There are many variables that need to be considered when trying to calculate the run times of fridges from a battery source. Factors such as fridge size, fridge temperature, ambient temperature, how empty/full your fridge is and how often you are in and out of the fridge all need to be taken into consideration when calculating approximate run times from a battery.
We at Home of 12 Volt allow for an approximate run time based on the above variables, however much better run times can be achieved. Thumper 48 AH Battery Pack - 40LT Fridge approx run time of 35 - 48 HOURS - 60LT Fridge approx run time of 30 - 48 HOURS
The above run times do not involve any recharge and are based on a continuous run time using the 12 Volt 40Lt / 60Lt compressor type fridge. Basic Questions and Answers
What is Thumper?
The Thumper 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 jump-starting capability. Most commonly used for
powering 12 volt refrigerators & lighting although the applications
stretch only as far as your imagination.
Is jump-starting my vehicle safe?
Yes! Jump starting with the Thumper range is perfectly safe for both
the unit and your vehicle. The Thumper range is completely spike
protected which means that you will not incur any of those nasty voltage
spikes which could potentially fry a vehicle's internal circuits and
cause you thousands of dollars in vehicle repairs.
Will the Thumper start my diesel?
Yes! Each of the Thumper units hold a differing CA output, which
means that the cranking ability varies between the sizes of each unit. Refer to specifications section for the cranking abilities of each Thumper model.
What Type of Batteries are used in the Thumper Range?
Each Thumper unit consists of multiple 12 Volt AGM cells (Absorbed
Glass Matt) linked together in parallel for the super fast recharge
time. The battery's 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 unit is completely recharged before delivery.
The 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’s condition. If left illuminated the gauge will draw approx
1 Amp over a 14 day period.
Will they leak or spill?
No. The AGM batteries completely sealed battery's, meaning that you
will not have to worry about the cells leaking acid, fuses, gases or any
nasty odors. 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?
Yes. 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?
Unlike many batteries on the market, the Thumper does not hold a
‘memory’, which means that at any stage, regardless of the state of
charge the Thumper 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 recharge time
of 2 – 4 hours and never let your vehicles starting battery go flat as
it automatically separates the Thumper from the starting battery when
the motor is not running.
Your Thumper 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
Your Thumper can be continuously connected to the vehicle charging kit
without risk whilst simultaneously providing power for on-board
accessories (for example – 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?
YES! This is the perfect way to use your Thumper. All connections on the Thumper may be used for recharging or discharging.
Charging from a 240v Source?
Your Thumper 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.
Simply connect the alligator clamps of your regulated or automatic
charger to the Thumper via the 175A Anderson connector (Positive to the
positive terminal, negative to the negative terminal).
For an accurate reading of your Thumper’s 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?
Yes. 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. See our wide range of panels
available from this store!
Will it run my fridge?
Yes. It will and many other appliances also! One of the main accessories
in which people use with the Thumpers 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?
Yes. The Getaway range includes an inbuilt inverter. 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?
The duration of time that the Thumper 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?
Amp 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 do I need?
To work 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 battery. Feel free to call us on for help
choosing the correct battery size on the number at the top of your
What is the life expectancy of the batteries used?
The AGM cells used in the Thumper range have a life expectancy
between 5 - 9 years. The life of the Thumper range largely depends on
the method in which the unit is charged. Over 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
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
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 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! Once 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.
Where and how are the Thumper units made?
The Thumper range is proudly South Australian made and owned. Each
unit is hand made from start to finish to produce the best portable dual
battery system with the highest cranking ability available on market!
