Product Description

LONGWAY Long life batter Valve Regulated Battery 2V500ah

2V500ah Long Life Valve Regulated Battery

LONG WAY Long Life Battery Series (D series) battery is specially designed for long service life in standby applications.
The D series batteries are float charged at a constant voltage and constant current during the application. The floating charge will make up for the capacity because of the self discharge. D series batteries will performance when the main power is off. D series batteries should be kept float charged during its service life. Ensure the stand by applications for the D series batteries.
