Any suggestions or recommendations for a replacement battery for L355-SS. Just picked up and battery is 13 years old so I figured I would replace it (had to jump it initially to start).
Seems OEM Kubota Part Number is superceded from 32360-3320 to 70000-90003. Kubota dealer has listed MB Tractor for $321.23
Looks like 30H battery group.
I've seen the Napa commercial brand is about $175 for 760CCA, Oreilly fleet $137.99 760CCA.
I'm in Maine so do want something that will last winters. Any suggestions would be greatly appreciated.

I have a Napa battery in my Kubota and I am very happy with it.

Avoid DieHard from Advance Auto IMHO. I've had bad experiences with them.

Keep in mind I'm from Virginia though, so very different winters.

@Caden Thanks for your opinions and experience. I right now am leaning towards the NAPA battery, they also have a 20% coupon until tomorrow.
I just think the Kubota battery is way overpriced, unless it manages to last twice as long as the others the premium doesn't seem worth it.

@Caden Just went ahead and ordered the Napa battery since it was 20% off and you had good luck! I believe that is what the 13 year old battery in there was. Im picking up the tractor later this week so hopefully I cross-referenced the battery right.
I appreciate the help.

@Caden I had to order to get it shipped to store, my local NAPA did not have in store. Yes the charged me $27 for the core upfront on the online order, I will have to get the credit once I bring back the old battery once I get tractor home. Hope that helps

Just be careful when you are installing it. There have been stories about people hooking them up reversed. Cable color is not always correct on old machines and I think Kubota sometimes used black positive cables and bare ground straps.

If it was me I would look at the existing cables and probably replace them with new ones if they look at all questionable. It just eliminates electrical issues with the old cables and connections.

@Russell King Thanks for the heads up. I am also going to triple check that the battery positive/negative are oriented on the same sides ( I have also seen them reversed on certain batteries). I might get colored Electrical tape if they are not color marked and wrap the positive with red electrical tape. If they are brittle maybe I will just replace them

For anyone looking for same battery, NAPA no longer had the one I ordered. The superceded the one I listed above it to part # 7237. Which works because its a 950CCA battery and they have it in store for me to pick up.
