Hi, I have a 2023 Cub Cadet XT1 LT50 The battery that came with the mower is a model number 725-17335 12 volt, AH 11 Cold Cranking AMP 210 battery. It lasted 1 year. I bought an exact replacement, and it is failing as well. I keep it charged. My question is can I buy a regular lawn mover battery at Lowes and use it instead. If so would it damage the engine in any way and how would I install it since the regular lawn mower batteries I see are larger. I am not a mechanic, so I don't know much about the mower or batteries. Also, can you recommend (provide a link) to a good battery and battery charger. I am not sure what to buy. One more question, how do you easily get the screw that hold the battery cables in to line up with the nut below. I struggle with this so much, the nut moves around and I cannot get the screw lined up properly.
