longevity but at a lower price point. Yuasa manufactures
several designs of these batteries: Conventional (YuMicron)
and High Performance Conventional batteries (YuMicron CX).
They have features in common that Yuasa uses for all their
batteries. Sealed posts to resist corrosion, tough polypropylene
covers and containers and heat sealed construction for a
strong, bonded unit. In addition, they share design features,
like special separators and through-partition construction.
Yuasa YuMicron batteries have more cranking power (up to
30%) for their physical size than a standard Conventional
battery. The plate surface area in the YuMicron is increased
by the use of thin, high-tech separators that make room for
extra plates within each cell. The YuMicron batteries also use a
special inter-cell connector that minimizes internal resistance
and further maximizes starting capacity, plus a special glass
mat that resists vibration damage. The difference between
the YuMicron and the YuMicron CX is the material used in the
plates. Conventional and YuMicron batteries both use lead-
antimony plates while the YuMicron CX uses lead-calcium.
The use of lead-calcium technology provides increased cold
cranking amps, reduced water loss (up to
66% when compared
to a Conventional design) and has reduced self-discharge
properties resulting in a battery that will hold a charge longer.
Do all the features offered by the YuMicron design make
it a better choice than a Yuasa Conventional battery? Not
necessarily as it depends on the vehicle and application. While
a Conventional battery is an ideal choice for a lawn tractor
it may not be for an ATV, watercraft or motorcycle. Space

Yuasa batteries are also available as a dry battery with an acid
pack. The part numbers for these batteries end with “-BS” to
signify “bottle supplied” (i.e. YTX
14-BS, YTX20HL-BS). Because
the battery is shipped dry, it has an indefi nite shelf life before it
is activated as long as the foil covering the cells remains intact,
undamaged and air-tight.
Because AGM batteries are different than Conventional
batteries, it is important to keep these points in mind:
1. There are important differences in the activation
of an AGM battery versus a Conventional battery. Be
sure to follow the instructions for activating AGM batteries.
2. While Yuasa AGM batteries dramatically reduce
the need for maintenance, they do need periodic
charging. It’s important to remember this and use the
correct charging method and battery charger.
3. When considering upgrading to an AGM battery
that was not original equipment on a vehicle, check
to make sure the charging system has a regulated
output between
14.0 and 14.8 volts. In general, older
vehicles have a charging rate that produces lower voltages
and a Conventional battery will be the only battery option
for these vehicles.
Conventional Batteries
Unlike AGM batteries, Yuasa’s Conventional designs have fi ller
caps and vent tubes. Not all vehicles require an AGM battery
and the Conventional batteries offer good performance and
