My starting battery for my motor is dying, but the battery seems to be fine since it holds a full charge. Anyone ever run into this problem? Thanks
Starting battery DYING
The battery needs a load test. 12.8 v is a full charge. Doesn’t mean your CCA ( cold cranking amps) are up to par. Once they drop, the battery is useless unless you’re going to use it for LED lights or something similar. Take it to most Auto Parts stores and they will perform load test for free.
You still haven’t said what you’re running on your starter battery?
Pull the caps and check fluid levels. Add if needed and recharge. Maintenance free is not true. May not be the case but I have 4 31's on my boat and 2 times a season check them. Every time I have checked, fluid was needed as much as 1/2gal per battery at times.
What do you mean by dying? Do you run many accessories off the starting battery? If you do some anchor up fishing and run a locator and or live well pump off the starting battery it can draw it down to a point where it acts weak when cranking the outboard, size of outboard matters also.
