Maximize Portability with the Ultimate Lightweight Fit

Breathe easier and stay light on your feet with the Inogen One G4 4-Cell Single Battery. This is the original battery designed for those who want their concentrator to remain as small and unnoticeable as possible. Whether you prefer to wear your device on your shoulder or clipped to your belt, the single battery ensures zero strain during movement, making it the most discreet power solution for your daily respiratory care.

The World’s Lightest Therapy Path

The 4-cell single battery is specifically engineered to minimize bulk. Because it adds only a few hundred grams to your device, it significantly reduces shoulder and hip fatigue. This makes it an excellent choice for patients with limited physical strength who need to remain active for short periods without being weighed down by heavy equipment.

2.7 Hours of Cordless Range

Providing up to 2.7 hours of oxygen at Setting 1, the single battery provides enough range to get you to your next charger comfortably. It is the perfect choice for users who spend most of their time near a power source but need total mobility for the drive between destinations, medical visits, or brief outdoor strolls.

Official OEM Protection

As a genuine Inogen part, this battery is designed to maintain your device's 24/7 reliability. It features advanced safety logic that communicates directly with your G4 machine to regulate temperature and power draw, preventing overheating and ensuring the longest possible lifespan for your expensive medical concentrator.

Features

Optimized Power Delivery

Utilizes high-quality lithium cells with a steady discharge rate, ensuring your oxygen output remains precise and constant from the first minute to the last second of charge.

Rapid Charge Times

Because of its compact size, the 4-cell single battery can be fully recharged in roughly 3 hours, ensuring you spend more time active and less time waiting by the charger.

High-Resolution Molding

The casing is made from medical-grade, high-impact polycarbonate. This durable material acts as a rugged shield for the internal power cells during daily movement and outdoor activities.

Advanced Safety Monitoring

Built-in thermal fuses prevent the lithium-ion cells from overheating during rapid charging or high-temp storage, protecting your health and the integrity of your equipment.

Easy-Touch Release Latch

Designed for maximum ease of use, the tactile release button requires minimal pressure, allowing users with arthritis or limited finger mobility to swap power sources effortlessly.

Accurate Power Tracking

Internal sensors work in harmony with the G4 display to provide a real-time countdown of remaining therapy minutes, allowing you to move through your day without the anxiety of a sudden shutdown.
