FAQs

  • Amp hours indicate how long a battery can power a device before it needs to be recharged. The higher the amp-hour rating of a battery, the longer it will last before it needs to be recharged.

    As a rough estimate, a battery with a rating of 5Ah can deliver 5 amps of current for about one hour, or 1 amp of current for about 5 hours, before it needs to be recharged. Similarly, a battery with a rating of 10Ah can deliver 10 amps of current for about one hour, or 1 amp of current for about 10 hours, before it needs to be recharged.

    They are an important consideration when choosing a battery, as they determine how long the device can operate before the battery needs to be recharged.

  • Higher amp-hours in a battery do not necessarily mean that it is better for every application. The right battery depends on the specific needs of the application.

    A battery with higher amp-hours has a larger capacity and can deliver power for a longer duration before it needs to be recharged. 

    However, a battery with higher amp-hours is usually larger and heavier than a battery with lower amp-hours. This can make it less suitable for portable devices that require lightweight and compact batteries, such as handheld power tools or smartphones.

  • Low-Power Applications: Batteries with amp-hour ratings of 1-2Ah are suitable for low-power applications, and are ideal for cordless drills, drivers, radios and flashlights. These batteries are lightweight and compact, making them ideal for portable devices.

    Medium-Power Applications: Batteries with amp-hour ratings of 3-4Ah are suitable for medium-power applications, such as string trimmers, reciprocating saws, circular saws, and other power tools. These batteries offer a balance between power and run time and are suitable for tasks that require moderate power consumption.

    High-Power Applications: Batteries with amp-hour ratings of 5-6Ah or higher are suitable for high-power applications, such as heavy-duty power tools such as chainsaws, lawn mowers and saws.
