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.

Impotant note: above are max capacity as there is BMS and wiring cables included for a battery pack. Stable performance due to flat discharge curve.

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.

We have grown accustomed to relying on these gadgets for a variety of functions, from smartphones and tablets to laptops and portable power stations. Making sure that our devices have adequate battery life to last the entire day is one of our toughest difficulties, though. Here is where the idea of mAh comes into play. In this blog, we will delve into the details of mAh, explaining what it is, how it works, and why it matters for consumers. We will cover the basics of electricity and battery technology, and explain how mAh is used to measure the amount of energy a battery can store. By the end of this blog, you will have a better understanding of mAh and its role in battery life, allowing you to make more informed decisions when choosing electronic devices. Before we can dive into mAh and battery capacity, we need to understand the basics of electricity and battery technology.

For a mAh 2. There are just too many questions you will wonder when designing your device with a battery inside it. This means that you may not be able to predict how long your electronic device will run just by looking at the capacity rating of a battery. Friendly to the Environment — no toxic chemical Back to top Q4. For a 36V Li-ion Battery with capacity of 24Ah battery delivering 2A current, then you can constantly use your battery for:. Or you can use 3. Ebike Lithium Battery. Back to top Q2. 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. Ampere is an electrical unit used to measure the current flow towards the load. Forgot your password? Close Download. You cannot convert watts to amps, HOWEVER, if you have at least two of the following three: amps, volts or watts then the missing one can be calculated. Batteries are available in different current rating due to its high requirement of different industrial and domestic purposes.

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.

If the capacity is given in amp-hours and current in amps, time will be in hours charging or discharging. Chances are that once you get into rechargeable batteries you will never use a throwaway again. Design For Me. Feel Confused? How environmentally friendly are NiMH rechargeable batteries? Friendly to the Environment — no toxic chemical Back to top Q4. 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. You must login to use this feature! PS: quick notes: if space allows, cylindrical battery cells will always be your first consideration on the table. The lithium battery usually comes with a pouch or cylindrical form. Privacy Terms Disclaimer Feedback. Energy Density of Different Battery Types. Back to top Q5.
