The new BikeMaster's TruGel battery uses a
unique gel electrolyte that provides higher cranking amps, lasts
twice as long as conventional batteries, resists vibration, is
non-spillable even if the battery is cracked, and operates in any
position. The BikeMaster TruGel battery also comes with a 2 year
The BikeMaster TruGel battery
combines all the latest battery technology into one battery that
is stronger, safer and more durable. The true gel electrolyte
does not slosh around, leak, seep or evaporate. These batteries
have been observed to continue working spill free even after a
hole was drilled into the case! The gel based electrolyte is
more vibration and shock resistant which makes it safer and
better or vibration prone V-twins and/or extreme conditions.
Since sulfides and other elements are held in place by the gel,
the chances of settling, acid stratification and sulfation is
reduced dramatically. The gel in these batteries also offer
better performance in more extreme temperatures. The increase in
performance and range of these batteries will likely surpass
your willingness to ride in such extreme temperatures. Noted
performance increases have been observed from -40F to 122F!

TruGel Battery 101
BikeMaster TruGel Battery 101
BikeMaster has been working with the factory on this technology
for years, and in fact they developed the first gel motorcycle
battery in the world in 2004. Since then, there has been a
tremendous amount of research and development, with a lot of
refinement to make these batteries function with the variability
of motorcycle charging systems... After all, we are asking for
the battery to live in very different worlds... Some motorcycles
sit for months without use and this does its own damage to the
battery. Others are asked to tolerate up to 14.7 volts (the
highest output of the charging systems when the engine is
turning high revolutions...) for extended periods. This means
that the battery must be very tolerant of over charging, under
charging, high temperatures, low temperatures, high frequency
vibration, low frequency vibration, high G impacts (Off Road and
ATV), and everything in between.
So, how does the BikeMaster TruGel battery meet all these myriad
challenges? And if you could design a better battery, what would
you want it to do?
You would want it to be durable, and survive the pounding and
vibration of on and off road use in motorcycles and ATVs... And
this is one of the areas where a BikeMaster TruGel battery
really excels. TruGel Electrolyte with Nano-Gel Technology,
because of its viscosity, will not flow nor leakage, and makes
batteries safer than ever before. Even if the outer case were to
crack, the Nano-Gel would not leak like a regular water acid
based battery. In fact, we've seen these batteries continue to
function with no apparent reduction in ability with holes
drilled into the case!!!
Deep Cycling is where the battery is discharged deeply, and then
recharged again. You need a battery with the ability to recover
from extended discharges time and again. You would also want the
battery to survive long periods of inactivity, something that
has been a KILLER of standard (wet) water based batteries...
This is due to the fact that over time, the acid in the battery
suffers from stratification. This is caused by "precipitation"
of the sulfides in the liquid (they form crystals adhering to
the plates, and building resistance), thus causing Sulfation of
the Negative Plates, and Corrosion of the Positive Plates,
leading to the DEATH of the battery. This also leaves the liquid
in the battery in a weakened state, almost back to being
water... Thus there will be very little electricity generated in
the top "Weak Acid Zone", and very little charge generated in
the "Sulfated Zone". And when you add in the evaporation of
water from a standard battery over time... Well, what you get is
a battery that barely has enough charge to light the dash
lights... And will only make the starter solenoid "click"
without sufficient current (cranking amps) to start the engine
(We know you have been there! :-)))
But, because Nano-Gel Electrolyte is very high in viscosity, the
sulfides are "rigidly" held in suspension, and therefore acid
stratification will not occur to the same extent, hence we can
avoid the Sulfation to the negative plates and corrosion to the
positive plates (at the bottom of the plates due to high acid
specific gravity). Because the battery maintains 100% acid
concentration, in 100% of the electrolyte, 100% of the time, the
ability to use all of the electrolyte and plate surfaces, not
only increase the efficiency of the battery when new, but will
increase it's ability compared to a standard water battery, AND
result in a very much extend battery life span.
Obviously, you would also want a battery that functions well in
the cold environments of the North of our country... And
BikeMaster TruGel Batteries perform very well in a cold
environments, the battery working limit has been extended to
-40ºC (-40ºF). Far colder than anyone we know wants to ride!
:-))) Except for my snowmobile buddies in the Great White
Likewise, you would also want a battery that functions well in
extreme heat too... Which here in Texas is a necessity. Again, a
BikeMaster TruGel Battery by its very nature performs very well
in a hot environment. Even in an environment with 50ºC (122ºF),
the life span of a Bike Master TruGel Battery is double that of
a conventional water battery.
Because of the above mentioned efficient utilization of the
electrolyte and plates, the capacity of the battery is
increased. Looking at the performance curves, the fall off of
the performance is much extended. This is especially true at the
later stages of the standard water battery's life, where the
capacity is lowered dramatically by the loss of fluid due to
evaporation in the hot environment. Therefore, the BikeMaster
TruGel Battery gives not just a longer life, but a higher
plateau for longer in working capacity overall, but especially
so in high temperatures.
Self Discharge Rate:
You also want a battery that when not used frequently has a low
self discharge rate. Again, BikeMaster TruGel batteries excel in
this area. Because Nano-Gel Electrolyte will help to reduce the
rate of negative plates sulfation, and therefore greatly reduces
the battery self discharge rate, hence it will increase the
shelf life, extending it far beyond that of a standard water
battery... In fact, the battery will be able to start a
motorcycle after one year (or more) sitting on the shelf. This
will be a huge advantage for dealers, who can order and not
worry about having to constantly keep their inventory charged,
or order less, or have dead batteries... It's an advantage for
Tucker Rocky as a distributor, in that they can ship batteries
with far more confidence, and order quantities that make sense
for them, not based on shelf life. AND, it's an advantage for
the customer, who can buy with confidence knowing that the
battery will have the power, and a life span that will far
exceed the other batteries he has purchased and replaced time
and time again, that are based on water...
Can I get a bit technical here? Would you like to hear about
recombination? Of course you would! :-)))))
A standard lead-acid battery is an electrical storage device
that uses a reversible chemical reaction to store energy. It
uses a combination of lead and lead oxide plates or grids, and
an electrolyte consisting of a diluted sulfuric acid (H2SO4, @
about 35% concentration) to convert electrical energy into
potential chemical energy and back again. It does this because
when the two plates (the lead and the lead oxide) are immersed
into the acid solution, two things happen. One, the lead plate
is forced to release protons into the electrolyte, and this
leaves it in an electron rich state, or negatively charged. Two,
the lead oxide plate is forced to release electrons into the
electrolyte, and this ends up with more protons, and this is
positively charged. When you connect a load to the battery, say
a starter, the electrons from the negative (lead) plate try to
rush over to the positive plate (lead oxide) to balance the
The loading of the battery and this flow of elections causes the
formation of lead sulfate in the electrolyte, which is deposited
on the plate surfaces (almost like a Sulfate Electro Plating).
The "ate" in sulfate is oxygen which is stripped from the water
in the electrolyte, and once stripped from the water, it leaves
free Hydrogen as a gas to escape from the battery... So, when
you apply a charging current to the battery you reverse all this
process, and the result is that you need oxygen to "recombine"
with the hydrogen. All of this to say that...
Because TruGel Nano-Gel Electrolyte has a "three dimensional"
lattice structure (because the gel is made using Silica to
stiffen it, which has a "lattice structure", during the charging
process, it will guide the generated oxygen horizontally toward
the negative plates where the recombination process occurs with
the generated hydrogen, which in turn reduces the moisture loss,
and increases the sealed performance, and thus battery life.
Hope this helps,
