FAQ:

Q: Should I Disconnect my battery to charge it?

A: It isn’t necessary if you are using a conditioning trickle charger to keep the battery at 13.5 volts when the car is left for extended periods. If you are using a full-power battery charger, then you should disconnect it.

Q: Can I Disconnect my battery while the car is running?

A: In theory, if your alternator is working and providing power to the car while charging your battery, then once the car is started, disconnecting the battery shouldn’t cause the engine to stop running.

Q: How do you disconnect a battery in a car?

A: Disconnect the battery then unscrew the brackets holding it in its tray. Car batteries are heavy so lift the battery up, out of its tray with care. Use diluted baking soda mixture with old toothbrush to brush the tray and connectors. Do not put the new battery before they dry.

Q: What is a Master disconnect switch?

A: Master Disconnect Switches designed for 12 VDC vehicles (Truck, Automotive, Marine, RV) to disconnect all circuitry to reduce possibility of theft and accidental electrical fires. Available in keyed or lever versions, with or without indexing pins, and various sizes of terminal studs.
