Anyone with hook ups with optima batteries My has been giving me hell the last week or so with electrical issues, found that this morning that my car was having issues starting, come to find out the Red top that I have is leaking/fubared my negitive cable and the negitive hook up. So if anyone can help me out, would be great. It came with the car.

from optima good luck Warranties are handled by the original retail location with original receipt. Most retail locations register your sale with your phone number and can track that purchase.
However, for nearly all people (over 90%) who believe they have a "dead" Optima battery, the battery only needs to be charged. If the battery has less than 10.5v most battery chargers won't do anything to charge the battery using typical procedures, and most test equipment will erroneously indicate the battery has a bad cell.
If an Optima is deeply discharged (below 10.5 volts) most basic chargers will not supply a charge. Also keep in mind an Optima will not recharge properly if treated as a regular flooded or gel battery. To charge the battery, you can wire a 2nd fully charged automotive battery (12V+) to the discharged AGM in parallel (+ to + and – to –). Then hook up the charger to the discharged battery, setting the charger at 10 amps. Leave for 2 hours, monitoring frequently. When the discharged battery reaches 10.5 volts or more, remove the 2nd battery and continue charging the AGM until fully charged.
Typically we recommend charging at a relatively low current, such as 2 amps, but when the battery has been deeply discharged, some sulfation of the battery plates may have occurred. If you charge at 10 amps, the higher current will help to break up this sulfation.
If you have an automatic charger, let it run until the charger indicates charging is complete. If you have a manual charger, estimate charging time by multiplying the capacity (amp hours or Ah) of the battery by 1.2 for a rough estimate of charging time in hours.
In most cases these steps will recover the AGM battery. It’s okay for the AGM battery to get slightly warm during the charging process. Hot to the touch means there’s a short and the process should be discontinued.
Thank you,
