Lately my Ship System battery has been showing low voltage (down to 10 and below) after about an hour of anchoring. Fridge, stereo, and C80 are running. I end up running the generator for a good 30 mins to recharge.
The dual gauges at the helm show 12 volts. Engines always start with no issue.
What would you recommend: a) Only change the Ship's Systems battery b) Change the three batteries.
which battery is best suited for the 348 systems.
I read a dual 6 volt golf cart batteries can do a better job for the Ship's system.
Realizing, of course, there are 39 pages to this thread, I encourage you to scan through as this subject has been covered in great detail with a number of options. I replaced my ship's systems battery with an AGM type, added a second and have had great success. It is also a relatively easy install. Bill K. did the golf battery setup, also with great success, but a more challenging installation. Again, each of these setups is detailed in these pages.
If your engines are cranking fine, you need not change your engine batteries. But if you change the
type of house battery you use, it is best not to mix and match (I now have all AGMs - which apparently can be mixed with Lead Acid but it's better not to as the charger has different settings for each. Gels cannot mix with other types).
