Get A Set Of Jumper Cables
Make sure to carry a set of jumper cables in your car at all times, just in case you end up needing them. Any set will do the job, but we suggest looking for cables gauge 4 to 6 in size, with a length of 10 to 20 feet. Cables of that size should be durable enough to work reliably, and a relatively long length gives you an added degree of flexibility in case you cant park another car right next to the one being jumped. You dont want cables that are too long, though, as the extra distance electricity has to travel may decrease the strength of the charge.
Portable jump-starters work, too, but the batteries that power them must be kept charged in order for them to work.
Checking Your Driving Habits
Shorter trips daily will negatively affect the lifespan of your battery. Every time you start your vehicle, it reduces the lifespan of that battery. It requires a tremendous amount of power to start your car. The power has to be replenished each time by your vehicles charging system. The shorter trips mean that the battery does not get to charge fully.
Does Revving The Engine Charge The Battery
The battery is charged when the engine is revved, and this is true. As a matter of fact, revving the engine provides the alternator with an additional charge of energy.
The alternator increases the current flow when the engine is revved or the accelerator pedal is pressed. In laymans words, the alternator spins faster, resulting in a quicker charge for your battery than would be possible with an idle motor.
Keeping the engine revved nonstop wastes fuel since it consumes more when it is always being cranked. A few of pauses on the pedal should be enough to get the job done. However, it isnt advisable to keep doing it for an extended period of time..

How Long Does It Take To Charge A Car Battery Using A 12
The answer to the above question depends on the number of amps you are using for battery charging.
For instance:
- 40-Amp Charger: 40 amps has a fast-charging capacity and can charge a car’s battery within a few minutes to an hour.
- 2-Amp Charger: A battery charger with low amp charging, such as 2 amps, can recharge a battery in one to two days. This is because a 2-amp battery provides only 1 ampere per hour.
- 4-Amp Charger: Generally, a car battery holds 48 amps, so using this amount of voltage will take up to twelve hours to reach full battery capacity.
- 10-Amp Charger: A 10-amp charger can recharge a half-discharged small car battery within 2-3 hours and a medium-size car battery within 3-4 hours. A large car battery at 50% charge capacity takes 4-7 hours to reach full charge.
Remove The Jumper Cables After Several Minutes
After several minutes, you can remove the jumper cables in the following order:

Locate the vehicle battery – usually situated in the engine bay under the bonnet, but in some vehicles, it is located in the boot. Itll probably be hidden under a plastic cover unclip this and you should see the battery with its two terminals.
Connect the positive lead from the battery pack to the positive terminal of the battery. Connect the negative lead to a good earth point on the casualty vehicle a solid metal part of the engine is usually best.
Stand the battery pack on the ground next to the vehicle, the leads are usually long enough to reach the battery. Avoid placing it on the engine as it might fall off when the engine starts.
Once the battery pack is connected, switch on the pack and attempt to start the vehicle as you normally would. If it doesnt start after a few attempts, it might be more serious than a flat battery. In this event, seek professional help by .
If the vehicle does start, keep the engine running for about 5 minutes. Switch off the engine, then switch off the battery pack and remove the leads from the battery pack. Now restart the engine again.
The vehicles battery will need to recharge fully for it to be fully serviceable, which is best achieved using a quality battery charger for several hours. In the meantime, if possible, drive the vehicle normally for around 30 mins to try to put some charge back into the battery.
Inspect And Clean Your Jumper Cables
Make sure the connectors and wires are in good shape and rust free. Clean the clamps before attaching them to the car batteries. Even unused clamps may have gunk if theyve been sitting in your garage or the trunk of your car for an extended period of time.
If you have a portable jump starter, it likely comes with cables. These are the ones youll want to inspect.

