Some modern cars, like Corvette have some interlocks very sensitive to battery voltage. Others have gone 8+, though they did not have the correct upper Voltage.
#Optima battery hold down manual
Your modern car manual for these AGM batteries tell you to disconnect it if going on vacation.Īlso have had some misses with Optima, battery that die in 3 years. Even a new Optima in my modern car, has to be surface charged every 2 months if sitting. In fact, I never charge it and it is over 5 years old. My 70 RR has acid battery and can sit for 4 months and still be fine.
More so, if a car with active electronic draws. I would be okay keeping this battery if it can be saved but if it is too far gone, I'm looking at a change. There are smaller and lighter batteries that may be a better way to go. These things are expensive and heavy too. I may have to get another battery but I doubt I'd get another Optima. I wonder why the battery charger didn't sense it was discharging and kick into CHARGE mode.
Yesterday I charged it again, it peaked at 11.75 volts so I disconnected the charging unit and tested it today. A few hours later it was down to just over 9 volts. On Wednesday, it charged up to 11.7 volts then the battery charger clicked over to "Maintain" mode. I have a Schumacher battery charger but charging one of these types of batteries isn't as easy as it is with a regular battery. The most recent one was bought in June 2016. I thought that the Optima would be a good choice My thinking was that they were supposed to hold a charge longer than lead-acid batteries. I've had an Optima battery in my '70 Charger since around 2003.
