of 3/4" plywood on the floor of my heated garage. I'm not as good as I should be about keeping them charged. My boat batteries been down there untouched for 2 years, they came right up when I put the charger on them a couple weeks ago.

Battery tenders are good.

Cold along with non-use will kill a battery over a winter.

Overcharging is bad too.
