Batteries **with** larger **mAh** ratings generally last longer than those **with** smaller ratings, assuming that the batteries are subjected to the same patterns of usage, but it may not mean a **better** battery. The milliampere hour represents a unit of electrical charge commonly used to measure battery capacity.

Hereof, Does higher mAh mean more power?

**mAh** means milliamp Hour and is a unit that measures (electric) **power** over time. It is commonly used to measure the **energy** capacity of a battery. In general, the **more mAh** and the longer the battery capacity or battery life. A **higher** number means that the battery can store **more energy**, so it has a **higher** capacity.

How do you check your battery percentage? Use a **calculator** to divide the figure you wrote down from the meter by the figure from the **battery** label; then multiply the answer by 100 to get the **percentage** capacity in your **battery**.

**Is it better to have more or less mAh?**

Batteries **with** larger **mAh** ratings generally last longer than those **with** smaller ratings, assuming that the batteries are subjected to the same patterns of usage, but it may not mean a **better** battery. The milliampere hour represents a unit of electrical charge commonly used to measure battery capacity.

**How long does a 5000 mAh battery last?**

With moderate use a **5000 mAh battery** is expected to **last** typically a day and a half!

**Is it OK to use a higher mAh battery?**

Q: **Can I use a higher** rated **mAh battery** in my electronic device (i.e. 1800mAh vs. 2000mAh)? A: Yes, the **mAh** rating will give you longer run times between recharges. The **higher** rated **mAh** of a **battery** has no effect on electronic devices other than they allow longer term **use**.

**How do you calculate battery charge time?**

**Here is the formula of charging time of a lead acid battery.**

- Charging time of battery = Battery Ah / Charging Current.
- T = Ah / A.
- Charging current for 120Ah Battery = 120 Ah x (10/100) = 12 Amperes.
- Charging time for 120Ah battery = 120 / 13 = 9.23 Hrs.
- Then 120 x (40 / 100) = 48 …..(120Ah x 40% of losses)

**How do you calculate battery drain?**

If the applied Current is 10 Amperes, then it would be 100Ah/10A= 10 hrs approximately. It is an usual **calculation**. Discharging: Example: **Battery** AH X **Battery** Volt / Applied load. Say, 100 AH X 12V/ 100 Watts = 12 hrs (with 40% loss at the max = 12 x 40 /100 = 4.8 hrs) For sure, the backup will lasts up to 4.8 hrs.
