meathead battery question

Post by **Alex** » Mon Feb 22, 2010 6:24 pm

hey guys,

so i bought a deka intimidator AGM battery about 18months ago.

it was in the car and fine for a year or so, i then removed it(cant remember if it was flat or charged) and let it sit at a mates house for about 6 months.

now i wanna go pick it up this arvo, IF it was flat when i took it out, is it likely to be cactus? Im not sure how these gel cell batterys work, with running them flat and killing them etc. Im just slightly worried cos it did set me back a fair few $$.

thanks heaps

alex

if you stored it flat that a big no no. always charge a battery before storage.

what voltage ios it reading now?

it has 7.8v in it at the moment.

ive got it on trickle charge as we speak. See if it charges and holds it, but im not getting my hope up

good way to throw away $500

if it was a flat battery you have a very small chance to get it charged up again, also how did you store it? if you stored it on cement, it drains battery quicker, if you store the battery off cement on block of wood its okay.. normally they can be stored upto 6 mths without charging otherwise it will go flat.

its not acually the cement that kills the battery its the ambent temp around it
cement is used as an example because it holds temperature and takes a long time to warm up over night

if it was stored on a driveway in a hot climate the effects would be far less than if i left a battery on my driveway for the winter down here in tassie

Originally this was due to the outter casing being made of some composite that allowed the battery's charge to escape through the cement. I can't remember what it was made off but it was an old family friend that told me this is how it came about that you don't store batteries on cement directly.

The temp change thing makes sense though. On bush mechanics the aborigines "charged" a battery by the fire before they were able to start their car...
