Does anyone know of a good replacement battery for the 2002 P38? None of the auto parts stores or wal-mart are showing that they have one that fits.

From researching the board, I've found that the DuraLast Heavy Duty part #31-950 will work.

I know that I need 900 Cold Crank Amps.

Any suggestions?


Thanks!

You don't really need 900 CCA, but a big battery is always a plus. I usually just go the shop and ask for the biggest one that fits (not only for the Rangies, but for all cars). I found the 110Ah ones as used in Defenders also fit, and perform excellent. Any battery (preferably from a known brand) over 75Ah will do, but try and find at least 95Ah.

Interstate produces the "correct"'battery for the p38, and very good batteries as well. Independent LR shops that I trust will put in a new interstate battery as the 1st step to any electrical troubleshooting or starting issues.

The largest delco battery is what I finally purchased after the original interstate battery appeared to fail. Without records I think it was original and therefore lasted 7 years plus. The delco was 165 Cdn. $'s and has the 950 CCA recommended. All appears well since the delco went in. I'm sure you would be happy with the Interstate.

I have an Odessey PC1400 that is working well and has done so for about 6 months now.
You can probably get 2 of these in for the size of the normal battery.

I purchased my last one at Batteries Plus. It's a Ray O Vac but according to the clerk there's only a few manufacturers of lead acid batteries in the US and they make all of them. This one looks exactly like an Interstate and was a few bucks less. 1100 cold cranking amps! Really helps when it's at work all day in the winter and temps are well below zero.

Thanks everyone for the advice. I looked into Batteries Plus but they were $30 higher than everyone else. I also looked at the Interstate Battery but I couldn't find a vendor that had it in stock. It would have been a good price had I gotten it. I ended getting the DuraLast 31-950 from AutoZone. Note that I had to purchase the screw-on posts.

Also, mine that died was the Interstate option. I had only been in the Rover since around February of 2008.

I have it in and everything seems just fine. Will post if anything catastrophic occurs.



Thanks!
Jon

I just replaced my dead Interstate 31P-MHD that seems to be the original battery from the date code. Pretty impressive. I wasn't able to get the Interstate today (Sunday), so I got the Sears PM-1 marine battery. It was a perfect fit. I used a battery powered car starter to hold power to the car while replacing the battery. That worked, and I didn't have to redo any codes. I'll see how long this rather expensive and pretty battery lasts.

Regards,

Austin

Jon, it is very common for RRs to keep chewing out expensive batteries. The reason is that you are undercharging it due to a poor ground and or poor positive connection. Save yourself a heap of trouble by running through the electrical sticky and fixing it now. By about the third expensive high quality battery in 3 years most people work out something is wrong with the car and start to check it.
