Title: shagged optima
Post by: Bubba on August 18, 2008, 09:14:17 PM
its shagged i am sure of it  i have tried to charge it using a charger that is suitable for both gel and normal but it just wont take a charge and the faulty warning goes off on the charger sometimes      can the smart members confirm my asumption there is no mad trick to frighten it back to life :rolleyes:

you need a charger with a "deep cycle" (snap on sells them) to have any chance of reviving the tat-tima.......i suspect it's FUBAR

the batteries ive had have been "drop tested" where two metal prongs are placed on the terminals and basically short the battery out. there is a dial that connects the two prongs together which shows the state of charge. note that the battery is shorted out for a couple of seconds or the prongs weld themselves to the terminals.

probably something more high tech out there now

Yep! We have a digital tester at work that tells us what cold cranking amps the battery can supply. It gives state of charge percentage, and state of health (%CCA).

Optimas are way too delicate and I think Peter's description is best - TAT.

You can get a suitable charger from Devon 4x4 for about £70 but it still might not recover the charge. When I spoke to them I ended up buying an Odyssey because of their views on Optimas  :wink:

we have brought them back to life by trickle chargeing them for a week then had them start to take a charge

wahoo, im back after almost 2 months of no computator \:D/

bubba get yourself a charger that has no trip out (or bypass it!!!!) on it an can be switched to a low charge of arround about 2 amps an hour.(or just what ever the low charge is) it took a compleatly nakkered blue top of mine almost 2 weeks to revive but it worked!!!!!

its nakkered again now but its atleast 6 months on an i only use it to start the vehicle once a month an only run it for 5 mins if its lucky. if i was to use it atleast once week as i did when i first revived it im positive it would still be running strong!!!!!!!!!!!!!!!

x2 on the slow charge. I've been given several ex-KJ optima's that i leave on the slow charge for a day or so, they all come back to life.
