## Top best answers to the question Â«How many amps should i charge my car battery atÂ»

A basic charger usually charges at around 2 amps - and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market - from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.

### đź‘‰ How many cranking amps should battery have?

• On the current market, you'll find most car batteries running on a total capacity of 550 to 1000 amperes (cranking amps), depending on the chemistry going around its inner components, such as lead-acid, absorbent glass mat (AGM), or sealed lead-acid batteries (SLA). 3. How many amps does my car battery take to start the engine?

### đź‘‰ Should i charge my car battery at 2 amps or 6 amps?

Consequently, when trying to charge a larger battery at that rate, it will take a very long time and the battery may discharge at a greater rate than the 2-amp charge can provide. It is better to charge a deep cycle battery at a higher charge rate like 6-amps, 10-amps or higher.

### đź‘‰ How many amps does an alternator charge a battery at?

For a battery being charged by the car's alternator it can take an hour of driving to get it fully charged. Car batteries range from 40AH to 110AH, and alternators range from 45 amps to 200 amps.

How many amps should you charge your car battery at? Charging a car battery at 4 to 7.5 amps is the safest and most efficient. Charging amps in this range will allow the battery to be completely charged overnight and will not be at risk of overcharging.

As for car batteries, it is a rule of thumb not to fast charge them using anything that exceeds 20 amps. Slow charging using 10 amp chargers or less is generally accepted to be better. This is because repeatedly fast-charging a car battery may lead to overcharging and will severely reduce its performance.

How many Amps to Charge a Car Battery. If your car battery is 12-volts, it will begin the charging process at 13.8 volts which is the pressure behind the amps. The amount of amps used is up to the owner but common amp chargers are 1.5 or 2 to top off or maintain, or 4-6 amps to charge a battery from dead overnight.

The basic car battery is a 48 amp battery so it would take a 24 hour period of charging at 2 amps for the battery to receive a complete charge.

Going down this route, a car battery takes 24 hours to be fully charged at 48 amperes. There are other variants of battery chargers as well, one with a 10-amp-per-hour rate, but theyâ€™re not recommended for battery life unless you need to finish the charging process in a hurry.

How many amps to charge a car battery Most battery chargers send about 2 amps of power to your battery per hour. At this rate, it typically takes over 24 hours to fully charge the battery. The advantage of this relatively low charging rate is that youâ€™re less likely to overcharge the battery, which can reduce its overall lifespan.

A car battery usually holds 48 amps so if you take that it charges at approximately 1 amp per hour you can work out how long it will take to charge your battery with various amperage chargers. Charging your battery with a four amp charger will take about 12 hours to get a full charge out of this low amperage.

Considering you have a healthy battery and the battery is completely discharged: For round numbers takes a 150 amp deep cycle battery. Charge it at 10 amps, you will need to charge that battery for...

Aside from jump starting (the fastest, but not always the most efficient method), you can also consider using a reliable car battery charger. There are many chargers available on the market, from small systems designed to be light and affordable to highly advanced, automatic battery chargers. These modern chargers not only offer efficiency, but they will also switch to a low-amp maintenance mode once the battery has a full charge. JUMP START YOUR CAR â€“ THE QUICK SOLUTION
