We have more or less been asked to document/determine for ourselves what is causing our carts to die on the course and to have charger faults. So, today I went in early, disconnected the charger, and took voltage readings on all the batteries.
Using the axiom that a fresh 12 volt battery will read 12.8-12.9, and that the closer it gets to 12.0, the closer it is to the end of its useful life, most of the batteries were in the 12.6-12.8 range.
There were 20, out of 60, that had readings of 12.4 or lower. Some had 11s and 10s, meaning shorted cells.
Every cart that has been a problem had at least one low battery.
These are 2012s, and have been in service around 15 months.
