Camano Batteries

[NCheaven]

I've had great success with house and engine batteries on my 2005 Camano, purchased in July of 2017. Looking at the prior owner's maintenance record, the batteries were 8 years old when I had them replaced in 2018. At 6 more years, the "new" batteries are so far faultless. The boat gets electrical power from the dock year round, and has a solar charger that an electrical mechanic said pumps about 200W during good sun for 10AM to 3 or so PM. The volt meter shows 12.5 or so volts when the engine is running. I do not have a diesel generator. Boat is usually in the water all year, except for 2 winters on the hill waiting for bottom paint early warm days in the spring.

So, the question. Camano owners, what is your normal battery replacement cycle in years? Do you change house and start batteries at the same time? Is there a brand/size that you recommend?

Thanks for your responses!

What is the ampere hours of the house batteries? Are you thinking about switching to lithium batteries as you don’t have a generator?

Don't know the Amps on the batteries. They have always been sufficient.
