MyoLift Mini & 600 Portable Battery: Charging and Runtime FAQ

Straight answers on the MyoLift Mini and 600 portable battery: how charging works, what affects runtime, when to replace it, and why a serial number is requested.
Quick answer
Charge your MyoLift Mini or 600 portable battery fully before a session, top it up after each use, and replace it when it no longer holds a charge through your normal routine. The replacement battery is a 3.7 V lithium-ion pack, and orders for it require your device serial number before they ship.
Why the serial number check exists
The MyoLift Mini and MyoLift 600 use different device generations, and the battery listing covers both. Once your order is received, the 7E Wellness team emails you to request the serial number on your device, and the order stays on hold until you provide it. That step protects you from receiving a pack that does not match your unit. Have the device nearby when you order so you can read the serial number without delay.
What shortens runtime in real use
Battery life between charges depends on how long each session runs, how often you treat, and how bright or intense your device settings are. A daily 10-minute routine drains the pack far more slowly than long, frequent sessions. If your routine changes, expect the interval between charges to change too. The catalog does not publish a specific hour rating for this pack, so judge runtime by your own sessions rather than a fixed number.
When replacement is the right call
A pack that still charges but drains within one session, or that shuts the device off mid-treatment, is a sign the cell has aged. Before ordering, rule out a loose connection at the lead wire or a probe that needs reseating. If the device powers on only while plugged in, the battery is the likely culprit. Replacement is a maintenance step, not a device upgrade.
MyoLift battery questions, answered
- How do I charge the MyoLift portable battery?
- Use the charging method specified for your MyoLift Mini or 600 model and charge fully before a session. The catalog does not list a charge time or charger specification for this pack, so follow the device manual rather than guessing. Check your device manual for the exact charger and charge time before your first use.
- How long does the battery last per charge?
- There is no published hour rating. Runtime depends on session length, treatment frequency, and device settings. Track how many sessions you complete between charges to set a realistic expectation.
- Should I charge after every session?
- Top up after each use if you treat daily, and avoid storing the pack fully drained for long periods. A full charge before a session prevents mid-treatment shutdowns.
- How do I know the battery needs replacing?
- Replace it when the device only runs while plugged in, shuts off mid-session, or drains within a single routine despite a full charge. First check the lead wire and probe connections.
- Why is a serial number required for the replacement battery?
- The listing serves both the MyoLift Mini and MyoLift 600. 7E Wellness emails you for the device serial number after your order is received and holds the order until you provide it, so the correct pack is sent. Locate your serial number before ordering to avoid a shipping hold.
- Can I use the same battery in both the Mini and the 600?
- The catalog lists one replacement battery for both the MyoLift Mini and MyoLift 600. The serial number check confirms compatibility with your specific unit.
