Time for a new battery - recommendations?

I’ve had good luck with interstate from Costco and ever start max from Walmart.

I’ve run a few Optima batteries. They did no better than standard batteries other than use in high vibration applications like boats. Even then they don’t impress.
2x the cost, but certainly not 2x the battery. Maybe a 15-20% improvement at best.
 
I have the Northstar 27F and it's treated me very good for the past 2 yrs I think

There's actually a group buy again for it

**Northstar Battery - Group Buy 10.0**


That battery has some serious ass.

I almost bought two of those for my Cummins.

They are

930cca
195rc
92ah

But it’s 360-400 dollars. Compared to 120 for a MTP-27f which is

710cca
165rc

If I had the money to spend id buy that battery. I forgot I seen those at Cabela’s when they first opened in Hamburg, Pa.

Battery

I used to only get my Diehard batteries from sears, now I get my batteries from Sam's club Duracell because of the great warranty. Last month I was 3 days away from the 36 months and got a brand new battery for free.

Yea dude I compared the stats vs the other ones and this one has the highest ratings:

Pulse cranking amps: 1750 A
CCA rating at -18°C (0°F): 930 A
CA/MCA rating at 0°C (32°F):1080 A
Reserve capacity: 195 min
Capacity - 20 hour rate (1.75 vpc): 92 Ah
Short circuit current 5000 A
Warranty 4 years full

I just pulled up my invoice and I only paid $263.99 for the Northstar AGM 24F battery for my 4Runner. I do remember with the group buy it was a really good deal and I bet I don't have to buy another battery lol.

I also bought the CTEK (56-353) Multi US 7002 12v battery charger from Amazon since I heard AGM batteries should be charged every now and then. Also cuz I'm only on Stock Alternator.

I think the OP should have posted a budget lol. Obviously the sky's the limit for CCA's and amp hours but how much does he have to spend? I'm under the assumption he doesn't want to drop $400 on a battery.

Yea when I seen those north star 27s at cabela’s I blew a nut until I seen the price. I tried justifying it and couldn’t. So I bought megatron plus 27 interstates. They lasted 8 years. I replaced them this past winter. I kept 1 as a spare jump battery. It tests a 650cca yet.

im on my 2nd Interstate in 10 years of owning my Runner. Ive had Interstates in many other cars prior with similar results.
 
Here is my spare starter battery I kept from my 94 ram with the diesel. It’s marked that I bought it January of 2010. It still tests at 88% of its rated 750cca. My MidTronics tester tests it at 660cca. I used it last week to jump start my neighbors truck when his battery smoked to test his Alt output. Yea, a dead battery running at 14.5v and only pushing 1a into the battery. “It’s dead Jim.”

No barnacles on the posts and you can still see the remnants of the terminal grease.

You're right! I'd say my budget is around $200 or so but less is better. I think I'm just going to go with a flooded battery like I currently have in it.

I like the 31 adapter from CBI... any issues with a 31 series battery on an OEM alternator???
 
Correct, 24Fs are *usually 10" while the 27Fs are 12". Width and height are pretty close, 4th-gens use either depending on the engine.

Interstate Batteries | M-27F

*Here's what I mean by "usually", depending on what line there's a 3/4" difference in length, same group size.
Interstate Batteries | MT-24F
Interstate Batteries | MTP-24F


The MTP is the Plus battery. Higher ratings. I can see it being slightly bigger.

If the group 65 had an F reverse post option I’d buy that. It beats the 27 hands down and what Dodge went to for their group 65 batteries in their diesels because they had higher AH/RC rating.

I do not like buying a battery with less than 150rc.

The MTP-24F looks like a great option. Is anyone using this? Are the terminals reversed?

Thanks!
