Deka 245 AGM 8a8dltp
Pros: This is a very heavy monster duty battery with thick plates and fair Amp hour ratings for a 12 volt unit. No need for acid check. Less corrosion in the battery box. I have 3 strings of 245 AH on a 48 VDC solar system. Most of the information is very clear but I still have questions. Does AGM type of battery need to be equalized? What is the voltage that must be set for the absorption stage? What is the cycle of life on a 20% Depth of Discharge, 30% DOD, and 40% DOD, knowing that 50% an lower DOD's are not recommended. This information for me is very important and I need to know since some information is not clear enough and the retail seller wasn't to helpful neither. I will appreciate your help.
Cons: I cant tell to much about cons except for the size that it's huge and you need a good space to accommodate the batteries. Another thing is that the amp hour rating is not as big as the price. The very last thing I would say is the lack of information related to cycling and depth of discharge and life expectancy in days or years.
Other Thoughts: Other than that is a very good product that should do what is meant to do. I guess the time will the me how good they are and how long they last at a certain depth of discharge. In my case I discharge my bank @ - 25% daily leaving it about 80% charged and the most would be abot 35% discharged some days after a few cloudy days. I would like to know the life cycling @ 35% discharged daily. That will be great telling me how long they will last!
