I opted to replace the current Interstate MB 88 battery with 740/900 amp specs with the same (big freakin' battery). Cost was $104.00 out the door. From now on I'll be checking the water on a regular schedule. Seems to be just fine but I just installed it last night in the parking lot of my wifes workplace. It was recharged Sat night at Napa, I put in back in on Sunday, started fine Monday 8:30am but was dead by Monday 3pm.

I guess it just never recovered from the low water
