Specifications

HTB SeriesGFM-300HT 2V300AhSacred Sun HTB VRLA battery uses latest AGM technology designed for high temperature resistant performance with good cycle life and fast charging acceptance ability. Its average temperature can be 35-40℃. HTB's reduced needs for cooling saves energy and reduces cost. It is suitable for high temperature environments both in floating and cyclic applications. Sacred Sun has two ranges: 12V front terminal and 2V top terminal.

Standards ● JIS C8704-1● JIS C8704-2● IEC 60896-21/22● IEC 61427● EUROBAT guide● Installation compliant with EN50272-2
