The man has got it straight! This is my first post and have a battery question. I continue to have a battery problem with my 2005 C6. I don't have the ability to plug a battery tender but since I don't drive the car in bad weather. i make it a point of starting it at least once a week. My problem is last friday I had to get a jump start(vehicle wouldn't start) and drove the vehicle to the dealership for them to check out the battery. I was told the battery was "re-charged" and just make sure I start it at least once every two weeks. However, yesterday(Saturday) I went to start the vehicle and nothing happened!. The car has an Ac delco battery which was replaced about a year ago. Any recommendations on a replacement battery? I've seen some members recommend Optima batteries. If I go with an optima battery, what model? Any other suggestions on how often to start the vehicle? I parked it in the parking lot underneath my building with a car cover on. Thank you in advance for any responses/suggestions.
If you do not have electrical access where you store your vehicle, a quick disconnect on a fully-charged battery is also a viable option. “Fully-charged” is important, because many batteries are not fully-charged when put into storage (approximately 12.6-12.8 volts for RedTops & about 13.0-13.2 volts for YellowTops). When batteries are discharged below 12.4 volts and allowed to sit in that state for extended periods of time, sulfation will begin to diminish both capacity and lifespan. Be careful of devices that claim to prevent battery discharge while in storage, but still maintain vehicle presets. Those devices still allow your vehicle to draw current to maintain those presets and will allow your battery to be discharged, although the rate of discharge may be slower.
If you do end up purchasing a maintenance device, the best maintainers are microprocessor-controlled and there are two basic types of maintenance chargers. Fully-automatic, “multi-stage or multi-step” chargers will monitor the battery and charge it as necessary. Multi-stage maintainers will charge at varying voltages and varying amperage (rarely exceeding 2 amps). Some of these multi-step chargers are also capable of being regular battery chargers (7 amps or more). These types of chargers are preferred.
Traditional “float” chargers provide constant voltage with tapering amperage to the battery, even when it is fully-charged. For float-charging, we recommend 1 amp max, 13.2-13.8 volts. These are OK too, but the multi-stage chargers are a better option. Quality units will also have regulators that prevent overcharging.
Since gunterwalker mentioned the "g" word, I should clarify that our batteries are lead-acid, AGM batteries in a SpiralCell design. They can be treated and charged just like regular lead-acid batteries in most situations, but they are not "gel" batteries and "gel" or "gel/AGM" charger settings should be avoided, as they will not fully-charge our batteries and could damage them over time. If you have any questions about our batteries, I'll do my best to answer them.
