What is a 12 Volt Battery?

UPS is called uninterruptible power supply, because it can quickly switch to the "inverter" state when there is a power failure, so that the computer in use will not lose important files due to sudden power failure and future storage. It is not used as a backup power source. If you just want to use electricity during a power outage, it is enough to buy an inverter. Most of the household UPS used are maintenance-free lead-acid batteries.

UPS battery

Even if the UPS uses the same battery technology, the battery life of different manufacturers is very different. This is important to users because the cost of replacing the battery is very high (about 30% of the price of the UPS). Battery failure will decrease

For a spare battery, after the battery is powered, the time required to recharge the battery is generally not less than 24 hours. For a cycle battery, if you know the last discharge amount and initial charge current, you can press The following formula calculates the charging time required when the environment is 25 ° C.

A. When the discharge current is greater than 0.25C

Cdis

Tch = I +3 to 5

B. When the discharge current is less than 0.25C

Cdis

Tch = I +6 to 10

Note: Tch = time required to fully charge the battery (hours)

Cdis = last charge of the battery (Ah)

I = maximum initial charge current (amps)

1. Calculating the battery

1. Over-discharge (over discharge): continue to discharge after the battery's specified termination voltage.
