What is the battery life of a lithium-ion battery?
The minimum lifespan most manufacturers expect from lithium-ion batteries is around 5 years or at least 2,000 charging cycles. But, if well cared for and used in proper conditions, lithium-ion batteries can last as long as 3,000 cycles.
What does mAh mean on a battery?
The capacity of batteries is indicated as XXXX mAh (milliampere/hour). The formula for calculation is as follows: Capacity (milliampere/hour) = discharge (milliampere) x discharging time (hour) E.g. Take a Ni-MH rechargeable battery with a capacity of 2000 milliampere/hour.
How long does a 8000mah battery last?
At a rate of 8,000 mAmps (or by the way, 8 Amps) the battery would drain in one hour. If drawing half the current or 4,000 mAmps the battery would last 2 hours.
How long will 800mAh battery last?

How long will my batteries last?
To determine how long your battery will last, calculate the battery’s total capacity and divide it by your circuit’s power. Multiply the battery’s reserve capacity by 60. With a reserve capacity, for instance, of 120: 120 x 60 = 7,200.
What 2000mAh means?
mAh is the capacity rating of the battery. Small batteries like this one are rated in milli-amperes or thousandths of an ampere. A 2000mAh rating means that the battery can supply 2000mA (or 2 amps) of current for the time period of the rating. A higher number means a battery with a higher capacity, and vice-versa.
Should I charge my phone now?
When should I charge my phone? The golden rule is to keep your battery topped up somewhere between 30% and 90% most of the time. Top it up when it drops below 50%, but unplug it before it hits 100%. For this reason, you might want to reconsider leaving it plugged in overnight.
