Filling Batteries

Adding 2 oz of mineral oil (3 in 1 oil) to each cell prevents corrosion and decreases the need to add any water for years (depending on ambient temps).

The oil greatly reduces maintenance requirements. But they should be checked a couple times a year regardless. Doesn't hurt to check the converter and alternator too.

I'm looking at the Flow-Rite Pro-Fill battery watering system for my Allegro. From what I have seen they seem to work well. Does anyone have thoughts on these?

They work great. I have 6 batteries and periodically I top them all off with no fuss or bother. The only small issue is the hand pump bulb has a check valve that occasional gives a problem.

Batteries stay clean, no mess, no corrosion, pretty much as advertised.

A lotta to do over nothing. Just another gimmick and expense. How hard is it, really to check the water level in a battery ?

Yeah, right. On ours, checking the first two isn't too bad, but the bedroom slide has to be in to access the batteries.

For the other two:

Remove the negative cable(s)
Remove all cables from the first two.
Remove the first two batteries (at 66 pounds each)
Slide the rear two forward, which can only be done about an inch at at time, until they are fully forward.
Now the vent caps are accessible.
Check and fill as required.
Reverse the above process.

I only do this twice a year to check the SG and check and clean all the connections unless something leads me to believe that there may be a problem.

My last coach was very difficult to service the coach batteries also. best solution for me was to just go with sealed batteries when the time came to replace.

Well, if I add two more batteries (going from 4 to 6) like I want to, it will be a pain to check/fill them. The additional batteries will be mounted over the existing batteries. I think I'll look at this system. Hopefully someone answers who is using it.