Must You Drive After Getting A Jump Start Or Is Idling Enough
After a jumpstart, you have the option of driving or letting the engine idle for a period of time. In order for the alternator to charge the battery for the next start-up, the engine must be running.
There is no difference whether you are driving or simply idling the engine. You can drive it or leave it for at least 30 minutes as long as the engine is running.
As a result of this, the battery may be charged more quickly while driving than if the engine was left to idle.
Let it idle for a time, and youll save a lot of gas while also recharging your automobile. On the other handIdling your car is a convenient option if youre at home and dont plan on going anywhere else.
As a result, if youre already on your way, you can go on. In order to ensure that the battery has enough juice, you should only let the engine run if youll be there in under 30 minutes.
How Long Should The Jump Starter Battery Last
How long does the jump starter battery last? Many people that Ive met through the years have attested to a jump starter battery lasting for more than four years, Ive used mine for longer than that. Ive used my jumper battery for more than six years without any glitches. But maybe Ive kept mine in perfect conditions than most and for accurate predictions well need to go through the manufacturers declarations before jumping into any conclusions.
Many vehicle enthusiasts have many varying opinions on the real lifespan of a battery. For most, an average jump starter battery should last more than six years, while others claim it to last for more than that. However, for those working in the car manufacturing industry, claim these to be under normal conditions.
Normal conditions mean the right amount of temperature, humidity, and some types of chemicals in the atmosphere. For instance, an environment with high acidity levels is likely to reduce the lifespan of a battery. Other factors that contribute to a longer lifespan include the correct and recommended full charge cycles and the right amount of power passed. Unfortunately for many motorists, the idea of normal conditions has the proper electronic items in the vehicle, driving under adverse conditions and much worse.
Under the worst conditions, the best you can hope for your battery to last is three years and at best four years. Youd even be lucky to have your jumper battery last for those three years.

When To Test Your Jump Starter
You should test your jump starter regularly. One of the things that happen is that a driver forgets to check their jump starter, leaving it in their vehicle for months or even years, and then, when their battery actually does go dead and they need to use their jump starter it doesnt have enough of a charge to start their vehicle.
You should check your jump starter regularly when you dont need it to start your car and make sure that is it capable of giving juice to your battery once a month is a good benchmark to use, although you can probably go every six weeks and still be safe as well.
How To Clean A Car Battery

Disconnecting The Jumper Cables
If your car does start, leave it running. Now disconnect the battery cables by first removing the negative clamp from the bare metal connection under your car’s hood. Then remove the red clamp from your battery’s positive terminaland do not let the clamps touch. Place them on the ground with the clamps separated. Then remove the red clamp from the good battery, and finally, remove the black clamp. You’ve jump-started your vehicle and are good to gofor now, anyway.
Connect The Jumper Cables
Once the running vehicle is maneuvered into position, shut it off and open both hoods.
When handling jumper cables, make sure to keep the red and black clamps from touching each other. Once electricity starts flowing through the cables, this will create sparks and could lead to a short circuit in one or both of the vehicles. Having one person at each end of the cables can make the whole process easier.
The clamps connect to battery terminals, which are exposed metal nodes with wires connected to them. Before connecting the cables, make sure to brush away any dirt or grime to ensure a good connection. Confirm which terminal is positive and which one is negative . Youll normally find each symbol on the battery itself, next to the terminal. Sometimes the positive is under a red cover. Ask for help when in doubt it will save you a potentially costly repair bill.
Found them? Good. Connect one of the red clamps to the positive terminal of the dead battery. Then, connect the other red clamp to the positive terminal of the live battery. Next, connect a black clamp to the negative terminal of the live battery. Instead of connecting the second black to the negative terminal on the dead battery, find an unpainted metal surface on the vehicle and connect it to that instead. This will make jumping safer.

Avoiding Voltage Spikes When Jump
When you connect jumper cables from a running vehicle to a dead battery, the alternator in the running vehicle instantly puts out maximum charging voltage. That can create a voltage spike of up to 15.5 volts in both vehicles. And its that voltage spike that can fry computers and digital devices.
One way to eliminate the voltage spike is to leave the engine off in the donor car. That will prevent frying computers in the donor car. But if the car wont start right up, dont grind away to the point that you end up with dead batteries in both cars!
Jump-starting with a jumper pack is a better alternative. The battery inside the jumper pack provides the boost to the dead battery at a safe voltage. When used properly, its the safest way to protect the electronics in the dead vehicle while providing enough boost to get the engine running.
