So I've reading that I should "trickle charge" my RV's batteries. But I can not find anything for how to do it!? Can I use my usual charger or do I have to buy yet another unit?
Thanks.

Your RV has a converter that supplies the 13-15 volts needed to charge your batteries. (most likely)

You would have to tell us what MH you have and maybe even what converter in order for us to tell you more.

If you motor home is about 20 years old you probably need a new converter if you are getting new batteries.

Hi Joe! You may need to trickle charge your batteries if you don't use the RV for extended periods of time.

I'm not familiar with a TT. Does it have a converter that charges the batteries when plugged into shore power? If not, OR if you don't keep the RV plugged in, then you may want to buy a small "battery maintainer" or "trickle charger", maybe 1.5 to 4 amps, and leave it connected to the batteries when you are not RV'ing!

If you do this, just be sure to check the water level in the batteries at least once a month and top them off with DISTILLED water when needed!

Good luck, happy trails, and God bless!

The easy way is buy a matter minder for about 30 bucks.

Do not get the big one but just the one amp model is all that is needed.

Disconnect the ground cable at the battery then clip it on and let it be.

Before doing this leave it plugged in overnight with everything turned off but converter running.

Then check water in batteries and add if needed.

Battery Minder, Battery Tender, Yuasa are all battery maintainers that do a good job.

"RVNewbees"......You need to know what type of charger you have in your RV. A good quality charger, typically charges in three stages. The last stage is "Float" charging and will maintain your batteries. If your charger doesn't have a three stage charger, than you should buy one of the chargers listed above, like the "Battery Minder". It comes with a cable that attaches to your battery posts and has a quick connect on the other end. Once home, you can quick connect the charger and leave it running until your next trip.
