It is very important that proper charging techniques be used when charging AGM batteries. AGM
batteries are designed for use with AGM battery chargers with a MAXIMUM output voltage of 2.4 volts per
cell(14.4v for 12v batteries and 19.2v for 16v batteries). AT NO TIME during charging should the battery be
subjected to more than 2.4 volts per cell. Voltage above this will cause the battery to “gas” and once
oxygen is vented it cannot be restored.
Under-charging AGM batteries is equally damaging to the life of the battery. Take special care to ensure
that the battery is properly charged before the initial use by verifying the open curcuit voltage is above 2.1
volts per cell(12.6v for 12v batteries,14.7v for 14v batteries, and 16.8v for 16v batteries). Improper
charging can cause damage that is permanent and WILL VOID THE WARRANTY.
XS Power 12-Volt AGM Batteries
The XS Power 12-Volt AGM Performance battery is a six cell, sealed-valve regulated, lead-acid battery.
Sealed-valve regulated, lead- acid(VRLA) batteries are manufactured in two types, gel-cell and
AGM(Absorbent Glass Mat). The key difference is how the electrolyte is suspended between the lead
plates. AGM batteries such as the XS Power 12-Volt AGM Performance Batteries, use a fibrous material
to suspend all liquid electrolyte against the plates. Even if the case were ruptured, no acid would leak. In
contrast, gel-cell batteries suspend the electrolyte in a gel form and are not necessarily leakproof.
AGM batteries are similar in chemical function to flooded and maintenance free batteries in that
they convert electrical energy into chemical reactions on the lead plates. AGM batteries differ in the
amount of electrolyte used. AGM batteries have substantially less electrolyte than a typical flooded or
maintenance free battery. Operating with less acid is possible in an AGM battery because each cell in the
battery operates on a slight positive air pressure. This air pressure allows for the water produced
during discharge to condensate and therefore recycle inside the battery. Hence almost no gasses escape
the battery under proper charging conditions. If the battery were to be overcharged, the small amount of
electrolytes could be “gassed” and vented by means of the safety valves from the battery. This is
the main cause of premature AGM battery failure and therefore should be avoided. The cells are
compressed before insertion into the case, which increases performance and makes the battery
extremely vibration resistant. The reduced acid content of the battery allows for additional plates and
therefore additional performance in an AGM design. XS Power is using this unsurpassed technology to
bring high performance to the 12-Volt audio, motorcycle, marine, commercial and automotive markets.
Proper Charging Is Crucial! Charge Before Initial use!
WARNING/SAFETY Precautions
Caution:
Do not overcharge this battery. Use only a voltage limited automatic battery
charger set at 14.4VDC±.3VDC maximum.
This is a sealed battery. Do not attempt to remove the vent caps under the top
label.
Recycle used batteries in accordance with local, state, and federal law at an
authorized recycling center.
Battery must be recycled!
Care of XS Power 12-V AGM Battery
Charge voltage is not to exceed 14.4V total for extended periods of time.(5min. max)*
The charger used MUST HAVE an automatic shut-off.
*Some AGM chargers may climb to a maximum voltage of 15.5VDC for a short period of time(usually less than
5min.) but will resume charging at or near 14.4VDC±.3VDC for the duration of the charge cycle. If you are
unsure of your chargers capabilities, contact the manufacturer of the charger
Exceeding 14.4VDC±.3VDC will cause the battery to “gas” and once the oxygen is released from the
battery there is no way to restore it. The results will be reduced capacity and battery life and those results
are permanent. This type of damage will cause the battery to show a proper open circuit voltage yet will not
accept a charge and will become excessively hot during charging. Damage of this nature will void the
warranty. Therefore ensure that your battery charger will not exceed 14.4VDC±.3VDC at any time during
the charging cycle. For ease of use, we recommend recharging the battery with an XS Power
IntelliCHARGER p/n 1005, as it is a totally automatic 3 stage microprocessor controlled battery charger
with float charging capability. This battery charger prevents overcharging, maintains proper performance
and can be left on the battery indefinitely during non-use periods.
It is very important to
NEVER USE
a charger designed for flooded 12V batteries, not even once with a
XS
Power 12V AGM battery
. Furthermore, we recommend that the battery be disconnected from the rest of
the vehicle’s electrical system during charging.
“Off Season” Maintenance
All lead-acid batteries, both flooded and AGM designs are subject to self-discharging and this
self-discharge rate is very much affected by ambient temperature in which the batteries are stored. Higher
ambient temperatures will discharge the battery faster. Cool storage for batteries is the best. When voltage
is lower than 12.6V or storing time is longer than 6 months, the battery must be recharged as described in
the Preformance Curve diagram to the left.
Warning:
Lead-acid batteries of all designs produce explosive gasses. Sparks of any kind could cause a
battery to explode.
Therefore:
Never smoke when around a battery.
Never weld or otherwise produce sparks around a battery.
Do not allow tools or other metal objects to fall across the battery terminals- this will short circuit
the battery.
Always wear protective clothing and eye wear when servicing a battery.
Sulfuric acid can cause severe burns. If acid comes into contact with your skin flush with water
immediately. If acid comes in contact with your eyes, flush immediately with water for fifteen
minutes and seek medical help promtly.
Neutralize acid spills with baking soda and water.
Keep all batteries out of reach of children.
California Proposition 65 Warning: Batteries, battery posts, terminals, and related accessories
contain lead and lead compounds, and other chemicals known to the State of California to cause
cancer, birth defects, and reproductive harm.
Wash hands after handling!
