All about Batteries...

The torches we stock here at Extreme Torches use a range of different battery chemistries. These include:

Alkaline

The 1.5v alkaline-manganese dioxide battery was introduced in the early 1960's and remains very common place in today's battery market.

These can be used in our AA compatible torches, however due to how the voltage in an Alkaline battery 'sags' under a high load, don't expect great runtime (especially at higher brightness / current levels).

NiMH
Nickel-metal hydride batteries are the rechargeable cells most people know of. Available in AAA, AA, C and D sizes, they can be used nearly everywhere a alkaline can. Although their voltage is lower 1.2v vs 1.5v for Alkaline, they are much better suited to high drain devices and experience less voltage sag.

NiMH batteries used to suffer from self discharge, where a NiMH battery once charged would eventually become dead even with little or no use.

With the recent release of the Sanyo Eneloop range of batteries, self discharge is now a thing of the past. Eneloop batteries once charged can be relied on to retain 85% of their capacity after one year.

These are the pick of the crop for AA battery torches.

Li-ION

Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery's life. In addition, the self-discharge is very low. With a nominal voltage of 3.6v, these pack a lot of punch in a small form factor.

At Extreme Torches many of our torches can utilise these batteries, with some only running on Li-ION.

We stock these cells in the following sizes:

•    16340 / R123A (Same size as disposable CR123 but 3.6v)                - 750 mAH capacity
•    14500 (AA size)                                                                                          - 750 maH capacity
•    17670                                                                                                            - 1600 mAH capacity
•    18650                                                                                                            - 2200 mAH capacity
•    

Extreme Torches stock a range of Li-ION batteries, please contact us for information...


Li-ION Chargers
We currently do not stock any Li-ION battery chargers. These are quite easily available from websites like Ebay etc.
We are currently working on sourcing some high quality Li-ION chargers. Please contact us to see whether these are available.

Li-ION Safety

Please be aware that Li-ION batteries can be dangerous if mistreated or misused. The batteries and chargers listed on our website are for use only by qualified individuals. Please ensure that you have sufficient knowledge in handling these products before purchasing.

• Never charge or use Li-ION or any other battery type unattended
• Only charge the batteries in a fire proof container or surface
• Make sure you are using the correct charger for the right battery
• Make sure that if you are using a Li-ION charger, that it is on the correct setting for the battery being charged

Please contact us if you have any queries or questions.

Thanks - Extreme Torches
