Why don't RV's have battery trickle chargers when plugged in ?

My FR Lex 265DS does not charge the hotel batteries when plugged in to local power. This caused my slides and auto-levelers to malfunction due to depleted batteries. My boat has a trickle charge that keeps both batteries charged all the time. Can a battery trickle charger be added to the main power system? Why isn't that standard?

Your unit should charge the batteries when plugged in to power that is what the converter does when working right.

A lot of the converters are made in China and a malfunction isn't uncommon.

Make sure your battery disconnect switch is NOT in the disconnect position.

Make Sure your converter is putting out, and tHat house battery switch is turned on.
Also check the model of your converter to make sure it will cycle to a trick charge when batteries are fully charged. Cheap converters don't do this and will run your batteries dry and then burn up your batteries if left on charge all the time.

Most if not all rv's that have a on board power system (storage batteries) have a onboard charger, now it should be said that there is a big difference between a low end charging system and a high end system. That being said most factory installed converters are the low to middle grade models (until you get to high end motorhomes) and if you are going to be spending a good amount of time off grid you will absolutely want to upgrade the converter and battery system the factory installs.

But this is no way means that you coach should not be charging the (house) batteries even to just maintain a basic amount of power to use the slides and the leveling system. So since you did not state the year of your coach/battery no one help with any battery conditions, so you will need to have your battery checked t see if it can in fact hold a charge, and if you battery can indeed hold a charge then have the converter checked for it's operation.

Ju7st to let you know with the factory converters not being the best most owners will have the need to replace them within a five year period for one reason or another, so it is not unusual for that to happen.

Hope some of this helps and Happy Camping

P.S. and yes last yr i had the need to change mine and yes it was upgraded from factory

Howdy fdwarren, I read your post about the battery chargers (which is a function of your converter). Here are some links I always suggest for those new (don't worry we were all new at one point in time) to the RV/motorhome lifestyle that may help. You can read at your own leisure.

Electrical 101:

Basic RV Electricity - RV Information (RV Maintenance)

The function of the converter:

http://rvservices.koa.com/rvinformat...d-amp-draw.asp

General purpose everything electrical. Peruse all the tabs:

RV Electric

Dual power source Suburban water heater (if equipped on yours). This one is probably the most misunderstood thing in a RV for those just starting out.

Suburban's electric switch and much more

Hope it helps, Bobby
