I need to replace my cranking battery and i was thinking of using a deep cycle for the job. Ive done this in my truck and SUV for years because of all of the acc plugs the family uses when the truck not running. With all the stuff the cranking battery runs (lights,electronics,pumps, stereo,ect.) it seems like it would be a good idea. My p2 has the original cranking battery which is rated at 750 CCA. My deepcylces have 800 CCA, could i us a similar battery for a cranking battery?basscat24

We have for several years suggested a very large AGM cranking battery. Trojan, Sears and more will do the job. There was a list in the FAQ section from a couple years ago.

1000 cca though a big 31 or 27 series AGM battery will do a great job if it runs 900 cca or so. It is about durable amperage as much as cranking amps. If they spec cca higher odds are they get enough reserve to twist the starter on a long day so they suggest 1000 cca.

do yourself a favor and get the sears. You will not regret it. It is plenty of power to run everything and start the motor at the end of the day. Mercs take a lot of juice to start

x2 on the sears, mine started much better since I made the switch. Just sit down when you price them!

I have been running a sealed lead acid dump truck starting battery made by interstate that was $120. Group 31. 1000 cca. Been good thus far. Power Volt. Reserve capacity same as AGM as well. Spoke with engineers at Interstate in Dallas regarding use and need to recharge. 1 year in and no problems..I get to 2 years and the cost benefit ratio works out. We will see…C.O.D. Jr. III
