For example, for a phone with 2000 mAh capacity and 0.8 battery health, a power bank with 10000 mAh capacity and 0.8 conversion can give a charge for about 3.2 times (10000 x 0.8 x 0.8 / 2000 ...
How Long Does Dewalt Battery Take To Charge? (Explained!)
It''s not unusual for it to take up to two hours before a 60V/6.0Ah Dewalt battery is fully charged—assuming the use of a 36V/28V fast charger, that is. With more inferior types or slower models of chargers, though, you can probably expect longer periods until they achieve peak efficiency levels again!

Why does the battery capacity decay?
A fully charged Li-ion battery stored at 40°C (104°F) for one year without use can cause a 35% capacity loss. Ultra-fast charging and discharging is also harmful to the battery, reducing the battery life by half, which is very noticeable regarding single lithium-ion batteries.

Lithium-ion (Li-ion) batteries have become the preferred power source for electric vehicles (EVs) due to their high energy density, low self-discharge rate, and long cycle life.
How can you tell if a battery is fully charged?
The only accurate way to tell if a VRLA DRY CELL AGM or GEL battery is fully charged is by using a good voltmeter to determine the open circuit voltage (OCV) without any load applied to the battery. Accessible flooded-type batteries can also use a hydrometer. Table 5 - State of Charge vs. OCV

Why do lithium-ion batteries degrade over time?
Charge cycles and lifetime. A battery charge cycle refers to the complete drainage and recharge of a battery: draining a battery to 0% and recharging it to 100% is equal to one battery charge cycle. A charge cycle can also be completed by using 50% of the battery, recharging it to 100% and then repeating this procedure.
