Tips how to "get a light" battery

One of the common problems of cars - the lack of battery power. If you are using to run an external source must comply with certain rules.

What wire for jump leads thicker - the better. Minimum cross-sectional area for cars with engine capacity of about 1,5 l - 16 square. mm (diameter about 4,5 mm), and the optimum - within 70 square. mm (diameter 9.5 mm). The latter is sufficient for most car models. Wire material - copper. Insulation needs a solid, but soft, not to "the double" and not crumbled in the cold, the best Silicone. Connect all wires with clips have to be on rations - a simple crimping enough. Up in the "Crocodile" is also not interfere with an insulating coating, and required sharp "teeth" for the best contact. What wire is shorter, the lower their resistance, so that half or two meters - the optimal length.

Make sure that the cars do not touch each other, turn off all energy consumers, turn off the ignition on both machines. First, we should connect the positive terminal: first attaches the cable to the positive terminal of the discharged battery, then the "minus" to "plus" charged. Then another cable first adjoin to "minus" a charged battery and a "mass" (not to the battery!) "Recipient". To do this, choose (if there is no special probe of "mass") unpainted part of the engine, maximum distance from the batteries, moving parts and fuel. Note: at the time of contact, a spark is inevitable!

Now run the engine "donor" and give it idle for at least two or three minutes, and better, and all ten: to operate a battery immediately begins to "suck" energy from a charged, so you need to be fueled generator. Before turning on the starter "recipient" has the sense to bring the momentum "donor" to mean - in most cases is about 2000. Before disconnecting let machines work for at least another three or four minutes. Photographing the wires must be in sequence, the reverse connection. To reduce the voltage jump on the "donor" before disconnecting the wires can include ventilation, for example, rear window. It is strictly not recommended at this time include lights: when voltage jump, they can burn out.

When it comes to "older" machines with electronic fuel injection control, for reducing the risk of damage to electronics from power surges before starting the "recipient" better to stifle "donor". But then there is the risk of "sucking up to the bottom of the" single charged battery.
