Is the battery of SJ-OX1C portable oxygen concentrator rechargeable?

A portable oxygen concentrator battery can typically run from about 1 hour to several hours per charge, depending on the device, flow setting, battery capacity, and battery condition. Continuous flow models usually consume more power than pulse dose units, so battery runtime may be shorter at higher flow settings. The HIDGEEM SJ-OX1C portable oxygen concentrator uses a rechargeable 5200mAh replaceable battery that provides more than 100 minutes of runtime under typical use.

Battery life can vary based on flow rate, temperature, battery age, charging habits, and overall usage conditions. Understanding these factors can help users estimate daily runtime, plan charging time, and decide whether spare batteries are needed for travel, outdoor use, or extended periods away from a power source.

What Affects Battery Runtime?

Battery runtime is mainly affected by battery capacity, battery age, charging condition, temperature, and usage habits. A larger-capacity battery can generally provide longer operating time, while older batteries may gradually lose capacity after repeated charge cycles.

Temperature also matters. Extreme heat or cold can reduce battery efficiency and shorten runtime. Frequent deep discharging, long-term storage at very low charge levels, or using an unsuitable charger may also affect battery performance over time.

To help maintain battery life, keep the battery charged before use, store it in a cool and dry place, avoid extreme temperatures, and use the charger recommended by the manufacturer.

There are 2 ways to charge the battery:

1.      Just connect the battery with the battery charging cable (the charging cable must be connected to the AC adapter) to charge the battery.

2.      Put the battery in the machine, connect the machine to the AC adapter without turning on the machine, the battery will be charged automatically.

You can choose the way you like to charge the battery of SJ-OX1C oxygen concentrator.
