the most cranking amps case that will fit the space. There is no "rule" per se.
Quite by accident I was given a Delco Motorhome battery that had the correct terminals and terminal positions and it has been one hell of a battery.
Also I go to the salvage yard and give them my old batteries and pay them $27. per battery for one of those "revived" batteries which outlast new ones costing $200.
I don't know what they do to them but they deliver lots of power and the last one I got has lasted 2 years. For the money I don't complain.
I ave one of those "revived" batteries. Cost me 60 bucks. Fingers crossed Ok foar at least the past three years or so/ I supspect mine is merely dead shelf life surplus from some shop. Markings defaced....
Carl if it has lasted 2 or 3 years you got every penny's worth.
there are videos in you tube of people who know how to revive dead batteries. They change the acid water and shock them with a 120 amp battery charger. Sort of the same thing as a heart defibrilator?
I've also heard it is a good idea once in a while to "drop" the battery onto the floor a couple of times to shake off any sulfite deposits on the plates. I'm talking from 2-3 inches BTW. Anybody know of any truth to that?
My experience is that some makes of battery are way better than others and you tend to get what you pay for. I've used the cheaper ones from tyre chains and they've tended to fail soon after the guarantee expires. I put an AC Delco in my Mk2 in 1981 and it was still going strong in 1994. In recent years, I've bought Yuasa and they seem good so far. I feel that it's worth paying the cost of a good battery as it's a pain to change them.
It's good to keep in mind that a lot of our cars don't go out so much and the batteries may spend weeks or even a couple of months without charge or discharge. I have CTEK chargers attached to the cars that aren't in regular use.
I’d like to chime in here. I don’t think batteries are that much money. I use Maxx Everstart size 24f from Wal-Mart and it costs $130. A while back Consumer Reports rated it as a “best buy” and it is rated 700 CCA and is called their 5 year battery. So that works out to $26 per year. Yes you can spend $200 on a battery but you don’t have to. Modern cars with lots of electronics start doing weird things if the battery isn’t totally up to par. My 2007 Vanden Plas, which has a very good battery starts giving error messages if it sits for 3 or 4 weeks so I use a trickle charger and it is always 100% ready to go. My wife's Lexus just totally shuts down if the battery gets to weak. On the other hand, with the cars we are discussing here there is virtually no electronics and so if the battery gets too old it just cranks slowly so you have lots of warning that it is going out. My overall goal is to not be stranded when I'm out and about so, to me, its worth paying for dependability. Just one man's opinion.
