Whether you’re a seasoned hiker, just looking for a reliable source of light for your evening jog, or in have a serious head torch for hunting and fishing, having the right battery is essential for getting the most out of your head torch.

Rechargeable head torch batteries have come a long way since lithium ion batteries started to appear in more and more everyday devices so lets get stuck into it.

Finding the right head torch batteries.

First and foremost, we need to establish if you need a button top type or a flat top type. Button tops have a positive terminal that looks like a regular battery with a small raised bump or button on the top. Flat tops are as the name suggests, have a flat positive terminal.


Then it’s important to consider the capacity of the battery. The capacity is measured in milliamp hours (mAh) and refers to the amount of energy the battery can store. Generally speaking, the higher the capacity, the longer the battery will last. However, higher capacity batteries also tend to be heavier and more expensive, so it’s important to find the right balance between capacity, weight, and cost.


Discharge output is another interesting factor, it’s important to remember that in great scheme of things your head torch doesn’t require a huge output, when compared to say a vape. Between 10A and 8A will be plenty for the average head lamp, but ensure to check with the manufacturers guidelines as well, some specific units may be able to draw more to give you a brighter light, but this comes at the expense of operational time between charges.


Another important factor to consider is the voltage of the battery. Most head torches are designed to be used with batteries that have a voltage of 3.7V, but it’s important to check the specifications of your particular head torch before making a purchase. Using a battery with the wrong voltage can cause damage to your head torch or even pose a safety risk.


Ultimately, the right Li-ion battery for your head torch will depend on your specific needs and preferences. By considering factors like capacity, output, voltage, and battery type, you can find a battery that will provide the power and reliability you need to get the most out of your head torch. With the right battery, you can explore the outdoors with confidence and never be left in the dark.
