Recently purchased a farm in Puerto Rico. We plan to install solar next year, but for the time being we inherited a standby battery bank which consists of 8 6V 230AH Duracell (SLIGC115) lead acid batteries wired in series-parallel. I've attached an image of the battery bank and the charger. The charger that came with the bank is a Duralast DL-15D model with the following specs
Input Voltage: 120V AC @ 60Hz, 3.6A, Output Voltage: 6V or 12V, with Auto Voltage Detection, Output Current Rating: 2A @ 6V DC; 15A @ 12V DC
My guess is that this charger is under powered for this battery configuration and even though the batteries appear to be in decent condition (tested with a SG meter and water is at correct levels) I can't get them to charge to more than about 12.4V. Any recommendation on the type of charger I should be using. If you could include a link that would be great.
Also, the previous owner would just connect the charger to the main positive and negative terminals/posts that connect to the inverter. Will that work or do I need to be charging each battery individually. That sounds tedious, but I could do it knowing this is just for standby/emergency power. Thanks!
