Not fun getting my old battery out - darn near herniated a fifth disc - had to tilt it on it's side to get out of engine compartment, and even then only had 1/16" clearance to do so - SO, now what do I replace it with? This was the factory installed Interstate 24M-XHD, 1000 cranking amps, which lasted me 64 months. Want something I can get local and fast. Thanks!
