" ... I used this in hotel rooms across the USA to charge batteries for my boat ... "
" ... Quality roll around charger . ... "
" ... This is our third charger of this brand in 20 years. ... "
" ... I did not expect this charger to be as gentle on the batteries at the lower settings as it is. ... Compared to the (Century brand) compact 2/10/55a charger I had been using, ... this Schumacher charger starts put at a much lower voltage for the various settings, and ramps voltage up much more gratually. ... Connect (small) Century charger set @2a = charges at 14.79v ... Connect Schumacher set @2a = charges at 12.90v ... Immediate voltage after about 2 hours of charging I swapped chargers ... Battery A 13.34v (initial reading after removing small charger) ... Battery B 12.98v (initial reading after removing larger charger) ... the Schumacher charger I'm reviewing is perfect, ... maybe the 2a setting is too gentle (or maybe it recognized that Battery A was already overcharged/surface charged and dialed the voltage back based on that), ... Glad I bought this charger, ... "
" ... I got tired of messing around with the 60 dollar chargers. ... "
" ... Charges batteries, that's what I bought it for. ... "

" ... Battery A = 12.74v ... Battery B 12.52v ... I suspect my "shelf batteries" (batteries for seldom used vehicles) will last longer than they would have with the old charger I had. ... "
" ... Much needed at my property that is a vortex of battery killing wonder. ... "
" ... Charges batteries, that's what I bought it for. ... "
" ... Good battery charger and booster. ... "
" ... We are able to take this with us incase we need to charge a battery for anyone else. ... "
" ... This one has been in use for 6 months and it does a good job with both my 12v and 6v batteries. ... "
" ... You can set a timer and have the charging stop after whatever time interval you want, but how do I know how long my battery needs to be fully charged?? ... "
