  • MAXMA 12V-18AH
  • Warranty 3 Months
  • AGM-12V18AH

AGM BATTERY BAT 5AH-18AH is the general purpose battery with 5 years design life for float service. It meets IEC and JIS standards. With up-dated AGM valve regulated technology and high purity raw materials, the RT series battery has reliable standby service life.

It is suitable for UPS/EPS, medical equipment, emergency light and security systems applications.


Capacity range : 1.3Ah – 28Ah

Voltage class : 6V/12V

Long design life (25C) : 5 years

Low self-discharge rate : < 3% /month

Good high rate discharge performance

High sealed reaction efficiency : > 99%

Wide operations temperature range : 20C ~ 60C

Structure : Compact design, shorter internal connectors between cells, thus low internal resistance

Plate : Pasted flat type, with patent formula of AM

Terminal: Two or more types terminals are convenient for selection

Separator : using improved AGM separator, makes lower resistance, higher assembling pressure to increase cycle life.

Battery case: made of high strength ABS (UL94-HB) and UL94-V0 is optional

Terminal sealing : double sealing techniques (mechanical + epoxy glue)


Small UPS

Emergency Light

Security System
