Lamping-battery problem..

[goshawking719 492]

Decided to go for a shine a couple of nights ago, whacked the deben battery pack on charge, its a 12v 18ah battery. i knew it was pretty much fully charged as i charge it after every outing. put it on charge and after about 15 the green light went out indicating the battery was fully charged.

 

Got to the first field took 2 rabbits before i noticed the beam was starting to go rapidly, after about another 5 minutes it had totally gone, had to use the light on my mobile to get back home.

 

once home put it back on charge after about ten minutes it said it was fully charger

 

anyone else have similar problems? did you rectify them or is it a case off getting a new battery.

 

the baterry is only around 6 months old. been used maybe 15-20 times.??

 

thanks

Could it be memory effect ?? try fully discharging and then fully charging 5-6 times. Good luck Rich.

i'd say same as above, or it could be a dud from the factory, seen it happen...

im having the same problem, been told to send the battery back for a replacement,

 

also always use all the power before recharging, that way the cells at the bottom of the battery get used instead of just recharging the top cells and using there lifespan

have you tested the charger,had a similar prob once and the charger was knackered,can you not try it on another battery

i also had that problem and as HBG said it was the charger that was knackered.

its shorting out on the fuse on top of the battery ..i ll bet money on it ..check the wireing out on the fuses .... a mate off mine has just had the exact same prob ..he got my other mate a electrition to look at it ..and thats the prob

had loads of probs with the deben pack so went direct to battery just used the deben connectors an by passed the fuse [i changed batterys to an 18 amp shoulder bat in a decent cartridge bag] lasts longer than the 18amp belt pak i had i use a cheap charger from a car shop one with a fuse in an clip it on the battery might be worth thinking about mate good luck

Get a new charger.

most lamping batterys are sealed lead acid and are not affected by memory,it sounds like your charger or it could be your battery cells shorting inside (called treeing) often caused on lead acid batterys when it has been left without charging/discharging it for a few months. Hope this helps
