Which CAT battery to choose?

**8r0wndo9** · 15th July 2013, 08:40 AM

After reading the past battery threads I've decided to go with a Caterpillar start battery for my TD5 D2a. Allegiances seem divided between:
p/n175-4370 825CCA start/deep cycle and
p/n 115-2422 1000CCA start only.
There's only ~$30 in it, so has anyone a definitive reason / experiences to select one over the other?
My thoughts were that for slightly fewer CCA (still plenty for a starter), the deep cycle characteristics would be a nice bonus to a single battery setup?
Any comments appreciated...thanks!

I went for the 1000CCA 115-2422 as I knew I was installing a second dedicated deep cycle. Fits the battery compartment perfectly, and starts the TD5 like a cattle prod to a grasshopper

. I personally prefer to have items that fulfill a designed purpose rather than hybrids, if possible.

115 here... Massive thumbs up.

Bear in mind the 175-4370 has stud terminals not SAE. If you want that battery and SAE posts you'll need to buy these: Group 31—Charging Posts for Stud Terminals—Part # 4C-5637, from caterpillar. Cost about $7 or so.

thanks for the comments guys! I agree, 'hybrids' are typically a compromise at both ends and not particularly good at either. I was curious if anyone has had a really good run with them?
Thanks for the tip re terminals Mundy.

I went the 115, can't see the point in a deep cycle for your main starting battery.

X2. It seems to me the degree of discharge that makes using a deep cycle worthwhile would kill the ability of the battery to start the engine. It might be worthwhile if it is your second battery and you want to use it as backup for your main cranking battery.

I bought the 175-4390 (should have bought the 115-2422 with SAE posts) a month ago for $149 plus GST. Great value for money IMHO.

I bought the stud terminals and have not been able to close the battery cover on my D2a since. The post makes the battery just too tall for the cover to lock down. It's still on, just not locked down.

For what it's worth, this does not happen with the 115-2422 battery. So something else for the OP to consider.
