[T3] battery woes... Re: I pulled my Interstate battery july 12th to check the level , found the Interstae MT-42 was leaking.

[J L Stamey]

Once you fix the acid that leaked out and have the floor dried/painted/etc
you could use a battery mat. I've got one and it works well, 10 bucks..
cheap insurance for battery issues...
