The Honest Truth



I love how tough these battery cannisters are but I think the fact that you can make the most of Ammonite’s modular system and use your Accu Battery with any of their torch heads puts them in a class of their own.

Durability and Reliability

The Ammonite Accu Batteries are designed for robustness and reliability. The main section and lower lid of each battery is machined from a solid piece of Delrin®, a highly durable construction thermoplastic. The upper lid, made from hard anodised aluminium, resists abrasion and weather factors while providing increased thread strength for repeated use. Each canister is doubly sealed with O-rings and features an overpressure safety valve.


Easy to Attach

Standard models of the Ammonite Accu Batteries include a webbing fixed loop fastening to the hip belt. Options such as the sidemount buckle or Accu click mount are available for alternative fastening systems.


Part of the Modular System

Ammonite Accu Batteries are part of a modular system, allowing you to tailor your umbilical light set to your diving needs. With a consistent chinch type connector across all components, upgrading or replacing parts is straightforward and convenient.


Small Size, Low Weight

Among the market’s smallest and lightest, Ammonite Accu Batteries provide power without the bulk.


Universal and Safe Power Supply

The batteries offer a safe and universal power source for all Ammonite System umbilical lights, ensuring bright light and extended burn times. Each battery pack, contains a Li-Ion battery that is safeguarded against short-circuit and overvoltage.


Eco-Friendly Packages
