Frequently Asked Questions
What is a Thumper Battery?
Thumper Battery range is designed to take the place of, or even work
alongside a dual battery system in the vehicle, boat etc. They are the
perfect option for those who either have no space for a traditional dual
battery system or would like to have the freedom of a portable dual
battery system that can be easily separated from the vehicle with a
massive spike protected jumpstarting capability.
commonly used for powering 12 volt refrigerators & lighting
although the applications stretch only as far as your imagination.
What Type of Batteries are used in the Thumper Battery Range?
Thumper Battery unit consists of multiple 12 Volt AGM cells (Absorbed
Glass Matt) linked together in parallel for the super fast recharge
time. The batteries are 100% maintenance free and will not leak or gas
when charging; perfect for use inside the vehicle or enclosed areas. The
AGM batteries allow for not only deep cycling but they additionally
allow for the massive cranking ability. The cells like to charge at a
voltage rate between 13 - 14 Volts, which means that they are fully
capable of charging via the supplied vehicle charging kit. Your Thumper
Battery unit is completely recharged before delivery.
condition of the cells can be checked by pressing the push button on the
front of the unit to illuminate the blue LCD display gauge.
Cross-reference the gauge against the voltage readings on the sticker
above to determine the remaining voltage available. The gauge has an
extremely low power draw and can be left on if require to monitor the
Thumper Batteries condition. If left illuminated the gauge will draw
approx 1 Amp over a 14 day period.
Will they leak or spill?
The AGM batteries completely sealed batterys, meaning that you will not
have to worry about the cells leaking acid, fuses, gases or any nasty
odours. Due to the fact the batteries are completely sealed, it allows
for the batteries to be stored on any one of their sides even
upside-down while working to full efficiency!
Can I store the unit in a non-ventilated area, such as under a bed?
Considering that the batteries are completely sealed it means that the
batteries do not require a ventilated area for storage. This results in
the perfect battery to have stored in an out of the way area such as
under a bed in a caravan or under a vehicle's seat, even in a draw in
the back of 4WD!
Do the batteries hold a memory?
many batteries on the market, the Thumper Battery does not hold a
"memory", which means that at any stage, regardless of the state of
charge the Thumper Battery may be recharged or discharged, without
affecting the life of the unit which is approximately 5-7 years after
which the units can be re-packed and given a brand new 2 year warranty.
In Vehicle Charging!
All units are supplied with a Complete Charging System for the vehicle or boat, which when installed correctly, will allow for a
time of 2 â 3 hours and never let your vehicles starting battery go
flat as it automatically separates the Thumper Battery from the starting
battery when the motor is not running.Your Thumper Battery will
be supplied with a 20 Amp In Vehicle Charging System. The charging kit
is designed to be hard mounted into the vehicle and when installed
correctly; this kit will provide a charge rate of up to 20 Amps
depending on the unit's requirements and the vehicle's alternator.Your
Thumper Battery can be continuously connected to the vehicle charging
kit without risk whilst simultaneously providing power for on-board
accessories (for example â car fridge) if desired.
(We do not recommend charging the unit straight from a vehicle's cigarette socket, as the unit will never reach full charge)
Can I charge my unit and discharge it at the same time?
This is the perfect way to use your Thumper Battery. All connections on
the Thumper Battery may be used for recharging or discharging.
Charging from a 240v Source
Thumper Battery can be charged from 240 Volt; however, the charger MUST
be regulated or automatic to ensure that the cells are not damaged if
accidentally left for extended periods. Chargers should not exceed 14.8
volts as this will result in damage to the cells and will void the
warranty of your Thumper Battery Pack.
A 240volt to 12 volt power supply to run your fridge is not a suitable device for charging.
connect the alligator clamps of your regulated or automatic charger to
the Thumper Battery via the 175Amp Anderson connector (Positive to the
positive terminal, negative to the negative terminal).
apple power packs are considered flat at a voltage of 10.5Volts. When
recharging via 240Volt, the charger should have the ability to fully
recharge the unit within 25-30 hours. Longer periods of charging will
not result in better performance and may result in damage to the cells,
which will affect your warranty.
For an accurate reading of your
Thumper Batteries state of charge, wait for 30 minutes after
disconnecting from the charger as this will allow time for any "surface charge" to fade.
Can I recharge my unit straight from my generator?YES!
We recommend putting a regulated battery charger between the generator
and your unit for a faster recharge and to protect you batteries from
the spikes that can occur with Generators charge outputs.
Can I use Solar Panels to charge my unit?
Solar panels can be used for charging and/or maintaining the Thumper
Battery packs. Keep in mind that solar panels that are rated at 10 watts
or higher must be regulated when connected to any type of battery. This
will prevent the solar panel from over-charging the battery and
potentially causing damage. We also sell solar panels, check the our
Using your Thumper Battery
Will it run my fridge?
Yes it will and many other appliances also!
of the main accessories in which people use with the Thumper Batteries
are 12/240Volt compressor type fridges. As the batteries are deep cycle
it allows for the running of accessories even while the battery is
charging through vehicle charging, Solar or even 240 Volt!
We do not recommend running gas fridges for prolonged durations due to the high power draw (approx 12 + Amps per hour).
Can I use inverters for 240 Volt appliances?
We now offer a range of Inverters which allows the units 12 Volt power
to be converted into 240 Volts for the running of 240Volt appliances.
Inverters come in a variety of sizes ranging from 150 watts at 240 Volts
through to 3000 watts or more. These units will allow for the running
of appliances such a laptop computers, recharging phone and camera
batteries to even running TV's, DVD players or even powering tools such
as drills and 4 inch angle grinders!
How long will the battery last while running my appliances?
duration of time that the Thumper Battery will last with running
accessories such as a fridge largely depends on the amp draw of the
appliance in question. For example: a fridge with an average draw of 1
amp per hour would run for 30 hours with a 30 amp hour unit.
What is an Amp Hour?
hour is the rated capacity of the unit. If a unit holds 60 AH and you
discharged the unit using a fluorescent light that draws 1 Amp per hour
the unit would last for a duration of 60 hours before needing
What size Thumper Battery do I need?
out the size you need simply multiply the average amp per hour draw of
your fridge by the amount of hours you want your fridge to run for. Take
into account that if you are driving a little every day your unit will
be recharging i.e 1 hour of driving you will have put 25% charge back
into your Thumper Battery.
What is the life expectancy of the batteries used?
AGM cells used in the Thumper Battery range have a life expectancy
between 5 - 9 years. The life of the Thumper Battery range largely
depends on the method in which the unit is charged.
10 years on the market has proved that the life expectancy of the units
increase when the units are charged via the provided In car charging
kit. When the unit is not in use (discharged regularly), the best method
of maintaining the Thumper Battery is leaving the unit connected to its
In Car kit. This maintains the battery and aids in prolonging the life
of the cells used in the battery pack.
What is the warranty of the Thumper?
The Thumper offers a 2-year warranty from the date of your purchase.
What do I do when my cells in my unit die?
Although the Thumper Battery range offers a 2 year warranty and has a life expectancy between 5 - 9 years.
We offer our customers the chance to have their unit repacked when the cells do eventually die out!
a customer has paid for a repack we offer our customers a new 2-year
manufacturer warranty on the unit from the date of repack.
