bad cell in battery?

[TopCatGr58]

I put it on a tickle charge (2amp) overnight, took it off this morning, went to work in car, came home with a multi meter it read 12.87 I turned the key on and it dropped to 2/89 then slowly started climbing. I put the charger on and could not get enough to turn it over.

Hey Brant,

The voltage he stated it dropped to looks like it was 02.89....think he hit the / instead of the . but definitely a 2(two) volts....not 12! With that level of voltage drop...it looks toasted to me!

But he could charge it fully, and then take it to the autoparts store for a LOAD TEST just to be sure!

Not being present makes for a hard guess with this one as you already know. I,m gonna go with one or more common bsd ground connections putting an excessload on voltage draw before condemming battery.
