If a battery is not charged and so runs out halfway through the day is this going to damage it?
Also, if a replacement is needed what criteria do you need to look ofr and what do they mean?
Obviously 12v is the rating of the pump and this has to be a determining factor with the battery, but Ah? What is this all about, is the number of hours a battery will run for depending on the ampage of the pump being used? So a 10 amp pump on a 100 Ah battery would go for 10 hours?
Mine ran out today, at one point the digi screen was saying 12.2 amps and once it started to lose charge it quickly dropped out through 12 and down to 11.
TIA

draining a battery really low is bad for it
as for the size, the bigger the better, i have a massive 110 amp battery from a BMW in the van at the mo, its huge though and it charged by solar panel, so far so good :)
-
So will any battery do, but the more Ah the better?
Well, 12V anyway.
car battery wil die quick if you drain it down, I went through 3 in a year
I had a leisure battery and killed that aswell, I have a marine battery (so I was told) in one van and direct connection in other van

yes, try and get the type you can top up the water inside ;) and keep it topped up
it'll last ages
i used a old car battery from the recycling skips, it was 4 years old when i got it, i still got 18 months out of it, i think it would still be on the go, but i dropped it on the drive and it split open
get a nice solar charger, mine now doesnt get charged, the sun keeps ontop of it

Chewing gum from the recycle centre.

Ideally you need a battery that would last 2 or 4 days, and charge it every night or every other.
A battery needs charging when it's half discharged, or gives a meter reading of 12.05 volts, this is what manufactures recommend for maximum battery life.
I use an 85 amp hour, and charge it every other night

i dont know of the top of my head, i looked at so many, it was either 2 or 3 amp ( which i read as it would put 2 or 3 amps back in per hour ) which when you consider summer daylight hours works about right,

I charge my batteries every night and they have lasted years, like anything else look after it and it will last.
-
i used to use leisure batteries and they kept dying on me, now use a cheap 35ah car battery and charge it every night and 7 months still going strong.
-
Same here, given up on leisure batteries - don't seem worth the extra expense.
-
And me, exactly the same. My battery is over a year old now and still working fine. Just the cheapest car battery from the local tyre garage. Blow those leisure batteries.

i think i got what he was saying so how often do you recommend i charge battery

Too many variables to give a precise answer.
1] what amp hour is the battery?
2]] are you using an electronic flow controller?
3] how many hours a day is the pump runniing?
The only way you will really know is to run a fully charged battery until it goes flat,
record the number of hours it has run, divide the number of hours by 2.
If your battery lasts for 20 hours, it should be recharged when you have done 10.
I have a compact round, so my pump is running most of the day, using a Varistream means that my pump is not continuously running flat out. I recharge my 85 amp hour leisure battery every other night, if it was only a 40 amp battery I would need to charge it nightly.

If you want your battery to last then charge it every night, it may be a pain in the butt to do but you'll be rewarded for it in the future.

I have 2 in my van and connect with a set of jump leads if i get caught out.
I charge the main 1 every couple of days and the other 1 every week.
-
I've always charged my battery every night, but have got through four in 2 years.
Jump leads for me by midday lately.
I'm just going to end up permanantly wiring it to the van.

Leisure batteries are not up to the job. You need to check out the deep cycle gel batteries, they are dearer but they will last longer.
I reckon the battery manufacturers are just about sussing out the kind of battery that we need, because the kind of demand we put on these batteries is quite unusual.
I have thought about the solar panels, as well as the split charge relay, to help keep the battery topped up, but haven't bothered since getting this new battery, it has a 10 year guarantee, so we will see.

Does anyone use mobility scooter batteries?

I would have thought that's a leisure battery isn't it?
Does anybody use a mobility scooter for work...? ;D
