P500 Lawn mower battery as second battery.

[Red500]

I purchased a battery for my lawn mower this summer and a month later the plastic transmission went out. I'm thinking of using it as a second on my P5. I know it's not the best solution but I've got it so I want to use it. What are your thoughts on this.

I used at lawn tractor battery (U1 340cca/45rc) for 3 years on my P500 and tied it in to my winch contactor and it worked great. If you already have it sitting around, you should use it.

That's kinda what I was thinking.

If running independent should be good. Only thing I’ve read is that 2 batteries on same charging circuit should be same specs.

Use what you have, and when it's time to replace it remember a Rhino battery is the same size, and can be had in AGM with good reserve.

Been running a Die Hard gold in a battery box under the seat for about 4 yrs now, wired in parallel with the stocker.

Will that matter if I use an isolator.

Nope, it'll work fine. Just mount it in an area so if it leaks or vents it wont get on anything critical. A lawn mower battery is going to be of the lead/acid variety (most likely).

This one is a sealed led acid so not really worried about leaking. Plan to make a place under the driver seat for it.
