Two headsets from the same family, and the battery sits in a different place on each — plus one cover that breaks if you open it with a screwdriver. Here's how to replace the battery on a Savi 8210 or 8220 without damaging anything.
Key takeaways
- Savi 8210: battery is on the padded side, not the speaker side.
- Savi 8220: battery is in the earcup opposite the boom arm — not the boom side, despite that being where the controls and charging contacts are.
- On the 8220, open the cover by hand only. A screwdriver will break it, and it won't seat properly afterwards.
- The replacement battery includes the removal tool for the gate screws.
- 8210 and 8220 batteries are different shapes and do not fit each other, despite the headsets sharing most components.
When to replace the battery
A battery that no longer holds a full shift's charge, or a headset that powers down mid-call, is the signal. Rechargeable headset batteries degrade gradually over a few years of daily charging rather than failing outright, so the symptom is usually shrinking runtime rather than a dead headset.
Our wireless headset battery and charging guide covers the wider picture — how long batteries last, what shortens them, and when a replacement is the right call rather than a new headset.

On the 8210, the battery is on the side with only padding — not the speaker side. Worth confirming before you start prising anything.
- Remove the padding. It comes off with light pressure — it's designed to be removable, so it shouldn't need force.
- Remove the two screws on the cover, using the removal tool supplied with your replacement battery.
- Take the old battery out and unplug it from the headset.
- Fit the new battery: plug it in first, then seat it inside the headset, replace the gate and its screws, and press the padding back into place.

On the 8220, the battery is in the earcup opposite the boom arm. This catches people out, because the boom side carries the call controls and is the designated charging side — so it looks like the business end. It isn't where the battery lives.
Myth
The battery cover is stuck, so I'll use a screwdriver to lever it open.Reality
Don't. The 8220's battery cover turns counter-clockwise by hand only. It's a common mistake to reach for a tool, and it breaks the cover — after which it won't sit properly on the headset again. If it feels tight, keep turning with your fingers rather than levering. The supplied tool is for the small gate screws underneath, not the cover.- Turn the battery cover counter-clockwise using your fingers only.
- Remove the small screws from the battery gate, using the tool supplied with your replacement battery.
- Remove the battery and unplug it from the connector.
- Fit the new battery: plug it in first, then seat it inside the headset, replace the gate and screws, and put the cover back on.
Order the right battery
The 8210 and 8220 share most of their components, but not their batteries — the two are different shapes and won't fit each other. Check which model you have before ordering, since they're easy to confuse by sight.
If you're unsure which you own, the boom arm is the quickest tell: on the 8210 the battery is under the padded side, on the 8220 it's under the earcup opposite the boom. Our guide to identifying a Plantronics wireless headset by its base code confirms the model if you need certainty before ordering.
A note on the Savi 8200 series
The Savi 8210 and 8220 have been succeeded by the Savi 8410 and 8420. Replacement batteries for the 8200 series remain the sensible fix while the headsets are otherwise working — a battery costs a fraction of a new system, and the swap takes a few minutes.
If the headset has other problems beyond battery life, or you're replacing several across a team, it's worth weighing the current 8400 series instead. Call us and we'll tell you honestly which makes more sense for your situation.
Where is the battery on a Savi 8210?
On the padded side of the headset, not the speaker side. Remove the padding with light pressure, then unscrew the two screws on the cover using the tool supplied with the replacement battery.
Where is the battery on a Savi 8220?
In the earcup opposite the boom arm. This confuses people because the boom side has the call controls and charging contacts, but the battery is on the other side.
Can I use a screwdriver to open the Savi 8220 battery cover?
No. The cover turns counter-clockwise by hand only — using a tool is a common mistake that breaks it, after which it won't fit properly again. The supplied tool is for the small gate screws underneath, not the cover itself.
Is the Savi 8210 battery the same as the 8220 battery?
No. Despite the headsets sharing most components, the batteries are different shapes and don't fit each other. Confirm your exact model before ordering.
When should I replace my Savi headset battery?
When runtime drops noticeably or the headset powers down mid-call. Rechargeable batteries degrade gradually over a few years of daily charging rather than failing outright, so shrinking talk time is the usual signal.
Both swaps take a few minutes with the tool that ships with the battery. The two things to get right: confirm which model you have before ordering, and never put a tool near the 8220's cover. Call our team at 877-999-3838 if you're unsure which battery you need.
