Crowcon’s LIBRA (Lithium ion Battery Replacement Assembly) battery is available for use with all existing and new-build Triple Plus+ (TRP+) and Triple Plus +IR (TRP+IR) gas detectors.

The battery is said to makes the detectors even more versatile and dependable, with extended lifetime and charge cycles.

LIBRA contains a microprocessor and circuitry to mimic the previous lead-acid battery pack, which means that users can replace their battery with a LIBRA without needing to perform any modifications on their TRP+/TRP+IR or change the charger.

LIBRA also provides power for 20-30min after low-battery warning, allowing users to complete their task and replace the battery.

The development offers users a solution that is compliant to their existing operating procedures; for example, there is no impact on the requirement to see the minimum operating voltage of 6.3V.

Crowcon has also introduced a more forceful low-battery alarm indication based on customer feedback, which is available as standard in all new builds (after November 2009) and also in the form of a service-replaceable Eprom upgrade.

Lithium-ion batteries are claimed to be lighter and provide more energy than lead-acid equivalent batteries.

They also hold their charge, even on the shelf, and can be more effectively controlled by electronics.

In addition, they have no ‘memory effect’ and so can be recharged at any time without losing any overall life or cycle time.

LIBRA guarantees a full two years of charge cycles without any reduction in run time and offers a minimum three years of reliable use, assuming extreme recharging patterns.
