Lithium Batteries Fine For Princeton Tec Torches

Recent search suggests that using lithium batteries with some LED headtorches could cause damage and lead to reduced bulb life, but this doesn't, says Princeton Tec, apply to its torches.

The US-based lighting specialist says that it recognised the problem during its own research and took it into account when designing its LED models allowing you to use lithium cells without encountering problems.

The main advantage of lithium technology is lighter weight and longer burn times and, particularly relevant for outdoor use, significantly improved performance in cold weather when conventional alkaline and rechargeable batteries slow down as the chemical reactions inside them are retarded.

The company says power regulating circuits eliminate the problems while giving better and more understandable burn times - there are some issues with the way these are measured generally with LED torches, which can be confusing.

Princeton Tec models using the technology include the £30 Quad (pictured) - a 96-gramme, 4-LED lightweight all-rounder with a 150-hour burn time - Eos and the very bright Apex torches and we've been very impressed with test samples from the company in the past.
