Filling Batteries

I have one in a 4 battery system where the back two batteries are very hard to get to. The front batteries are okay to service. I put the Pro Fill on the back two batteries only, but I do use the pump to fill the front two batteries anyway. It all works fine for me. I would agree that it is pricey but where there is a need, it is worth the price.

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

Never had a problem with the check valve. The squeeze bulb only needs a few squeezes to get the water flowing IF you hold the water source above the batteries gravity does the rest of the work.

We've used the Pro-Fill system now for years and it works great and is easy to use, highly recommend it.

A lotta to do over nothing. Just another gimmick and expense. How hard is it, really to check the water level in a battery ? It takes so little time and allows you to check for other potential problems in the battery drawers (boxes) or whatever. Things like loose or broken wiring at the battery terminals, corrosion, etc.

Wow....this couldn't be more wrong! I've been using the ProFill system for over 7 years on two different motor homes. Even if your batteries are easy to get to and you can stand right over them and fill them, it's still a messy/nasty job. You have to unscrew each cap, fill each cell checking that you don't under fill or over fill. You ultimately will spill some water which adds to your acid issues and you have to make sure you don't touch any clothing and wash your hands thoroughly when done. The ProFill system doesn't blindly fill the batteries from ten feet away. You're still able to look over your battery bay while conveniently filling the batteries.

One of the biggest causes of battery failure is that people hate to fill their batteries, so they aren't as faithful about doing it.

Not only does the ProFill system take under five minutes from start to finish to water up your batteries perfectly, it also reduces acid build up because of the cap design.

The ProFill system is one of the best products you can buy for an RV. They're expensive, but WELL worth the money.

I have a BWT battery watering system that has been great the past two years.
Nothing against flow-rite but get something as I wish I had done this much sooner.
In hindsight I see this as a safety issue that is resolved in addition to time saved and improved maintenance.

This was me. Taking off the propane cover, battery cover, and if I wanted a close look at the water level I had to remove a propane bottle. Yes I was lazy and I was having to replace batteries every year do to low water and plate corrosion. Since I put on a system, I walk out there, plug in the water bottle and give the hand pump a couple of squeezes, done. I am on my 4th year on same set now.

I did on my last system. The caps and floats were flawless, but about 3 years in I started running into ball valve problems.

Its extravagant but only if you can easily pull the caps and manually fill the batteries and see the levels. My two rear batteries are impossible to see the level so the flow rite system is worth every penny for that application. For that it isn't extravagant, its a necessity.

"jwmll"....If it works for you to move the slide in and out, slide out the tray and unscrew 12-18 caps and carefully fill each one, more power to you. The other 17 posters found it easier to use the ProFill.....you know, that gimmicky gadget!

I have to take mine out manually as they are in a compartment under the slide but then I know that all connection are tight and the proper amount of filling is done, Have hydro caps so only take them out once a yr, and yes I have seen some great messes from those squeeze bottle filler's, wouldn't have them. An afternoon of checking everything and piece of mind when done. And the batteries are still in excellent shape after 10 yrs.
