In mid 2017 a decision has been made to gradually discontinue production of all iconic NLG5xx models for good. Last order date for the NLG5 was set to November 15th 2017. The rationale behind this decision according to BRUSA is that ~16 years old design and technology is not suitable for mass production, and also some parts for it are no longer available from sub-suppliers (some of whom are out of business by now).
However, no official announcements regarding this fate of the NLG5xx have been made by BRUSA on their official website so far. This information, while not privileged or proprietary, was circulated only internally to distributors worldwide.
The fate of newly developed BRUSA NLG66x battery chargers is currently being decided. Due to changes in company management, original intent to ramp down and terminate mass production of all the hardware during 2018 (including the NLG6) is being reconsidered and direction the company will take was not formally announced. The NLG6 were discontinued in its current form, however it is expected that the company might re-design these chargers to be better suitable for high volume production in future. No formal announcements on this were made yet. This applies to the NLG664 and the NLG667 charger models.
Please stay tuned for further updates.
