Hello, & good evening
I'm just curious about how a standby battery in a control panel is checked for its charge rate. Do you need a special tester to do this?
How can you tell that a battery is still in good condition, after say 3 years and minimal mains power disruption. The DVM can only give you a voltage reading of 13.8v, that really doesn't tell you about the charge rate or condition of the battery cells.
I only a few days ago replaced a battery in a 9800+panel which was going strong since 1999 ( changed it as a precaution), I measured the voltage, showed 13.8v.
How could I have in this instance checked the battery's charge rate?
Any reply appreciated.
Thank you
