How long should you charge a new car battery?

Do I need to drive car after new battery?
If your car does start, let it run for a few minutes to help charge the battery further. Unhook the clamps in the reverse order of how you put them on. Be sure to drive your car for about 30 minutes before stopping again so the battery can continue to charge. Otherwise, you might need another jump start.
What happens if you disconnect the positive terminal first?
If positive terminal is removed first then chances of a spark are more if this terminal touches the body through the metal spanner or wrench you are opening with is grounded accidentally and may end in flames because lot of combustible material is around. And chances of this accidental touch are very high.
Should I charge my new car battery before installing?
Your new car battery should be fully charged prior to installation, otherwise you risk overloading and/or damaging the charging system. (It’s not designed to recharge a dead battery.)The order in which you disconnect the dead car battery’s cables is key: Always disconnect the negative cable first.
Should I trickle charge a new battery?
A trickle chargers’ primary purpose is to slowly charge a battery and prevent overcharging – however, the same result can be achieved through the use of a standard charger. If storing batteries for a period of time is a common activity, then it’s safe to say a trickle charger may be a good investment.
How do you charge a car battery for the first time?

- Connect black clamp from a charger to the negative terminal of a battery.
- Insert power cable from a charger to the wall power outlet and start the charger.
Does a car battery charge while idling?
Assuming the alternator, engine, belt, and battery are all in working order, then yes, a car battery will charge when idling. The only caveat is that it doesn’t really “charge” that fast. This is solely due to the fact that the engine doesn’t have a load on it when your car is simply idling.
How long does a new car battery last if not used?
If you’re dealing with a fully charged battery that’s relatively new and in perfect condition, it will take 2-3 months for it to lose its power completely. However, you’re probably pushing your luck if you let it sit idle for more than two months.
Do you put red or black on first?
Connect the positive terminal first. Attach the red (positive) terminal to the positive battery post. Tighten the terminal with a wrench. Repeat the process with the black (negative) terminal.
Do I connect positive or negative first?
When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.” When you are replacing your car battery, It isn’t always easy to remember the order in which to disconnect and reconnect the terminals.
Why do you remove the negative terminal first?
If you’re disconnecting the positive terminal first, and the spanner touches any part of body or engine, you’ll get a massive spark and potentially damage your battery also. By disconnecting the negative first, you eliminate the risk of *grounding” your battery on the car body or engine.
What happens if you connect the negative terminal first?
It is only a safety issue. If you first connect the negative cable, then when you connect the positive cable there is a chance the wrench will complete a circuit between the battery and the chassis of the car. This will at a minimum generate a spark, but that spark could eject molten metal toward you causing injury.
Does a new battery improve car performance?
Higher fuel consumption:
A tortured alternator has other side effects too. It forces the car engine to enforce more power than it generally does. Such kind of extra enforcing leads to excessive higher fuel consumption, even in shorter journeys. It all leads to the reduction of the car’s fuel efficiency in the long run.
What should you do prior to charging the batteries?
If your battery does have cell caps, they must be removed before you begin charging, otherwise gases created by charging will not be able to escape into the atmosphere. Make sure that the car is turned off and then attach the cables or the wires to the battery terminals. The charger will have two wires.
How long does it take to charge a car battery with a 12 volt charger?

What is the difference between a battery maintainer and a trickle charger?
Trickle chargers are meant to be disconnected when they’re done charging, while battery maintainers can be left plugged in. Remember, since all battery maintainers are “smart,” they won’t deliver any charge to a battery that’s already full.
Can you overcharge a car battery?
Yes, overcharging a car battery is possible. The vast majority of car batteries on the market are lead-acid, which can stand a certain amount of overcharging. The real problem is if the overcharging is continuous, even at low levels. This will eventually boil the battery dry and damage the internal lead plates.
How often should I drive my car to keep the battery charged?
Keep the battery charged by driving your car once per week
For instance, a garaged, new car — with a brand-new battery, presumably — will fare better than an older car parked on the street. Keep in mind that batteries tend to drain faster in colder climates.
How far do you need to drive to charge a car battery?
“It needs to be driven and not idled.” That means driving at least 10 km at a time, and longer in the winter, because you’re using the heater, rear defroster and heated seats – they draw a lot of power, which means less power will be available to recharge the battery, Feist says.
