Trickle chargers

I donít get the opportunity to use my Class A as often as I like, and several times my engine batteries are to low to turn over the engine. I can always jump it, but I rather not keep doing that. Any suggestions on a proper trickle charger for a 2 battery 24 volt system. I appreciate any comments.

You have a 12 volt system, 2 12 volt batteries in parallel.

Any standard 12 volt battery maintainer will work.

At a minimum get a 3 amp trickle charger, walmart sells several for around 35 to 50 dollars.

Start with a charged battery and keep something like this on them.

I don't know what motorhome you have so this will be real general. On my Fleetwood Discovery just being plugged into 110 volts at the house will keep all batteries fully charged.

It would be nice to know make/model/year/chassis/engine/ and more so that we *might* be able to give or suggest, a more accurate answer. Some, not all that many, had chassis battery charging systems when on shore power from the factory but, that system may be defective. But, for the most part, most coaches (in general, diesel versions) did not have chassis battery charging when on shore power.

Sooooo, again, we need more info to aid better in accuracy.

A fully charged battery/s disconnected will hold charge much better , no draw. You can disconnect and just charge occasionally . A good tender or maintainer will do fine . Some cheaper ones over charge, discharge if unplugged or go dead with green light until like all is fine until it fully drains the battery. Battery Tender and Minder are top rated brands for a reason..Noco is newer but gets 1000s of good reviews. One odd thing I have read more than once is Noco chargers putting a lot of radio frequency interference.

If the OP has an older coach (before about 2006 or so?), especially a gas coach, it probably does not have provisions for maintaining the chassis battery when plugged into shore power.

Winnebago started to install Trik-L-Start on their Journey DPs, for instance, starting with their 2007 models. I'm not sure what they're currently using but I remember that the 2006 models did not have them and the 2007 did.

To Pop Pop 57, welcome to the forum. As has been said, please give us your coach manufacturer, model year, and chassis information. If you do have an older Class A, there may not be any provision to charge the chassis battery/batteries when plugged into shore power. It sounds as if you do not have this provision.

I like the LSL maintainers (Trik-L-START and AMP-L-START) so you may want to look into installing one or something similar. That way, you won't have to have the hassle of using a separate maintainer on the chassis batteries. I've used them in several applications and they've been flawless.

TRIK-L-START

AMP-L-START

They function the same but one is 10 amp and the other is 15 amp. Trik-L-start used to be 5 amp but I see they upgraded it to 10 amp so it should be more than adequate for most applications now.

I was always under the impression that Winne and Itasca started installing the Trik-L-Start units on the 2006 and above. If I can link it correctly, I have a pdf file that states just that and it's from Winnebago's Service bulletins.

We were looking at Meridians/Journeys at the time and the early 2006s didn't have it but the tail end of the production cycle they may have started installing them. All the 2007 Meridians/Journeys had them. Their gas Class As didn't have them until much later, however ...not sure when.

Unhappy Dead batteries

I bought new 2021 Entegra Vision in November 2020. The last time I used MH was Jan 1. I went out to storage facility yesterday (no electric power at facility).
Both chassis and house battery dead. I expected chassis battery might be dead, but thought I'd be able to start it with house battery. I had cut all power from house by using the "disconnect".
What should I do first?
And with no power at storage facility, what should I do long-term to care for batteries?

Several good option available. I like the NOCO chargers. I have a 10a unit on my chassis batteries (two Group 31 12v in parallel).
