Selecting Batteries for Engine Starting
Posted: Wed Dec 14, 2022 11:45 am
In c.2020 I purchased a 1998 OUTRAGE 17 with a Yamaha 130-HP engine. I understand the general principles and functions of an engine cranking battery and a deep-cycle battery and their functions. I don't know much about electrical rigging. I believe that having two batteries equal in power ratings on a boat is recommended.
Q1: will using one cranking battery and one deep-cycle battery cause a problem?
Q2: if the cranking battery cannot start my Yamaha 130-HP engine, will a deep-cycle battery be able to crank-over the engine and start it?
The boat has two c.2017 NAPA-brand flooded-cell deep-cycle recreational vehicle marine batteries rated 500 CCA or 615 MCA connected to a battery selector switch.
Q3: should I replace the port deep-cycle battery with a cranking battery, and replace the starboard deep-cycle battery with a new deep-cycle battery?
