Product Description

LONGWAY 2V500AH/10HR Long Life Battery FM500G

2V500ah Long Life Rechargeable Storage 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.

Longway lead acid battery1)Reliably sealed construction 2)extra long duration time at low rate discharge.
