Hello,

A couple of months ago I topped up our 3 110ah lead acid batteries. I had not done it for a while and each battery took at least 3/4 litre. Today I checked them and two of them were very low (there are two of one Brand one of another). I have put 1.5 litres Distilled water in the two of the same brand but they need more!.

Seems a lot to me. What do we think?, getting varied opinions from past posts and the titernet.

Was considering GEL until I saw the price!

Hi Trev,

The water level should just cover the plates. If you put too much water in then it will syphon out when it expands during charging up. They shouldn't take any more water than a car battery.

If you are putting that amount in the batteries then I would think that you my have problems with over charging.

That is an excessive amount in so short a time.

Are you leaving them on charge if so you needed a charger that will give only a float charge once they are charged.

Yes that was my thought (overcharging)

We normaly leave the motorhome on EHU all the time when parked up. We also have solar panels. Not sure what is going on but always seem to be charging.

Hi Trev,

What regulator do you have on the solar panels? If you have the Steca regulator and you connected to the panels before connecting to the batteries then the batteries will seriously overcharge.

I had a similar problem and when I read the manual (now there is a novelty :D :D ) it said that if you connect the panel first then the controller doesn't know what voltage your batteries are and continues to pump in full power at 16 volts etc. If this is the case then simply disconnect the solar panels count to 10 and re-connect them.

Being on EHU shouldn't be a problem as they are designed to cut back when the batteries are fully charged.

Guess What!?

I have a steca and I from memory, I connected to the battery last. Thanks for reading the Instructions.
