Verado Engine Battery Specifications
IMPORTANT: Verado engines require a 12 volt AGM (absorbed
glass mat) marine starting battery that meets the minimum
ratings.
For best performance, Mercury Marine does not recommend
using the more common flooded (wet cell) or gel cell type lead
acid batteries for starting Verado engines.
Each Verado engine must be equipped with its own starting
battery.
If the boat application requires additional battery loads for boat
accessories or marine electronics, it is recommended that an
auxiliary battery, or batteries, be installed.
Choose a 12 volt AGM (absorbed glass mat) battery which
meets the following ratings.
USA (SAE) Verado Starting Battery Rating

NOTE: Do not use an engine starting battery that does not meet
the specified ratings. If a battery that does not meet the ratings is
used, the electrical system may perform poorly.
IMPORTANT: Boating industry standards (BIA, ABYC, etc.),
federal standards, and Coast Guard regulations must be
adhered to when installing the battery. Ensure that battery cable
installation meets the pull test requirements and that the positive
battery terminal is properly insulated in accordance with
regulations.
It is recommended (required in some states) that the battery be
installed in an enclosed case. Refer to regulations for your area.
