Re: Is my battery failing and what to replace it with?
Any more I only buy AGMs and the best deal I found last year was a Sears Diehard Gold AGM. Was a bit less a year ago so your price may vary particularly if you have any coupons.
OTOH I have had a failing starter or a resistive starter wire (they get corroded under the insulation - had to replace my ground wire last year) act the same way. One check is if the lights get really dim during cranking it may be the battery, if not then something else.I'd check to see how much the starter is pulling vs the spec and whether any connections get hot when you try to crank before buying a battery.
ps I see white (copper sulphate) around the negative terminal and on the negative wire.
