How To Revive A Dead Battery?

[NYTSKY]

Hi all,

My car has been sitting for about 3 months and the other night the alarm went off, telling me the battery was dead.

When i hooked my trickle charge to the battery it does not start charging (just stays on standby)

I have been told that the battery needs a very small amount of charge to get the trickle charger going?

If i leave the trickle charger hooked to the battery will it eventually start charging it?

Just to add the battery is less than 6 months old.

CHEERS

Have you tried starting the car with jumper leads and charging the battery with the car on?

Dave jump start the car, let it run for a bit (or take it for a quick drive) then put the trickle charger on it.

I run a trickle charger on mine now aswell (don't drive it often enough and the battery goes flat) and when I first went to run it I had to jump start the car.

Give it a go.

OK ill give it a go.

Just to add - you might want to check that the water levels in the battery are ok as well (if it isn't a sealed battery it might also need a slight top up, before you boost and charge it).

ok, forgive my naiveness here, but aren't skylines susceptible to damage from jump starting?

use the more expensive leads with surge protector

think i paid $60 for mine

no. like any car they are only susceptible to damage when being jump started by idiots who don't take care when doing it and might do something stupid like take the leads off one car (leaving the other car still connected) and then hold the leads in 1 hand and let the clamps touch so they arc out and ingore the zapping noise that is happening as the clamps weld themselves together and start frying the electrics.

i've personally jump started dozens of fuel injected cars from other fuel injected cars and never had an issue. the whole thing about it causing damage is a very rare occurance. i don't persoanlly know of anyone who has ever had an issue with the ecu failing or anything like that because of jump starting.

thanks for that mad082. just confirming procedure, connect negative to negative, and positive to positive correct? and the reverse for lead removal.

I had this problem(stock r33 oem battery) I cleaned it all out nicely by emptying the acid, then hosing the cells thoroughly to get all the gunk/shit out. I just rinsed it with some distilled water, and filled it up again with some more clean distilled water and left it on charge overnight. That battery lasted me over a year after I cleaned it this way.

also give the terminals a clean up

lead acid battery often won't survive being dead flat - its possible it just won't hold a charge again. I've lost a few over the years by leaving them dead for too long.

dry cell batteries handle this sort of thing pretty easy
