1 amp for those looking. Force mode is interesting though, might bring back a battery from the dead.

FWIW I used this to bring back my depleted battery from a car that sat about 9 months during pandemic ..
It took 7 days at about 20hrs a day to finally fully charge it ( starting voltage was 1.7V)
1 amp might be too slow if you're attempting something similar.. go for the 2amp version

The title says "Battery Maintainer" yet the manual says "Do not leave product unattended while in use." Why would you buy a low power charger, that is mainly only good as a maintainer, if you have to watch it the whole time it is connected and charging.

Quote from sr_deal

have you tested the batter to see what its current CCA is? so car batteries don't need all the capacity they original come with new but its good to have it for the really cold days or if you leave your lights/radio on for an extended period of time. you might be using a battery that is barely adequate and can possibly leave you stranded, so i hope this battery is on your beater or you have AAA.

i would only buy this if you absolutely need a tiny charger. instead i would wait for a deal on a float charger capable of providing more amps for those days you need a slight charge because the car won't start.
