  • HRL stands for High Rate and long life. The series focus on improving trickle life that base on HR series. Main features as follow:


    •    When it is used in safe surroundings, the battery is maintenance free, adding water is unnecessary and it can be recharged repeatedly.
    •    With isolated seal, it can be put in horizontal way, vertical way and side way, its safety and functions totally will not be affected.
    •    With special formula to manufacture lead calcium alloy as well as automatic progresses, gassing will be less.
    •    Long life, low self-discharge rate and high reliability.
    •    It has safety, low resistance so recharge is easy and energy output is more remarkable.
    •    Container material could be frame retardant ABS or PP with ranking UL 94V-0 by model.
    •    Standby use.
    •    High rate discharge construction.
    •    Deep discharge recoverability.
    •    Batteries are strictly tested by our patented computer charge/discharge system.
    •    ISO9001, 14001, OHSMS 18001 certified.
    •    UL recognized components under UL 1989 (file number MH14533).
    •    Complies with IATA/ICAO Special Provision A67 for air transport.
    •    Classified per MG Amendment 27 as a non-hazardous material for water transport.
    •    Recognized by DOT as "Dry charge" 49 CFR 171-189 for surface transport.
