What is a 12V 100AH UPS battery?

A UPS is called an uninterruptible power supply because in the event of a power failure it can be quickly converted to an inverter state so that important files are not lost when the computer is in use because of a sudden power failure and there is no time to store them. It is not intended to be used as a back-up power supply. If you just want to be able to use the power when the power goes out, an inverter is sufficient. Most of the batteries used in home UPS are maintenance-free lead-acid batteries.
The reason why an UpS (Uninterruptible Power Supply) can continue to supply power to computers and other equipment after a power failure is that it has a device inside that stores electrical energy, this storage device is the 12V 100AH UPS battery.

Main functions of the 12V 100AH UPS battery

1、When the mains power is normal, the electrical energy is converted into chemical energy and stored inside the battery.
2. When the mains power fails, the chemical energy is converted into electrical energy and supplied to the inverter or load.

The reliability of a 12V 100AH UPS battery is directly related to the reliability of the entire UpS system, yet the battery has the shortest mean time between failures (MTBF) of the entire UpS system. If the user is able to use and maintain the battery correctly, its service life can be prolonged, otherwise its service life will be significantly shortened, the battery type is generally divided into force lead-acid batteries, lead-acid maintenance-free batteries and nickel-cadmium batteries.

Taking into account the load conditions, usage environment, service life and cost, lead-acid maintenance-free batteries are generally chosen. Users should not choose inferior batteries for the sake of cheapness, as this will affect the reliability of the whole system and may result in greater losses.

12V 100AH UPS battery about charging

1. For float charging, please use a charging voltage of 2.275V/single cell (set value at 20C) for constant voltage charging or 0.002CA or less for constant current charging. When the temperature is below 0C or above 40C, it is necessary to correct the charging voltage by -3mv for each degree change in voltage per cell, starting at 20C. 2. For cyclic charging, charge at a constant voltage voltage with a charging voltage of 2.40-2.50V/single cell (set value at 20C). When charging at temperatures below 5C or above 35C, the charging voltage is adjusted by -4mv/single cell for each degree of change, starting at 20C.

The initial charge current is controlled at 0.25 CA or less. The charge volume is set at 100-120% of the discharge volume, except when the ambient temperature is below 5C, where it is set at 120-130%. The lower the temperature (below 5C) the longer it takes for charging to finish and the higher the temperature (above 35C) the more likely overcharging is to occur, so it is better to charge within 5C~30C especially when cycling. To prevent overcharging try to install a charging timer or automatically convert to trickle charging. The battery temperature should be kept within the range of -15C to +40C when charging.

The 12V 100AH UPS battery is to be discharged

Please keep the battery temperature within the range of -15C to +50C when discharging. Please keep the continuous discharge current below 3CA (H below 6CA). The discharge termination voltage varies according to the current, as described below. Be careful not to discharge at a voltage lower than the following. After discharging, recharge quickly. If you accidentally over discharge, recharge immediately.
