Frequently Asked Questions
Is a Batteryless Jump Starter safe for a car’s ECU computer?
Yes. Batteryless Jump Starters use super-capacitors instead of a battery. The voltage of the capacitors are
restricted within the safe range of all kinds of ECU’s, so there is no risk from over-voltage damage. Capacitors have
a very small charge, approx. 0.2 - 0.4 Ah. Disconnecting the Batteryless Jump Starter will not cause any high load
dump, so there is no damaging voltage spike.
Most ECU jump start damage is caused by the following reasons:
1. Jump starting Car to Car - Not all modern cars have compatible charging systems and may cause damage to
one or both if linked during a jump starting procedure.
2. Jump Starting with a booster pack or other battery - When a car is started by a booster pack or donor car’s
battery, the alternator will start to recharge both batteries after the engine has started. When the booster
pack is disconnected from the car, the power produced by the alternator is much more than what the cars
battery can absorb, thus pushing up the voltage. Transient voltage spikes can reach 25 - 100V, which can
easily damage the ECU.
What is Bypass mode?
The ECU of some cars doesn’t allow the engine to start if the batteries voltage is lower than 8V. In this situation, the
positive battery lead needs to be disconnected from the car battery and connected directly to the Positive Battery
Clamp RED (1). When connected like this the vehicle battery is “by-passed” (Bypass Mode). The ECU can then detect
the higher voltage provided by the Batteryless Jump Starter and allow the car to start.
How long can the Batteryless Jump Starter hold charge?
The Batteryless Jump Starter will hold a charge for one to two days. The period of charge storage is a NOT a critical
issue with your Batteryless Jump Starter as it can be rapidly charged from various power sources within minutes.
Does the Batteryless Jump Starter need to be regularly recharged?
No. Unlike a battery, capacitors do not require a shelf charge to stay functional, and therefore do NOT require
ongoing recharge maintenance. The Batteryless Jump Starter can be operational within minutes.
