Just as I suspected...there is a dud in the mix. I had a feeling it was this battery because it had gotten a little low on water a couple of months ago - I topped it off and it seemed to be OK for awhile but I reckon the damage was done. Unlike the other 3 batteries it was also bubbling away and warm to the touch - NOT a good sign. The others all checked out at 12.7 volts. Lost this one after only two and a half years of service. This particular battery model (Duralast/Marine 29DP-DL) has gotten some bad reviews but I thought I would try them anyway. Could very well be that I lost this one only due to carelessness. I will buy one more of these (on sale for $120 at AutoZone) but if I get another dud in the next year I will go a different route. Not a great idea to add a new battery to a 2 1/2 year old bank but I will give it a shot. Until the next battery bites the dust, I will check the water levels monthly from now on instead of every 6 months. (FYI - I got almost 6 years out of my first set of golf cart batteries.) 99,106,82,0,B
Part of my morning routine is to check my battery banks. Two days ago I discovered one of the 3 batteries left in my dying bank was really hot. Not good. Removed it from the bank and placed in out away from everything just in case it decided to go up in flames (or explode)...the main reason I check my batteries daily. I think it is time to put the new batteries into service and retire this group for good. Just so happens I shot a video of the switch which will be posted soon. 90,93,54,0,B Note: my battery set ups are not very pretty and are one step above Frankenstein - but they work for me. Don't do as I do.
