is still needed to maintain the best condition and reliability.

faceplate of the readout;
b) Prevent any liquid entering into the connection ports on the panel.

correctly, the life of the battery will be shortened unless the following steps are taken:
a)
The new battery is undercharged, and only about 20% of the rated volume. The
new readout box can be used at once without charging but must be charged
immediately when the following display appears “
The
Voltage is not enough; Please
Charge
”
.
b) The first-time charge should be longer than 48 hours. Then at least
24hours. when charged for 24 hours, the battery will be charged to 80%, and be full
for 48hours operation.
