1800mah battery life how many hours

There are just too many questions you will wonder when designing your device with a battery inside it.

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.

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.

The battery life or capacity can be calculated from the input current rating of the battery and the load current of the circuit. The fact that rechargeable batteries can be used again and again represents a massive saving over their useful life. You must login to use this feature!

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:. What does ah mean on a battery? It just means amp-hours. Example: How long will a Ah amp-hour battery last if we hook it up to a 1 Ah electric device? Basically, a Ah battery means that such a battery can provide A of current for 1 hour. It can also provide 1 A current for hours.

GPS Battery Pack. The mAh capacity rating refers to the storage capacity available for a particular battery. That means you could still be using the same batteries you buy today in 10 years time! Thickness mm. Impotant note: above are max capacity as there is BMS and wiring cables included for a battery pack. The fact that rechargeable batteries can be used again and again represents a massive saving over their useful life. PS: quick notes: if space allows, cylindrical battery cells will always be your first consideration on the table. Calculate for me. By continuing with ncalculators. How long can a rechargeable battery last over its life? Some customers asks for 12v battery run time calculator ,. So how to calculate how long a battery will last? The actual capacity will be very complex, but luckily we have a simple and fast calculate formula. Once charged, these rechargeable batteries can be used in the same way as you would with your previously throwaway batteries of the same size. Capacity Rating.

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.

Why should I buy NiMH rechargeable batteries? A battery with a capacity rating of mAh could deliver a current of mA for one hour. We here have 2 ways for you to get the battery capaicty. GPS Battery Pack. The actual capacity will be very complex, but luckily we have a simple and fast calculate formula. Here we come some key importace take aways. Thickness mm. Actully the formula works for all volts including 12V rechargeable battery. Rechargeable NiMH batteries are also very popular simply due to the fact that they are extremely environmentally friendly. Generally, battery life is calculated based on the current rating in milli Ampere per Hour and it is abbreviated as mAh.
