5 year old batteries while still viable are going to be on the down slope in golf cart battery lifespan; they made take a charge very well as did my 3 year old fleet batteries. But they lose voltage quickly while just sitting and slump badly under use. Take some voltage readings while under load if they are dipping below 42 volts they are going out the door.
Also that new battery soon became no better than the old battery as it gets overcharged due to the older batteries discharging faster and needing more recharge time...

Well I have ran a quick test. 50.4 volts stopped prior to test run. Charge indicator near 100%. Under loading getting up to top speed volts dropped well below 42 volts, 39 and maybe a little less. Once up to top speed levels out around 42 volts. Ran maybe 1-2 miles total.
Returned home and stopped, around 49 volts. Charge indicator showing a little over 75%.
Batteries may be at the end of life........ Thoughts?
