Hi, my leisure battery takes about five mins to charge and the charge doesn't last ages- one night ish, although I only use a couple of lights and the water pump very occasionally, I don't leave the lights on and just pop them on and off when looking for stuff really. I am told this means it needs replacing. How do I know if it does? What should I expect from one? If buying a new one, what brand and shop would you recommend, bearing in mind I would like it this weekend so internet shopping not an option unless price difference is huge. What price should I expect to pay? Thanks.
 
lot of people will have different opions on what you should get and it depends on budget as well if you need a specific size to fit in a cupboard whatt size is your current battery amperage
 
....

I bought a charger from Halfords as I had been borrowing one that took ages. It shows the charging light for about five mins, then the fully charged light.

I don't know the amperage. It is about the length of my forearm, yellow and very heavy....
 
I have been doing some research and banner batteries are considered to be the best. And they sell them based on the 20hour rating rather than the 100hour rating.
 
Hi Arnold, I had problems with my batteries on a new Dethleffs M/home. They ran low after seven minuets with only two small lights on. I rang the dealer at Painton, and the lady there said they do not cover batteries under their guarantee? So I contacted Banner batteries at Rudgeley, who couldn't have been more helpfull. They spent over an hour testing them with their best equipment, after which the couldn't find a fault. they told me to give it another try, as I was off to Newark show and they would see me there tomorrow. Still no difference and they told me that Dethfeffs, the dealer, and themselves were all responsible. They then replaced both Gell batteries free of charge, after which I had no more prob's, and sent mine off to their lab in Sweden for testing. Two points here are, If you go to a good manufacturer with a back up service where nothing is to much trouble. It could pay dividends down the road. As for the Dealer in Painton, well I have bought another M/home, but not alas from them, despite several phone call from their reps saying I could do with a change, and they will do me a deal. To be fair I dealt with a firm in Bury who couldn't be more helpfull with the few problems i've had. So to conclude. Phil's advise seem very sound.

Sorry for my ignorance but what does the 20hour rating or 100hour rating mean?

You measure a battery's capacity based on how much current you can draw to run it flat over a period of time.

For example:

Battery 1: A 100 amp hour capacity battery, measured at 20 hour rate, would provide 5 amps current draw over 20 hours. Multiply 5 by 20 - result 100 amp hours.

Battery 2: A 100 amp hour capacity battery, measured at 100 hour rate, would provide 1 amp current draw over 100 hours. Multiply 1 by 100 - result 100 amp hours.

Apparently both batteries have equivalent capacity.

But actually they don't. If you draw a larger current, the effective capacity of the battery drops. So if you remeasured battery 2 at the 20 hour rate, meaning a higher current, it might only provide 4 amps over 20 hours. So its capacity at the 20 hour rate would be 80 amp hours, not 100.

The 20 hour rate gives a much better indication in a motorhome of how long the battery might last.

So when comparing batteries, make sure you're comparing apples with apples :)
 
We have Banner batteries which are 4 years old and lasting very well. I emailed the UK importer a few weeks back about a vent tube for one which was missing, next day one arrived free of charge.
 
It's difficult to know what to recommend not knowing what you'll be running off it, how you'll be using it 12v direct or using an inverter of some kind, and last of all how you'll be charging it.

I have a sonnenschein DF180 85A gel battery that suits my needs just fine, but it might not suit your needs
