I have been using this charger on an off for about three years now to charge car and motorcycle batteries after prolong inactivity as well as charging and "revitalizing" UPS battedries. The charger works realizably whenever I use it, which all together over this time happened around 10-15 times. Thus far, no complaints - works as expected.
