I have a car I drive every day and a second one that stays in the shed most of the time. How often should I drive the second car to make sure its battery doesn’t go flat?Answer

If you are unable to drive your second vehicle regularly, at least a couple of times a week, you may want to invest in a charger for the vehicle.

You can buy a maintenance charger that will trickle a charge into the battery to keep it at 12 volts and in good condition.

We would recommend talking to your local auto electrician and have them supply you with the correct unit, as without this you will eventually have a dead battery.

Most modern vehicles draw a small amount of power from the battery when the vehicle is turned off. Batteries also have a natural self-discharge.

Short trips, stop-start driving, night driving and hot or cold weather all take their toll on batteries; even disconnecting the battery will only delay the inevitable.Question

I like setting my mirrors so I can see the sides of my car, but I’ve heard this can exaggerate blind spots. Is there a right and wrong way to do this?Answer

Mirror adjustment and seating position is something people quite often get very wrong.

If you do a driver training course, the first thing they will teach you is how to sit correctly and how to properly adjust your mirrors.

Having your mirrors adjusted so you can see the sides of your vehicle usually leaves you with large blind spots.

Instead, adjust the side-mirror viewing angle outward until you can see an overtaking vehicle just overlap your rear-view mirror into your side mirror (do this for both sides). You should not be able to lose sight of a vehicle alongside you between both your rear-view and side mirror when adjusted correctly.

This can take a bit of getting used to when you have had the mirrors adjusted so you can see the side of your vehicle, but it works and makes a big difference.
