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?
