German VMF battery DC42-12 12V42AH maintenance free communication UPS power supply

Features of VMF battery products:

☆ Designed float charging service life of 8 years;

☆ Adopting lead calcium aluminum multi-element alloy;

☆ Adopting gas recombination technology, no water needs to be added during use;

At 25 degrees Celsius, the charged battery is charged at 0.1 degrees Celsius for 48 hours without any leakage or deformation in appearance.

To monitor the battery condition, the following checks should be conducted regularly on the battery:

1. Check for any loose, corroded, or damaged connections between batteries and between battery packs and DC power sources, and repair as necessary.

2. Check for any abnormal phenomena such as damage or leakage in the battery, and replace it if necessary.

3. Check whether the charging voltage and discharging capacity of each battery are within the normal range, and if necessary, perform charge discharge cycle testing on the battery.

Precautions for using batteries:

1. Batteries with different capacities, performance, manufacturers, and levels of age cannot be mixed.

2. During installation, use, and maintenance, insulated tools should be used and insulated gloves should be worn to prevent electric shock and short circuits.

3. When there is an abnormality in the battery, it should be handled by professionals or contacted by the manufacturer. It is prohibited to disassemble and repair it without authorization.

4. The product should be charged on a dedicated charging system

5. Do not use organic solvents such as gasoline and diluents to clean the battery, otherwise it may damage the battery casing.

6: Long term overcharging can shorten the battery life. Long term low charging (insufficient) can affect load operation or cause abnormal voltage.
