Libra Battery For Triple Plus+ Gas Detectors
Crowcon Detection Instruments has announced that the Libra (Lithium-ion battery replacement assembly) battery is now available for use with all Triple Plus+ and Triple Plus+IR gas detectors. The company said this makes the detectors more versatile and dependable, with extended lifetime and charge cycles. Libra contains a microprocessor and circuitry to mimic the previous lead-acid battery pack; this means users can simply replace their lead-acid battery pack with a Libra without needing to modify their Triple Plus+ and Triple Plus+IR gas detectors or change the charger.
Libra also provides power for 20-30 minutes after low-battery warning, allowing users to complete their task and replace the battery. Core to the development was the need to offer existing users a solution compliant to their existing operating procedures. For example, there is no impact on the requirement to see the minimum operating voltage of 6.3V. At the same time, Crowcon has introduced a more forceful low-battery alarm indication. This improvement is available as standard in all new builds (after November 2009) and also in the form of a service-replaceable Eprom upgrade. Lithium-ion (Li-ion) batteries are said to have a number of advantages over competing technologies.
They are generally lighter than lead-acid equivalent batteries, they provide much more energy than lead-acid batteries; they hold their charge (even on the shelf) and can be more effectively controlled by electronics; and they have no 'memory effect' and so can be recharged at any time without losing any overall life or cycle time - this means increased lifetime and charge cycles. Assuming a five-day working week, a 48-week year and a gas detector being charged overnight after every working day, the battery will experience 240 charging cycles per year.
Under these conditions, Libra guarantees a full two years of charge cycles without any reduction in run time. At the end of the following 240 charge cycles, a 25 per cent reduction in run time may be experienced. Libra therefore offers, at the very minimum, three years of reliable use, assuming extreme recharging patterns. This time will be extended if the battery is not used completely or not charged as frequently. Libra Li-ion batteries are also more environmentally friendly than alternatives.
