Re: Battery maintainer problems
I would not want to run the block heater all the time I was running the battery maintainer. A battery maintainer is intended to keep a battery charge up during extended periods of non-use, while a block heater is intended to reduce the drag of very cold oil on the rotating parts of the engine, allowing the engine to start easier in frigid temperatures. Even at -40C (F) I only run the block heater for a few hours before starting, while a battery maintainer would run 24/7. There is no need to waste electricity running a block heater more than necessary.
