Our NEW Lithium-Polymer (Li-Po) CPAP Battery range heralds a new level of quality and features.

These superbly crafted batteries packs are powerful enough for all your CPAP needs, but small enough and light enough to be carried on your belt in the neoprene case provided.

The concept is so simple. The battery packs have the most straightforward interface. An input socket to charge the battery from the mains, or the car, a special output socket to power the CPAP, a fuel gauge, and a fuel gauge push button.

The supplied mains and car chargers have coloured LEDs to indicate charging and fully charged. A cigar lighter socket output lead is provided with each battery.

Additional output leads are also available from stock. For example rather than use the cigar lighter socket lead, use a special bullet to 2.1mm DC plug lead to connect the battery directly to an EcoStar or a special bullet to DC 2.5mm plug lead for a DreamStar CPAP.

We can ship worldwide.

The most popular size is the C120. Up to two of these 120Wh battery can be taken on an aircraft in hand luggage.

This new 120 Watt hour (Wh) battery provides your CPAP with 12 volts direct current (12V DC). It is suitable for use on an aircraft and can even be used to charge up your mobile phone, tablet computer (ipad or similar) or digital camera using a cigar lighter to USB adaptor (not supplied). The battery can be recharged from the mains 110V or 240V AC, (it takes between 9 - 14 hours to charge from flat with the supplied charger or 4 - 7 hours with the optional fast mains charger). It can be topped up from your car or boat\'s 12V cigar lighter socket. It has a push button operated fuel gauge. A single push causes up to 5 LEDs to show depending upon the level of charge remaining.

The C120 Lithium-Polymer CPAP battery is safe when treated and used correctly. It has a robust ABS casing & soft grip texture. Its Integrated Electronic \'Battery Management System\' (BMS) provides the following protection:

  • Overcharge & over-discharge protection
  • Thermal protection
  • Over current protection
  • Short circuit protection

It is CE marked and conforms to UN 38.3, a requirement for air travel. This battery has been through a rigorous testing procedure by UN certified inspectors.

To double the runtime, two identical batteries can be coupled together using our special pigtail adaptor. This is a safe way to maximised the capacity of the batteries but the current must never be more than 3A, and the batteries must not be charged at the same time as being used to power a device, i.e., used as an uninterruptible power supply.

Size 80mm x 152mm x 48mm. Weight 735g.

The C120 kit comprises the following:

  • Mains charger with indicator LED and pins for UK, USA, Europe and Australia. Li-ion battery charger output 12.6V DC 1.65A with 1.05m long lead and 2.1mm DC plug to fit the CHARGE DC12V socket on the battery. The charger\'s LED shines Red when charging and Green when fully charged.

  • Neoprene belt-looped carry case.

  • Car charger with indicator LED. Car charger output 12.0V 1.00A with 1.5m long lead with cigar lighter plug to fit socket in car or boat and 2.1mm DC plug other end to fit CHARGE DC12V socket on battery for charging when on the move. The charger\'s LED shines Red when charging and Green when fully charged.

  • Cigar lighter socket lead - Cigar lighter socket with lead and special bullet plug to fit NOMINAL 12V OUTPUT on battery.

  • Manufacturer\'s instruction and Safety Precautions books including warranty information.

  • Our CPAP Battery Pack user instructions.

We can supply all additional converters and inverters for every type of CPAP machine. Please call us to order.

The battery is not suitable for use with CPAP with humidifiers set to on, or to heat water in a kettle, ski boot heaters or similar high wattage items. The maximum continuous discharge current of the battery is stated as 10A. However, the Cigar lighter socket lead is rated at 8A maximum, the optional cigar lighter plug to 2.1mm DC power cable is rated at 5A maximum, the optional Special bullet to DC 2.1mm plug and Special bullet to DC 2.5mm plug leads are rated at 2A maximum. Although a ResMed S8 shows 2.5A on its rating plate, in tests we have found that even at a pressure of 20mbar it draws just under 2A including the converter.

The lithium battery has become my favourite travelling companion! Lightweight, easy to use and gives me two nights' uninterrupted sleep. Originally gave three nights but dropped to the two night mark on 4th use - hope this doesn't decrease further... Charging is quite slow and needs fairly constant monitoring as overcharging decreases performance. Excellent customer service on purchase.
