Location: Kronenwetter, WI | After having my 3-bank Dual-Pro (15 years old) charging my batteries for 2 days, I noticed bank #2 was red, indicating incomplete charge. I opened the compartment where two of the three batteries are kept and I noticed it was VERY hot inside the compartment. The battery that was reading full charge (bank #1) was warm. The battery kicking the 'not fully charged' indicator was HOT to the touch, not just the terminals, the sides of the battery as well. A smell was evident. I disconnected both batteries and put a voltage meter on each and got the following readings:
Bank #1 battery (charger indicated full charge): 7.8 V
Bank #2 battery (charger indicated NOT fully charged and was HOT): 12.8 V
Bank #3 battery (charger indicated full charge and cool to touch): 12.9 V
Batteries have previously not given me any issues and are EverMaxx 29s purchased in 2013---yes, seven years of service and they get used 3-4 times per week all season long.
My question is why would the HOT battery with the bad indicator be at 12v but the one reading full charge be at 7 V?
I'm thinking I need to replace all three batteries and also get a new charging unit.
Thoughts? |
