Battery Features:

12.8V 20Ah Lithium Iron Phosphate (LiFePO4) Portable Rechargeable Battery



High Capacity: This battery capacity is 256 Watt-hour( 12.8V 20Ah)

Light Weight: This battery only weighs 5.6 pounds. A same capacity lead acid battery may weigh 13 pounds

This battery has two Input/Output connectors. You may use them to charge battery or get power from battery. One end is 5.5 x 2.5mm female connector with positive polarity ( Inside positive, outside negative/ground). Another end has two wires with Anderson Power Pole connector. Red Wire is positive, Black wire is negative/ground.

Lithium Iron Phosphate (LiFePO4)Pros:

Long life span (5-10 years) vs lead acid (1-3 years), depending on depth of discharge and assuming that the cycle limit doesn't kill the battery first Longer cycle life, as LiFePO4 batteries last 1,000 to 3,000 charge and discharge cycles, compared to similarly sized lead-acid batteries, which can range from 200 - 1000 cycles (again, assuming depth of discharge is within recommended limits for both battery types).

Very safe - the odds of a "thermal runaway" (aka battery fire) are very low. The same can not be said of other lithium ion chemistry.

Charge the battery:

This battery can be charged from any 100V ~ 240V, 50Hz/60Hz AC power source with the battery AC charger. It only takes around 3 hours to fully charge the battery



You may use the battery while charging battery. This will make battery to services like a UPS (Uninterrupted Power Supply): The AC charger will charge battery and at same time provide power to CPAP while it has power. When AC charger has not power, the battery will provide power to CPAP Machine.
