>> Paul,

>>
>> Bert was right on with his recommendation for a 40 amp charger... you

>>
>> Here is something else to think about...Before you replace your marine,
>> lead/acid 4Ds (which a really a hybrid starting/deep cycle battery, at
>> approx 205 AH), consider switching to golf car batteries (220 AH). Others
>> have suggested going to AGM's but I found that a tad pricy.

>> Here is a link to some reference material...

>> http://www.yachtsurvey.com/boat_battery_basics.htm
>>
>> A true (lead/acid) deep cycle battery can tolerate being discharged 80%
>> whereas the hybrid (lead/acid) batteries should only be discharged 50%.
>> You
>> must be doing something right, however, having gotten 6 years of life on
>> your last pair!!
>>
>> Also, four golf car batteries are also easier to handle than the 2 4D's.
>> Of
>> course, you may want to add a starting battery. This will give you the
>> added
>> confidence to run the house bank way down and still be able to start the
>> engine.
>>
>> There are several of these conversions photographed on the C320IA
