crown wav charging problem

Hi I don't know if some one can help? My problem is that after the truck has been on charge the bdi shows a full battery but after using the truck for 15 mins the bdi drops down to nothing and wont lift.
I have tested the batteries and charger all seem ok I have also swapped the bdi from another wav i have and still have the problem has any one came across this problem before and can advise many thanks.

well the problem with GEL batteries is they can take a surface charge and fool the BDI into thinking they are good voltage wise but when you load test them that will tell the real story. AGM batteries are the same way.

Those type batteries are great because they hold a strong charge for longer than lead acid batteries, but thier falloff point even tho is longer than lead acid batteries are they fall off real quick when they do. The Pro's being longer stronger discharge rate before falloff but the Con's are when they go bad its not gradual, they usually just go suddenly.
At least from my experience anyway...

hi phil,
it does sound as if you have a battery issue
swaping out the bdi proves it is not bad

when you checked the batteries did you test each one individually?
load test them each to see if you have one or two that may be bad dragging down the whole pack?

what kind of battery are these? lead acid? AGM? Gel?

just some thoughts to ponder ;o)
