heres  the thing.

Went out as usual this morning working happily away when i noticed my flow wasnt quite enough so went back to the van to turn up the varistream

Shock / Horror the dreaded green light was flashing 10 to the dozen meaning the battery needed charging

Shock / Horror 2  id only charged it a couple of days ago and the window on the battery was indicating that all was good....

So can i set my back pack up to feed the 100m mini bore or shall i just take the battery out of the backpack and use that temporarily ......

you only charge your batery every few days? remember that they dont hold there charge as well in colder weather. maybe charge every night.

[MNWC]

yeah i only charge it when it dies ......... prob every weekend........is that wrong then,should i top it up everynight

Its 85 amps leisure battery had it for about a year.....

[Lee Pryor]

we charge ours every night, no problems yet

You should never allow your battery to discharge so far.  Although they're called 'deep cycle', they're no different from an engine starting battery - charge every day

fit a split charge relay. £25 quid from ebay, and never worry about charging again.

I have them on both my vans, best £50 i have spent in years, and the battery's last twice as long so they pay for themselves

There`s split chargers and there`s split chargers from what i`ve heard,the same goes for alternators with most vans if you use hot water especially you should upgrade them.

Deep cycle batteries and car batteries are different. Deep cycle batteries have thicker plates to cope better with a greater discharge and charge cycle. Therefore they are better suited to WFP use. Car batteries have thiner plates as they only need to turn the engine over for a short period, the rest of the time they are on charge. Both batteries should never be discharged past about 75% of their capacity.

If it took a 'couple of days' for it to go flat, why do you need a new one?  I'm using one which is at least 4 years old - when it was new it lasted four days, now it lasts a day, but if I charge it every night ir's still good for a days work (pumps about 350lt before it gives out)

just got the back pack battery out 

Its about the the size of 4 fAg packets piled ontop of one and other 

ian your right ill wait a bit

how long do you charge yours up for ?? is it overnight ??

Is it sealed? If not check your water level is just covering the plates.
Leisure batteries should be charged when they are 50% discharged. If you have a meter the best time for charging the battery is when it gives a reading of 12.05 volts.
Leaving a battery to fully discharge is a sure way of damaging it. I charge my 85 amp hour battery every other night, and they last for ages.
A discharged battery lets sulphide build up on the plates, and this is what knackers them, Halfords do small tablets called Bat aids, these can help break down the sulphide build up, and allow your battery  to charge again, obviously these are useless for sealed batteries.

They seem to work better with newer batteries I've found.  I've started removing mine once or twice a week to top up the charge and hopefully make the battery last longer.  Maybe you do more mileage than me as well.  If it weren't for the relay though, I would probably take it out every night to charge so it's a big help as the battery needs to be carried up steps to my flat.
