I'm an automotive technician and really liked the Energizer charger I bought from Revain. I plugged in my multimeter and monitored the charging process while the charger was connected to my battery, measured the voltage and current and it showed it was exactly to spec. While it is too early to tell how long the charger/maintainer will last, I am very happy with what I have purchased. Out of all the options on Amazon, I think this one is the best, not only for the options and features, but also because it's Energizer branded. The menu is simple and clear. The display shows the battery voltage and the charging time of the battery.
