If battery light shows red and continuing charge, then return the

do it anyway.

If battery light shows green then all should be good to go.


You need something more precise than red and green lights. The best
way is with a load tester which you can buy at a reasonable price from
Harbor Freight or Northern Tool. Also, as Larry mentioned, a specific
gravity test using a hygrometer is very useful. Last but not least,
test the battery with a DVM after it has been off the charger for at
least 24 hours. A fully charged battery should read about 12.6 volts
with no load or lightly loaded.


Harbor Freight has a new load tester, now. 0-500 amps! I gave my 50A
fixed load tester to a boater who is nice to me and got the new one. It's
a beautiful unit for so little money.

If a man goes way out into the woods all alone and says something,
is it still wrong, even though no woman hears him?
