Description features:Features:
Stagnant acid: all of the electrolyte is sorbet in the exceeding thin fiberglass
clapboard and anode. It is stagnant acid. So McNair brand rechargeable Lead-Acid
can be placed and used discretionarily.Safety, seal: the unique structure and seal technique ensure no electrolyte overflow
from the port or the cover.SMF: do not check the electrolyte proportion or add water during the anticipative
life.No corrosive gas produced: the gas which is produced during the charging is compounded
by the oxygen. So no corrosive gas is produced during the normal use.Safe gas release valve door: McNair brand lead-acid batter uses low pressure safe
valve door. Valve door will open the door automatically when the pressure is too
strong after the false use, and then close automatically.Long life: the immune alloy to the corrosive and the structure of the alloy ensure
the life of the battery (6V - 12V, 3 - 5 years), (2V large battery: 10 years)
the cycle life is between 25~1000 according to the degree of the discharge.Low self-discharge: McNair lead-acid is low self-discharge depend on the high pure
materials. The losing of the battery is 3% per month under the 25 degree. Low
temperature can reduce the losing.Good instauration function: the advanced electrode and electrolyte materials improve
the instauration function.Strong reliability: the capacity of the McNair lead-acid is jarless after the over
charging, over discharging and jounce. The voltage, capacity and seal will be
all tested carefully before the shipment.High capacity: small cubage, high energy is the characteristic of McNair lead-acid
batteries, besides many is designed for the high energy output.border=0>
