How to use

Install the BLOW 12V 20Ah battery in accordance with the UPS or device manufacturer’s instructions, observing correct polarity and secure terminal connections. Verify that the charging source and charger settings match the battery type and voltage to ensure proper float and cycle charging profiles. Allow the battery to reach ambient temperature before charging if it has been stored in a cold environment. After installation, perform an initial charge and periodic checks of voltage and load to confirm reliable operation.

Usage recommendations

Store and operate the battery within recommended temperature ranges to maximize service life; avoid prolonged exposure to high temperatures. Use a charger compatible with sealed gel batteries and configure float charging at manufacturer-recommended voltages. For backup systems, perform regular status checks and replace batteries that show reduced capacity or signs of deterioration. Dispose of end-of-life batteries through approved recycling channels.
