5 Q 5 A explains how to maintain UPS battery (part 1)

1, the battery how to maintain normal life expectancy?

A: 1, normal, the battery every 3-6 months, the charge and discharge time, discharge time after charging standard unit of not less than 10 hours. Dell Inspiron 1318 battery Dell Inspiron 1320 battery

2 UPS long rest should be 3 to 6 months duration of load.

3, the battery life, ambient temperature between 0 ℃ to 40 ℃ requirements, avoid direct sunlight and clean.

4, the temperature generally less than normal use Panasonic sealed maintenance-free battery lead-acid float lifetime of 3-5 years.

2, UPS is able to use the battery with water?

A: Yes, but recommends the use of maintenance-free battery. As can occur in the use of water user password, batteries and battery acid gas Tangchu bad, and so on, causing cell necrosis or disrupt the normal functioning of the burden of UPS. In addition, the mountain is a special charger for the UPS lead-acid batteries designed features, it is not applicable to other types of batteries.

3, UPS will have the release form specific time?

A: Because the discharge time of battery discharge current, ambient temperature, the type of load, speed, battery capacity and numerous other factors related to the actual discharge time can not be directly deduced . Is to provide battery discharge maximum current equation: I = (Pcosφ) / (ηEi)

Where P is the rated output of UPS

Is the power factor of load, PC, server usually take 0.6 to 0.7;

UPS is the performance, usually 0.8 (Mountain Special 10KVA 0.85);

Ei is the end of the discharge voltage of the battery, usually refers to the voltage of the battery.

Specific data on the type, find the current maximum capacity of the battery, you can all temperatures of the battery discharge time and discharge current diagram to identify the corresponding discharge time. Please note that there is obtained the discharge of the battery the total current value. When the external battery when the multiple needs of a single set of battery discharge current value. fujitsu lifebook t4010 battery fujitsu lifebook t4010d battery
