## Can I use a battery with lower ah?

CAN I SUBSTITUTE A LOWER AMP HOUR (AH) BATTERY WITH A HIGHER ONE? As long as the battery that you are substituting is the same voltage, **you can use a higher capacity (higher Ah) battery than the original one**. … You must also keep in mind that the charge time for a higher Ah battery will be longer than a lower Ah battery.

## How many amps should a new car battery have?

An average car battery has a capacity of around **48 amp hours** which means that, fully charged, it delivers 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on.

## What is the difference between a 2.0 Ah battery and a 4.0 Ah battery?

A 2.0Ah battery pack will have five 3.6V cells – each with 2.0Ah capacity – connected in series, and a 4.0Ah pack will have **two sets of five batteries connected in parallel**.

## Should I charge my car battery at 2 amps or 10 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. The short answer: 10 amp chargers are generally preferable than 2 amp chargers.

## 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.

## How many amps should a 12v car battery have?

Car batteries will typically have a capacity of **48 amp hours**. What this means is a fully-charged 12-volt car battery rated at 48 amp hours can deliver 1 amp for 48 hours or 2 amps for 24 hours.

## How many amps should a car battery draw when off?

Most vehicles draw some battery current when the key is off, thanks to the clock and the internal memory of engine computers, body-control modules, and radio presets. Altogether, they draw a very small amount of current. **Fifty milliamps** would be a safe upper limit for this, though many vehicles will draw less.

## Will a higher amp battery damage my car?

As several people have stated, no, **a larger battery will not harm your alternator** (or other electrical components), provided that it is putting out the correct voltage.

## Can I put a higher rated battery in my car?

As **long as the battery will physically fit in the battery box**, the cables connect and the hold down hardware can be made to fit you will be fine. Larger batteries have more reserve capacity.

## What is the difference between 4Ah and 5Ah battery?

These two batteries have the same dimension and have the same voltage. The only difference is confirmed by the small weight disparity in the power of the amp-hour. … If you are using a 4Ah battery and heading towards the 5Ah would mean that **your application could run up to 25% longer**.

## Is higher or lower amps better?

**Higher voltage is better** when current has to travel long distances. A low amp and high voltage system allows you to reduce the amount of electrical current, so less of it is lost as it travels through wires, while still delivering the same amount of horsepower at the end.

## What does the amp hour rating on a battery mean?

Amp hour is **the rating used to tell consumers how much amperage a battery can provide for exactly one hour**. … This means that is supplies 26.8 amps in the duration of 5 hours without dropping off. Meanwhile, the same battery may safely provide 36 amp hours for a period of 100 hours.
