## How long will a 1500 mAh battery last?

If the load is 500mA, the cell’s usable capacity actually drops to approximately 1500 mAh, and 1500/500 is only 3 hours. Devices like remote controls do not use continuous power.

## What does 1500 mAh battery mean?

For example, a battery rated at 1500 mAh can power a device drawing 100 milliamps for 15 hours, or a device drawing 150 milliamps for 10 hours. (In other words, a device using more power will drain the same battery faster.)

How many mAh is an hour?

1000 mAh is equal to a 1 Amp Hour (AH) rating.

### How do you calculate hours from mAh?

An Amp-hour, also denoted as an Ampere-hour, is a measure of charge and equates to current flow over time. One Amp-hour is equal to one amp of continuous current flow for one hour. A milliamp-hour, or milliampere-hour, is one thousandth of an amp-hour, therefore a 1000 mAh battery would be equal to a 1 Ah battery.

### How long does a 1000mah battery last?

You should be able to power a circuit of 1,000 mA for an hour with the 1,000 mAH on your battery. Divide your load power by this. The load should last for 2 hours if it’s 500 mA and 30 minutes if it’s 2,000 mA.

How long does it take to charge a 1400 mAh battery?

RE: How long to charge a 1400mah NiMH? It’s going to take at least 24 hrs to deliver 1400 mah with the charger.

## How long does 1000mah battery last?

How long does 1100mAh battery last?

Normally an 1100mAh battery will last me at least 10 hours. These batteries however last me just 3-4 hours. That puts these batteries in the range of 400 to 650mAh.

### How long does a 1200mAh battery take to charge?

built-in 1200mAh rechargeable lithium battery, provides 3-4 hours of play time, and fully charged in 2 hours through the supplied Micro-USB cable. You can enjoy music all day or all night, alone or in a party. Connect to the phone up to 33 feet (10 meters) away. 1.

How many hours does a 1800 mAh battery last?

one hour
The mAh capacity rating refers to the storage capacity available for a particular battery. A battery with a capacity rating of 1800 mAh could deliver a current of 1800mA for one hour.

## What is 1000mAh battery?

If you have a battery and you don’t know what it’s capacity it is, all you have to do is hook it up to supply a 1000 mA discharge and see how long it lasts. If it lasts an hour, hey, you’ve got a 1000mAh battery. If it lasts 7 and a half hours, well then you’re holding a 7500mAh battery.

## How many hours does a 1000mah battery last?

How long does it take to charge a 1500mAh battery?

The only way to really find out is to time it, and the simple calculation dividing the mAh capacity by the mA supply, 1500/500 = 3 hours, is a pretty good rule of thumb and a far more pragmatic way of estimating the time. How do I take time to fully charge a 2000mAh battery?

### How do I know if my battery is 1500mAh or 1000mAh?

If it lasts an hour, hey, you’ve got a 1000mAh battery. If it lasts 1 and a half hours, well then you’re holding a 1500mAh battery. Always remember that battery discharge rate depends on current drawn by the load so one cannot the estimate the discharge time of battery without knowing the load which is connected to battery. Hope it’s useful..

### How long does a 3000 mAh battery last?

For example, if you have a 3000 mAh battery that runs at 5 Volts and 15 Watts, then the time that the battery will last for is (3000*5)/ (15*1000) = 1 Hours.

How do you calculate the Mah of a battery?

With larger batteries, like car batteries, we usually use ampere hours, or Ah. There are 1000 mAh in a single Ah. mAh is calculated by multiplying the amount of time the battery lasts by the amperes of the discharge current.
