Yeah ,I guess after 6 years,my 2002 Ranger XLT 3.0L 4X4 offroad ,battery,was dead today.So I'm proceeding to charge it at 2 amps.I have a pretty "new" Exide Megacell battery charger/booster,optional voltage/charge rate:10/2 amp.I have it set on 2 amps now,but had it on 10 and the meter needle was "flickering" and the green LED,that supposedly tells the charge is full?AIN'T SO! I had to add an empty clean Dish detergent 25 fl. ounce bottle of "good" water.I had a New Hydrometer also,AND it showed full chage too!Before I added water too!The water,however,was ,above the plates ,when I started out.Filled cells to "split ring".Is this gonna take ALL day? Now I,like many of us,worked years in a service station,and have some knowledge?Been a LOOOOOOOG time since I charged MY battery(OEM),on this Ranger. I know I should go "down"(80 mile roundtrip) to get a "new" one,but I think I can "bring this back"? I got a black and Decker Booster/portable 12 volt power pack too,and it worked fine.Started her up,drove around the Trailer Park,Parked it,and NO! I didn't expect it to be charged back up.I just want yoose folks to give me that confidence,that I did everything I could,UNTIL,I go to get a NEW one? Like I say,been a loooooong time since I had a battery/replaced/go dead! I cleaned the terminals,etc.,nothing unusual either.Think I'll bring this battery ,"Back To Life"? Thanks Learning ,ALL OVER AGAIN!

12.75 volts doesn't mean much. You still need to have some amps or umph to crank the vehicle. 6 year old battery.... probably time for a new one. Are you sure the alt. is charging?
also dont let a alternator charge a dead battery will hurt the internals of the alternator and cause "alternator death" it is better to charge a dead battery with a charger then a alternator
I AM Charging the battery ,with a Exide Megacell charger.Had it on 10 amps and it said on meter(charger) that it was fully charged! Hydrometer shows dead cells averaging 1200. No variance more than 25 points.I put battery back in last night,started right up.Took it back out to "trickle" charge at 2 amps,meter shows just touching/approaching ,full charge.After the All night 2 amp charge ,I just read the voltage:14.05 Volts! I am gonna get a new battery,Just gotta get to town tomorrow.Thanks for your replies!
