1800mah battery life how many hours

There are just too many questions you will wonder when designing your device with a battery inside it. The boss just want a cheap and small battery with it, but with no further information on how long does the end customer wants, how small can it be.

Generally, battery life is calculated based on the current rating in milli Ampere per Hour and it is abbreviated as mAh. Ampere is an electrical unit used to measure the current flow towards the load. The battery life or capacity can be calculated from the input current rating of the battery and the load current of the circuit. Battery life will be high when the load current is less and vice versa. The calculation to find out the capacity of battery can be mathematically derived from the below formula When it comes to online calculation, this battery life calculator can assist you to determine the time that how long the battery charge will last. For example, a circuit connected with mAh current rating and it is connected to the load of 40 mAh.

Tell me a bit more about rechargeable batteries, how are they different from primary or throwaway batteries? Why should I buy NiMH rechargeable batteries? What are the primary advantages of NiMH batteries over Alkaline or other rechargeable batteries? How environmentally friendly are NiMH rechargeable batteries? How long can a rechargeable battery last over its life? The advantage of rechargeable batteries is that they can be recharged and reused up to a thousand times and generally they greatly outperform standard everyday throwaway leading brand batteries. The fact that rechargeable batteries can be used again and again represents a massive saving over their useful life. Rechargeable NiMH batteries are also very popular simply due to the fact that they are extremely environmentally friendly. Once charged, these rechargeable batteries can be used in the same way as you would with your previously throwaway batteries of the same size. Better performance in driving electronics and huge money saving are the two major reasons to buy NiMH Nickel metal Hydride rechargeable batteries. They can be charged up to times and last longer than alkaline or NiCd batteries. One set of relatively inexpensive NiMH rechargeable batteries can save you from buying thousands if throwaway alkaline batteries. The mAh capacity rating refers to the storage capacity available for a particular battery. A battery with a capacity rating of mAh could deliver a current of mA for one hour.

Some customers asks for 12v battery run time calculator. USD

.

And how does it affect chargers? The higher the mAh rating of a battery, the more energy it can store, and the longer it can power a device before it needs to be recharged. For example, a battery that can deliver milliamperes of current for 10 hours would have a capacity of 1, mAh. For example, if you have a 5V charger and a 3. This means that the charger will have to output more current to charge the battery to its full capacity. The higher the capacity of the battery, the longer it takes to charge. Similarly, the higher the output current of the charger, the faster the battery charges. No, a charger with a higher mAh rating cannot damage your device.

In our article discussing Ah ampere-hours and Wh watt-hours , we got a ton of questions about the longevity of batteries. To help everybody trying to calculate how long will a battery last, we have created a Battery Life Calculator. Example: If we go camping and depend on batteries for all our power needs, and we have no other means of generating electricity. We use this equation for battery drain time:.

The battery life or capacity can be calculated from the input current rating of the battery and the load current of the circuit. Home Engineering Electrical mAh Battery Life Calculator is an online tool used in electrical engineering to precisely calculate battery life. How to Calculate Battery Capacity? Batteries are available in different current rating due to its high requirement of different industrial and domestic purposes. Here we come some key importace take aways. Impotant note: above are max capacity as there is BMS and wiring cables included for a battery pack. Higher mAh ratings for the same battery type will generally mean longer run times. The advantage of rechargeable batteries is that they can be recharged and reused up to a thousand times and generally they greatly outperform standard everyday throwaway leading brand batteries. Then the battery will last for 20 hours. Stable performance due to flat discharge curve. By continuing with ncalculators. What are the primary advantages of NiMH batteries over Alkaline or other rechargeable batteries?

Generally, battery life is calculated based on the current rating in milli Ampere per Hour and it is abbreviated as mAh.
