Two questions. (1) 2013 Toro Timecutter. 23 hp Kawasaki. I bought a battery Feb 2023 and was told by the sales people 3-6 mo warranty is all they'll offer now. So, I bought one at Lowes with a 6 mo warranty, the best I could find. I went out to crank it today. Dead. I tried 8 amp and 12 amp but charger kicked out when the red check light came on. 2 amp wouldn't work either. I paid about $60 for that little battery and now its worthless. Anybody got any idea where I can get a good one? (2) Can I jump start this mower off my truck battery?
