The CooPower sealed lead-acid rechargeable batteries (VRLA) are
leak-proof and maintenance free. The superiority of our batteries is
derived from its uniquely efficient oxygen recombination technology.
The oxygen evolved from the positive plates diffuses through the
micro porous glass fiber mat to the negative plates where it is
changed back to water by a recombination reaction, eliminating the
need for the addition of water .The result is not only a maintenance
free battery, but also a product chock full of other benefits. This
saves you troublesome maintenance costs.
， [ No Free Acid ] All of the
electrolytes are absorbed into the positive plates, negative plates,
and the micro porous glass fiber mat. There is no free acid inside
the battery, therefore the VRLA battery can be mounted in any
， [ Safe and Sealed ]
construction and sealing technology ensure that no electrolyte
leakage can occur from the terminals or cases of any VRLA batteries.
， [ Maintenance-Free Operation ]
During the expected service life, there is no need to check the
specific gravity of electrolyte or to add water.
， [ No Corrosive Gas Generation ]
There is no corrosive gas generation during normal usage, as gas
generation during over-charge is recombined in an unique "oxygen
Pressure-Venting System ] VRLA batteries are equipped with a
safe, low pressure venting system, which automatically releases
excess gas in the event that gas pressure rises to a level above the
normal rate, thus ensuring no excessive build-up of gas in the
batteries. Resealing is automatic once the pressure is returned to
， [ Long Service Life ]
of heavy-duty lead-calcium alloy grids with anti-corrosive
construction enables the CooPower VRLA Batteries to remain in float
service about 5 years (6V, 12V series) and above 10 years (2V
series), or expect between 250-1000 charge/discharge cycles
depending on the average depth of discharge.
， [ Long Shelf Life ] At an
environmental temperature of 25≧(77F), the self-discharge rate of
VRLA batteries is only 3% -(approx.) of the rated capacity per
month. Lower storage temperature enhances shelf life characteristics
， [ High Discharge Recovery ]
Special separators, advanced plate composition, and a carefully
balanced electrolyte system have greatly improved the ability of
batteries to recover from excessively deep discharges.
， [ High Quality and High
Reliability ] The CooPower VRLA battery has stable and reliable
capacity. It withstands overcharging, over discharging, vibration,
and shock. Our batteries are 100% tested on line for voltage,
capacity, and seals.
， [ High Power Density]
VRLA Batteries save installation space, while providing full and
reliable power. Many have been designed for high power output.
