not wanting to buy a new battery to replace my almost fully discharged (.4 v) one i found this online. take a KNOWN fully charged bat and connect the dead one in parallel with a set of jumper cables, +to+ and -to-. connect the charger to the dead bat and charge for 1 hour. then remove the jumpers and charge the previously dead one as normal. it worked GREAT!! not wanting to overcharge by letting the trickle charger run all night i stopped last evening and i checked the v this am. lost .1 volts. on a recharge mode this am for a full charge. if successful its money in the bank.

bought it years ago at costco and it has been sitting disconnected for a for a long time. the one that came with the green car has been sitting for months and still had 12+v. i used that one for the parallel to 'fool' the charger.

Isn't that the Optima suggested charging recovery mode? I have a 3-year old red top that is sort of funky about charging but won't die. But the battery in the 911 is a 10-year old die hard, so maybe the money isn't the thing. |

Awesome, I was gonna say the yellow ones are supposed to be able to go dead, the deep cycle. Some people do use them for starter batteries. Good tip, I have a red and a yellow at the shop running a sink. (IMG:style_emoticons/default/smile.gif) |

I tried this on a red top with no success. I took the red top to have it charged, but it couldn't hold a charge.
I picked up another red top (34R) on line for 160 bucks, now have it in the car and have the one I couldn't charge on the stand. Any suggestions? Would love to have two good red tops available. Fern |

A dry cell But supposed smart chargers work so I'm trying it The red top is pretty much a write off for me at this point I'm sick of it Shame really , but this will be a last ditch effort and if it deforms or b Then screw it!!!___ ;;;;;;;;;;;;;;;;;;;;;;;;;;+;+;;;;;;;;;;;;;;;;;;;;;;;;;; A prince and a great man has fallen ....

Is that a Lola? Group: Members Posts: 1,523 Joined: 2-June 05 From: Little Rock, AR Member No.: 4,188 Region Association: None |
Optima is an Absorbed Glass Mat (AGM) battery and is a sealed. wet cell type.
A dry-cell battery has far too much internal resistance to give out the cranking amps needed for starting our engines. That's the advantage wet cells have... almost no internal resistance, and it's why we can hurt ourselves if the electrodes are shorted. Massive and instantaneous current flow. You should only use chargers that are certified for AGM batteries to get the most out of them. Generally that means no higher than 1 amp, at least from Optima docs. |

usually if my charger doesnt work I put jumpers on a running car and charge it up that way. an alternater puts out alot more amps than my 6 amp charger so it kinda shocks it. then put it ack on the charger till its topped up. If that doesnt work I usually give up on it. I do have a bunch of old batterys iv been thinking about buying a desulfator or building one. Not sure if it would work on an optima but worth a try i guess

I started doing a bit of expearimenting. With the help of U-tube (IMG:style_emoticons/default/smile.gif) I discovered a good trick of using ebsom salt to desulfate batteries. That paired with a capactive battery charger should repair most batteries. I didnt have any ebsom salt around but I thew together a capaitive charger with spare parts its super simple. and it seems to work great. I got a stone dead battey to full charge. I have yet to see if it will hold the charge but usually they take a few cycles to get them going again. Anyhow I thought id share my findings and I encourage you guys to look into it if you are intrested in fixing your batterys
