NJ1020HP for Phillips M3 and M4 monitors

The Inspired Energy NJ1020HP is one of our most popular standard smart batteries and is used worldwide in Phillips M3 and M4 patient monitors (the battery is also known by the part numbers M3046A, 1420-0551 or M3046-61302).  Today I thought I would give you some more information on this fantastic product and tell you more about the power behind it.

First, the power source:

The NJ1020HP contains ten Nickel Metal Hydride 4/3 cells – these provide excellent service life for important applications such as patient monitors. Each cell is rated at 1.2V and 3.8Ah (Ampere Hours). When ten are connected together in series they make a 12V 3.8Ah battery. As battery safety is paramount the battery also contains three passive safety devices to ensure it can never be over charged or over loaded – the NJ1020HP is a VERY safe product.

Second, the electronics:
The NJ1020HP is a ‘smart battery’ – this means that is contains electronic circuitry which constantly monitors the charge and discharge activity of the battery and uses this to accurately report the state of charge to the Phillips monitor. The NJ1020HP also has a four bar LED display which presents the battery capacity in 25% increments when you push the button on the top of the battery.

Third – The case and connector:
The NJ1020HP has a tough, flame retardant plastic casing which ensures no harm comes to either the cells or electronics. The 5-way connector on the end of the battery is a genuine part from Tyco and allows the battery to charge, discharge and communicate with the Philips M3 or M4 monitor.

Need a charger? Many of our customers find that our CH5000 (single bay) and CH5050 (dual bay) desktop charger / calibrators are the perfect companion to the NJ1020HP – these chargers allow the batteries to be charged away from the patient monitor and the calibrating function allows the electronic fuel gauge to be calibrated, bringing it back in line with the performance of the cells. This function would normally be performed by the medical engineering department in a hospital when the monitor goes down for its annual service. I have visited medical engineering departments here in the UK and they find these charger/calibrators invaluable.

If you need more information on our NJ1020HP then you can visit our website. You can purchase up to 23 batteries online or request a quote if you want more, or simply contact Customer Service on 01782 566688 or and we'll be glad to help.

Smarter than the average charger

~ Medical devices increase demand for smart battery and charger solutions ~

Accutronics will showcase its skills in the design, development and manufacturing of medical batteries and smart chargers at COMPAMED 2013, in Dusseldorf. The technology used by the Newcastle-under-Lyme provider of battery solutions allows intelligent communication between the battery and charger. This increases the device’s safety, reduces charge time and maximises battery life. Compamed will take place between November 20 and November 22, Accutronics can be found in Hall 8b Stand F30. 

A smart charger contains a microprocessor designed to communicate with smart batteries that have embedded microchips. Accutronics’ smart batteries and chargers are used worldwide in devices such as ventilators, nebulisers, patient monitors and endoscopy data recorders.

The technology ensures that the battery remains in control, only requesting voltage and current from the charger when it needs it. This ensures that the battery will not be overcharged and saves energy.

Another significant advantage of Accutronics’ smart charger technology is that it is chemistry independent, which means that it doesn’t need to be upgraded as new generation batteries are released. This is particularly important in a field where technology is evolving fast and the incompatibility of different generation products is a common problem.

The company’s smart chargers are flexible in both design and use. They can be developed to accept either low voltage direct current (DC) or alternate current (AC) supply. Furthermore, single or multiple bay solutions are possible, depending on customer requirements.

“Accutronics develops specific custom batteries and chargers for its original equipment manufacturer (OEM) customers through its AccuPro service,” explained Rob Phillips, managing director of Accutronics. “Our aim is to offer tailored solutions for professional high technology markets, such as the medical and healthcare sectors.

“In an ideal situation, Accutronics would work with the customer from the early stages of product development and create a customised solution for each individual project,” continued Phillips. “However, we also have the Entellion product range which provides off the shelf solutions, saving our customers time and cost. Our credit card and VR420 battery range together with our recently released, modular, Intelligent Power Vault® are examples of Entellion in practice.

“The former delivers high power in a compact, credit card sized unit, while the latter incorporates the latest Lithium-ion smart battery technology, intelligent charging circuitry and efficient regulated power control in a high energy, rechargeable battery system that is easily designed into medical devices and power backup equipment.”
