All orange jacket indicates a metal jacket battery.
Voltmeter Reading State of Charge
12.84 Volts or higher 100%
12.50 Volts 75%
12.18 Volts 50%
11.88 Volts 25%
Fully discharged is 11.6 Volts
(during strobe testing our battery got to 10.5 Volts at which point instead of a dual flash, only would single flash)
(1) German DIN standard test for overdischarge recovery
In this test, a PC925 was discharged over 20 hours (0.05C10 rate) to 10.20V. After the discharge a 5 ohm resistor
was placed across the battery terminals and the battery kept in storage for 28 days. At the end of the storage period, the battery was charged at 13.5V for only 48 hours. A second 0.05C discharge
yielded 97% of rated capacity, indicating that a low rate 48-hour charge after such a deep discharge was
insufficient; however, the intent of the test is to determine if the battery is recoverable from extremely deep discharges using only a standby float charger. A standard automotive charger at 14.4V would have allowed the battery to recover greater than 97% of its
capacity.
