Title: can a controller drain a new battery?
Post by: dazmond on February 10, 2015, 06:16:22 pm

used my pump for 6 hours solid today.by 4pm the battery was reading 10.5 and flashing BAT on the controller(its a streamline digital).ive had it for a couple of years with no problems.

the battery is a brand new leisure 75ah.

when i bought it last friday i had to charge it up for 6 hours before it was reading a full charge.not good methinks as your not supposed to leave a leisure battery beyond 50% charging capacity.

any ideas lads?could it be that ive bought a duff battery? >:(

Spruce explained to me that the varistream still takes power even when off.

I fitted a separate switch and it stopped the drain.

Sounds like the battery is duff thou or needs a good charge.

While ya there, through that controller in the bin as well  :P

If you're taking it back i'd consider a larger 'ah' as well mate, less chance of it going under half charge if you charge it every night, so in theory it'll last longer

Dazmond you should always check the condition of a new battery by charging it until its full and leaving it
overnight connected to nothing.
Then check it with a multi meter and it should read 12.8 anything below this and its not at a new condition.
The fact that the battery needed charging when you got it home tells me its a dud.

Dazmond you need to let the battery sit for at least 8 hours disconnected to get a true reading.

we had a halfords smart charger, it would show fully charged after half an hour, no matter what state the battery was.

    I thought I would include it as so many wfp window cleaners have battery related issues.

    Here is a conductance tester. They aren't cheap mind you
