Spring 2013 installed four new lead/acid Interstates on my 410DA to replace the four 'BrandX' lead/acid that were nearly four years old and showing signs of their age. This time I used cranking batteries for the port side pair, and deep cycles for the starboard side (house), retaining the factory charger and cleaning up cables, tie downs, etc.
I was never impressed with the deep cycle longevity when it came to keeping the 'Nevercold' and a few lights (incandescent) on overnight on the hook. However, I was surprised after only 8-10 months to find the starboard deep cycle bank incapable of starting the starboard engine (yes, I tried to always remember to bridge the port/starboard banks as to not tax the deep cycles) and barely getting through nights without dead house batteries.
Last night the batteries were shot, after days on the charger. I assume a bad cell in one or both...
Q: With the current setup, should I use cranking batteries for both port and starboard, or is this a fluke and replace the two deep cycles with deep cycles.
Note: No signs of charger 'cooking' either pair, no acid venting, tops are dry and clean and levels good.
