Q. Will the transfer of residual energy to the jump starter damage the weak battery?
A. No. This jump starter draws only 0.2-0.4Ah energy from the battery. A weak car battery
normally has a capacity of 10-30Ah and can recharge the jump starter many times without
any adverse effects.
Q. How many jump starts can a fully recharged jump starter perform?
A. This jump starter is designed to start only once when fully recharged. It recharges itself after
each use, if left connected to a car's battery. Therefore, it can jump start many times as
needed, successively.
Q. How long can the jump starter hold a charge?
A. This jump starter will self-discharge to 0 in a few days, but it can be instantly recharged from a
weak battery or from the back-up lithium battery, and be ready for use.
Q. What is the life span of this jump starter?
A. This jump starter can be used more than 10,000 times before noticeable loss of performance.
Ultracapacitors remain operable for more than 10 years.
Q. Is my hybrid jump starter safe?
A. It is extremely safe. Ultracapacitor technology is one of the foremost advantages over the
battery-based jump starters. Ultracapacitors are specially designed to receive and release a
large electrical current of instant power.
This jump starter is also equipped with short circuit/reverse polarity protection. Therefore,
short circuit due to unintended use will not damage the ultracpacitors. They will not overheat
and cause fire or explosion.
NOTE: Reverse polarity and short circuit protection is disabled during Override Mode.
Q. Does the jump starter need to be regularly recharged?
A. No. The jump starter relies on the instant recharging of ultracapacitors rather than stored electric
energy. Therefore, it does not need regular recharge and can be stored for years. However, the
back-up lithium battery needs to be recharged at least once a year.
Q. What is OVERRIDE mode?
A. The ECU of some cars does not allow engine to start if battery's voltage is lower than 8V. In
this situation, the positive lead needs to be disconnected from the car battery, and instead
connected directly to the jump starter. Then the ECU can detect the high voltage provided by
the jump starter.
WARNING: CAREFULLY READ USER'S MANUAL BEFORE USING OVERRIDE MODE.
Q. What is GLOW?
A. In cold weather, the glow plugs in most diesel vehicles will energize first to heat up the engine
chamber before the engine start, as indicated by the GLOW sign on the dashboard. The
process needs a current of 40-60Amp and takes about 4-6 seconds. In this case, after the
jump starter is fully recharged and connected, press the GLOW button, and then turn on the
ignition.
Q. What size of engines can be used with this jump starter?
A. Success of a jump start depends on many factors such as battery condition, temperature, age of
the car, etc.
