There are special battery measuring instruments for the quality of the battery, but there are few such instruments in general users. There is only one multimeter. The following points are summarized in the maintenance to judge the quality of the battery for reference.
1. Judging from the appearance: Observing whether the appearance is deformed, protruding, leaking, cracked, burnt, and there is no oxide exudation at the Screw joint.
2, load measurement: If the appearance is not abnormal, UPS works in battery mode, with a certain amount of load, if the discharge time is significantly shorter than the normal discharge time, after 8 hours of charging, it can not restore the normal standby time, determine the battery aging .
3. Measure with a multimeter:
A. Measurement in battery discharge mode: Measure the voltage of each battery terminal in the battery pack. If one or more of the battery terminals voltage is higher or lower than the nominal voltage (nominal voltage 12V/section), judge the battery aging.
B. Measurement in the mains mode: The charging voltage of each battery terminal in the battery pack, if the charging voltage of one or more of the batteries is significantly higher or lower than Other voltages, it is determined that the battery is aging.
C. Measure the total voltage of the battery pack: the total voltage of the battery pack is significantly lower than the nominal value (for example, the nominal value of the C1K battery pack is 36V). After charging for 8 hours, it cannot be restored to the normal value, even if it returns to the normal value. The discharge time does not reach the normal discharge time, and the battery is judged to be aged.
D, battery start-up measurement: UPS does not start, do not connect to the mains, first use a multimeter to measure the total voltage of the battery, taking C1K as an example, the voltage may be between 36V-40V, is a normal value, the pen does not leave, has been Penetrate the multimeter's instructions, and then connect the power button. If the total battery voltage drops to below 30V or even a dozen volts at this time, the UPS will automatically shut down immediately, and the voltage will immediately return to the original value after shutdown. Determine the battery is aging.

Cap nut: also called cap cap nut as the name implies is a hexagonal nut with a cap, the cap
Its role is to fasten the outer part of the exposed cap, to prevent moisture or other corrosive substances
This prevents moisture or other corrosive substances from entering the inside, thus playing the role of rust prevention, thus improving its own and the use of the connection time.
