## Questions & Answers

**Q: Would the GB20 start a 2l Diesel engine?i know it says not recommended for diesel, but why?**
A: To answer the "why" part of your question, diesel engines have a much higher cylinder compression ratio, often reaching 18:1, compared to a petrol engine of around 12:1.  This requires a higher torque from the starter motor to crank the engine, which itself draws more current from the battery.  Also, the glow plugs in a diesel draw current to heat up, so this adds a little more to the drain on a battery.

**Q: How long does it hold its charge for?**
A: It is rated to hold up to 70% charge for over 1 year.

**Q: Can I use this to jump start a Toyota Prius (hybrid)?**
A: I also used this with great success on my Toyota CH-R 2.0 litre Hybrid

**Q: Is this unit a potential fire hazard if carried in top box or other compartments on a motorbike.**
A: Only if you break the case and expose the battery. Not an easy thing to do.
