no, he really didn't... your battery won't charge if the charging source is only 10v.... UNLESS your battery is below 10v. when you have a dead battery, it might only rate 6-10volts... a 10v battery has very little juice if any. the charger should be at least 13v otherwise it'll do a poor job.

A 10amp charge is meant for a quick jump start. go for a 1-2amp trickle charge, its meant to give a much fuller charge.

Charging batteries is like pour a glass of guiness. if you do it fast you will fill up the glass, but it won't actually be full, it'll be a wierd frothy mixture of liquid and air bubbles.... You'll get some, but its not really a full glass. You pour it extremely slow and you'll actually get more in your glass.

remember, batteries use chemical reactions to produce electricity, it takes awhile to get all the chemicals set up for those reactions when re-charging.

Yeah, 10 amps or less. 2 amp charge could take as much 24 hrs to fully charge a dead battery, 20 amps will do it in about 4 hours. Quick charge (about 1 hour) needs at least 30 amps. Jump/Engine Start on my charger is 275 amps.

Any time I quick charge I remove the - battery cable...charging volts can go beyond 16v when charging is near complete.
