ResMed S9 -- 295WH *SUPER* Battery

• MAINTENANCE FREE: - NO ATTENTION NEEDED, EVER!
• BEST INVESTMENT: Compared to the good old reliable Sealed Lead Acid (SLA) battery we've sold for years which have a maximum of 300 discharge / recharge DUTY CYCLES before it was worn out, the new LiFePO4 batteries have between 4000 to 5000 Duty Cycles of life expectancy. You will likely be using this battery to power your next 3 PAP Devices (you'll only need to update the PAP DC Power Cord each model change. You can buy that cord from us at a "Returning Customer Discount".)
• Female "Cigarette Lighter" Socket is compatible with most DC Power Cords for most brands of PAP Devices.
• USB PORTS - (2) Fused USB-2 Ports on the Voltmeter allow you to recharge your cell phone, GPS, or tablet, even during a blackout!
• VOLTMETER - Easily check to see how much power is left.
• COMPACT - Battery is 7 inches long x 3 inches wide x 8 inches tall.
• PORTABLE & LIGHTWEIGHT - Battery weighs 8 Lbs. This battery is about 1/3 the weight of a lead-acid battery of the same capacity.

• EASILY RECHARGED - Battery can be recharged off any "house current", or a generator, or while driving down the road (with additional accessory.) Also can be recharged with optional Solar Panel.

It prevents overheating, overcharging, reversed polarity, catching fire, or harming any medical devices hooked up to it. Furthermore, the battery is totally sealed and spill-proof, you can even use it resting upside-down!
• 295WH rates as 79,730 mAH at 3.7V  will power most PAP Devices for 5-8 Nights* 
• 10 YEAR WARRANTY (Prorated) - Battery is warrantied against defect for 10 Years with full-replacement for the first 24 months. (All other accessories like Battery Charger or DC Power Cords have a 5 YEAR Warranty (Prorated).
• CHARGER - We provide you with a 3AMP Battery Charger that is SILENT. It will charge your 295WH battery to a full charge in a little over 7 hours. NOTE: This Battery charger is specifically designed to charge this LiFePO4 battery to a fuller level than a typical Lead Acid charger can reach.
• O.E.M. DC POWER CORD  -  ALL the DC Power Cords / Converters that we sell with this special battery system are "Original Equipment Manufactured" "O.E.M." cords made by the Cpap Manufacturers for their specific PAP Devices.  NO AFTER MARKET "WANNABEES".  They are all fuse-protected and static filtered to eliminate electronic emissions that could otherwise interfere with nearby electronics like cell phones, gaming consoles, or wifi signals. We extend the Factory Warranty to 5 years because we know these are the best cords available anywhere for PAP equipment.

*NOTE: All performance claims are based on user turning all comfort heaters (Ie. Humidifier Heat and Heated Tubing) to OFF or ZERO since these features consume up to SIX times as much battery power as running the device without them turned on. A "night" of sleep is considered 7 hrs based on USA average for adults.
