Have a 250HPDI, running 2 huminbirds 997 and a 999. Sometimes starting battery dies. Current battery is a Interstate 24M XHD 800 CCA, 1000 MCA. Bought in Nov 2014. Checked battery after fishing yesterday it read 12.56 volts (battery didn't die, it died the day before while fishing) Checked it while motor was running, it read 13.85 volts. Took battery to Autozone and they said it was good. Do need a Bigger battery? Thanks in advance.
