I bought a new 110ah leisure battery in August. I've never run it down to nothing and I've never overcharged it.

Today, after about 4 hours I had to drop the flow rate down as the battery wouldn't supply enough power to keep going. The pump was cycling every now and then.

The thing is, the battery was 13v this morning going on the van and when I connected up to recharge this evening it was 12.5v. According to the volts I should still have had plenty to keep going. The flow controller reads the volts as about 12.5v when the pump is dead ended but once the pump is running the volts are in the range of 11.5v to 11.1v.

I've checked all the cells, none are dry and none are furring. The electrolyte seems clear (from what I could see in the semi dark).

What's going on?

Check your wiring and any connections, there may be corrosion limmiting current flow.

I had though that but wasn't sure. I'll replace the wiring and see if any different. Cheers.

check your wiring and connections, fit a split charging relay in your van and you wont have to take it out or re charge it again

You may be seeing volt drop along the cables. Ensure all the connections are good replace worn or corroded connectors and any damaged wiring. Also ensure the wiring is a short as possible.
I suspect the issue is volt drop along the cable

Have a look at this link as it has more info.

You are overdoing things. It's nature's way of telling you that four hours is more than enough. Go home, put the kettle on and have a few biccies.

I know, I know. I'm working to hard again. Biccies - MmmmmmYUmmmm

Could be the wires are too long. I left them long to give myself options of moving stuff around the van but I will chop them tomorrow and see how we go. They must be about 12 foot long, if not more.

Could also be the type of wire you are using too,

What wire are you using? What amp is it?

[lozsing]

which flow controller are you using , i am using a varistream which has no low batt warning on it and i know that once my battery drops below 12.8v the  varistream does just the same as yours.

I'm not sure the spec, it's the wire that came with the flow controller. It should hopefully be in the right size.

It's a basic digital spring controller, the one that's rebadged all over the place.

How about from the battery to it?  And from it to the pump.

All the same wire apart from pump to controller. That came with the pump.

I bet its the length of wires. i'll know tomorrow and report back.

this is the kinda stuff that was happening to me but i think my problem is the battery , went for the 85ah £55 inc delivery from ebay
your batt seems way to young to go wrong i got 3 years out of mine and i was treating it quite badly letting it run down often

[davids3511]

Choped 10ft off the wire today and everything improved. The flow rate was better, where I used to have it on 50 now 42 gives the same flow. The battery was still showing 12v tonight when under a load or 12.6v with pump off.

That sounds good then!
