If you are worried about quality buy TROJAN or DEKo(spelling) batteries. Normal life expentancy under normal use is three years. After that you are living on borrowed time. I got this info from a golf cart manufacturers rep. An amp hour meter is absolutely neccessay for a cruising boat, you need to make sure that the batteries never discharge below 50% or their rated capacity.

Based on info. learned to date I''m seriously thinking of going with Trojan. And spelling is Deka.
Prices vary between the two of about $10.00 with Deka being higher. Weight, amp hours per 20 hours usage and warranty are basically the same.
Big issue now is battery compartment size in the salon below the sole.
Thanks

Four batteries are sufficient for normal cruising use. As for location, are you aware that seawater and battery acid produce chlorine gas when combined? That is the only major drawback to wet cell batteries on boats. If you are planning to place batteries below the sole I would seriously consider making the compartment watertight and providing it with a snorkel into a high spot in the engine compartment. By products of charging are hydrogen and other gases that you do not want to breathe. Antoher item you want to invest in is a specific gravity tester, this will allow you to identify weak cells. Not all batteries are good even if new. Once you leave the states warranty replacements will become a headache.
There is a lot of battery information in the Ample Power website, some of it is self serving but most is very informative. Don''t forget about proper size fuses there should be one coming out of the alternator and another between the battery bank and the electrical panel. The only unfused connection allowed is between the batteries and the starter motor.

Best wishes

Sealed battery boxes under the salon sole are above the bottom of the boat by several inches. Have not had any problems over the last two seasons with water coming in in that area.
Have a gravity tester.
Have visited several sites involving battery info. including Ample Power.
When I purchased the boat the prior owner had six 6v batteries hooked up for the house bank. Thus I''ve kept it that way without problems. But he never replaced all at one time. From what I could determine he purchased two new every three years. The marina electrican cited several of the older batteries were low and drawing from the newer ones.
I''m going to replace all six and go from there.
Thanks for the info.
