What Battery? Battery Rating and Capacity Explained

Deciding what battery rating or model your product requires is simply a matter of following the manufacturers instructions.

However, it can be useful to understand a few simple terms when purchasing new or replacement batteries. This will help you purchase the most efficient and powerful battery for the job. This can be especially important when dealing with emergency equipment or lighting, where some extra capacity may just save

Here we will explain the specification of batteries you may encounter in the Travel Mono Store.

Battery Voltage

Voltage (V) in a battery is a measurement of the batteries electric potential. The Higher the voltage the greater the electrical potential.

When purchasing a battery we are given the nominal voltage measurement as a reference. The nominal voltage is measured at the mid-point between full charged and fully discharged. A single lithium battery cell nominal voltage is usually shown as either 3.6V, 3.7V or 3.8V.  

What is mAH?

A battery is also rated using a unit of measurement called a milliampere hour (mAH). This unit of measurement is 1000th of an ampere hour (Ah).

The ampere hour is a unit of battery energy capacity. This measurement is equal to the total continuous current multiplied by the discharge time before all chemical energy has been discharged.

Calculating battery method this way is not accurate and it is advised to use a voltage tester for testing battery life.

Battery Size and Shape

Most people will be familiar with the common cylindrical batteries used in everyday household items.

These models can include A, AA, AAA, AAAA, B, C, D and various sizes in between.
