That makes answers to this question somewhat moot. Recharging, checking water levels, etc. is very important to battery life. Some skippers have solar, some generators, some only engines. It's really a hard question to answer the way you put it. With good maintenance, well over 3 years should be the norm, easily. __________________ Stu Jackson Catalina 34 #224 (1986) San Francisco Bay, SR/FK, M25, Rocna 10 (22#) (NZ model)

Solar and windgen, never run the diesel for charging, well maybe 10 times in the last 3 1/2 years. I wasnt sure what to expect from them but they've been great. I checked the fluid in them for the first time a couple months ago and added a pint total. When they do die I wanna add more ah's, so I'll look to see what better value is available. I have reefer, auto pilot, LCD/DVD tv, stero, LED nav lights. __________________

I have seen some last 7 or 8 and some only 2 but 5 is the rule of thumb. Where I work we have started using SAFT batteries instead of lead acid an they are projected to last over 10. One issue is the newer batteries pull a crap ton of amps when recharging compared to lead acid. If your charge rsystem is not up to the extra load many headache may result. __________________ Gary S/V Knot a Clew

After that they still had enough life for liveaboard and weekend cruising for another 3 years. They never died catastrophically, but the capacity was very low at the end. __________________

Hella deep cycle 3+ years, Tudor Leisure 3+ years. I bet the Hellas had some potential but I killed them with solar charging. b. __________________
