June 4, 2024Inverter battery 150 Ah low back up.
The symptoms point to the battery getting old and tired. The easiest way to test the battery (without the proper test tool) is to find a known load (12v car headlight bulb would be a good example). Measure the current drawn by the bulb from the battery. Time how long it takes for the battery voltage to drop from 12.6 to 10.5v Current drawn multiplied by time in hours is the measured capacity of the battery (approximately, because the current drawn by the bulb will drop as the battery volts drop, but it's good enough for our purposes). If the measured capacity of the battery is significantly lower than the sticker says, the battery has reached the end of its working life and needs replacing. More on reddit.com
