should I buy a sealed motorcycle battery from YASAI MF
Batteries and not a conventional "flooded" motorcycle
battery from somebody else?
YASAI Batteries sells only premium sealed and
maintenance-free batteries. This is our specialty and
the only products we carry. We firmly believe that sealed
motorcycle batteries offer you, the motorcycle rider,
obvious advantages and long term value over lesser quality
is a sealed motorcycle battery better than a conventional
Our sealed motorcycle batteries feature Absorbed Glass Mat
improves a battery's performance in the following areas:
sealed and maintenance-free design, you will never have
to check or add electrolyte again, unlike conventional batteries
which require periodic fluid checks.
Liquid-free AGM design, will not leak or corrode on expensive
paint and chrome, and also eliminates corrosion around the
AGM batteries have less internal resistance which allows
them to produce more discharge current (cold cranking amperage)
vs. comparable conventional "wet" batteries,and
AGM batteries also recharge faster
Better resistance to both heat and vibration, a major cause
of failure in conventional motorcycle batteries
Much slower self-discharge rate, (3% vs.15% per month) means
longer periods between battery recharging over periods of
non-use, like winter months or vacations.
I expect longer service life from a sealed battery?
Yes, due to their sealed design, AGM batteries eliminate
water loss due to heat and evaporation. Most people
do not check their conventional battery's water level
on a regular basis, and as the electrolyte level in
the battery goes down, sulphation begins, which will
dramatically shorten a conventional battery's life.
Also the AGM battery's "Tight pack" lead calcium
construction provides better resistance to vibration,
there by by increasing it's service life.
sealed AGM motorcycle batteries require special charging?
No, most AGM motorcycle batteries can use the same low
amp battery chargers that conventional motorcycle batteries
use. We recommend a 1-2 amp "Smart" style charger,
which will charge only to a certain point then taper down
and maintain the battery safely for long periods. Check
with the battery manufacturer or reseller on your particular
battery's charging requirements.
sealed batteries safe?
Actually sealed AGM batteries are safer the conventional
wet or flooded motorcycle batteries. The AGM design
incorporates special safety valves in the battery case,
which are designed to prevent pressure build up inside
the battery during periods of excess over charging.
happens if I open a sealed battery's case?
By opening a sealed battery's case, you release a set
internal pressure or psi, which is crucial in a AGM recombination
design. In compromising the case you are dramatically
shortening it's service life and voiding the battery's
due I check a sealed battery's voltage?
Due to the fact that an AGM battery has a sealed case,
all you need is a volt meter to read it's voltage. A fully
charged AGM battery's voltage should read about 12.7 volts.
