Only JUNK chargers do not have a timer. Hello Kalifornistan.
The problem with smart chargers isn't only they do not fully charge a battery.
The BIG problem is they have the durability of a soap bubble. Eighty bucks spent eighty bucks wasted. Smart chargers will blow up on a trip. Then other than being short eighty dollars, where does that leave you?
A high amperage Power Max pre-wired as a charger would be the best choice. Stow it as a spare. Or use a Megawatt and that timer.
At one time I had a stack of <3-year-old Die Hard SMART chargers. And another stack of SMART chargers. The SMART part was 100% the failure. Absolute junk circuitry.
