How do I ship Etsy orders that include CR2025 coin cell batteries in a remote?

Hi! A CR2025 is a lithium metal “button/coin cell” battery, and when it’s installed in the remote (with that pull tab) it’s generally OK to mail with USPS as “battery contained in equipment.” For a typical Etsy order with one installed coin cell, you usually don’t need a special lithium battery label when it’s a button cell installed in the device—the key is packaging it so the remote can’t get crushed or accidentally activate in transit.

For USPS (domestic) here’s the safe way to do it:

Packaging steps (do these every time)

• Leave the battery installed (don’t ship loose coin cells unless you really have to).
• Prevent activation: keep the pull tab in place (great), and pack the remote so buttons can’t be pressed (wrap/bubble wrap helps).
• Protect from damage: cushion the remote and lamp so nothing moves around; use a rigid outer box (or a sturdy mailer plus good internal protection).
• No “spares” rattling around: if you include an extra coin cell, treat that as a different (more restricted) situation (see below).

Labels / markings

• For a button cell installed in equipment, USPS rules generally do not require the DOT lithium battery mark on the outside of the package.
• If you add extra loose/spare batteries, the labeling and “ground only” rules can change quickly—so avoid including spares unless you’re prepared to follow the stricter requirements.

Limits per package (the part most sellers worry about)

• For domestic mailing of lithium metal batteries installed in equipment, USPS has quantity limits (and they also say you can’t include more batteries than needed to operate the device). With one CR2025 installed in one remote, you’re well within limits.

USPS Ground service

• Using USPS Ground Advantage is a good choice for battery-containing items. The important thing is that the battery is contained in the remote and the package is packed to prevent damage/activation.

Two quick “watch-outs” for Etsy sellers:

1. International / APO/FPO: lithium rules are often tighter and country-dependent. If you ship internationally, double-check before offering it (many sellers choose to keep battery-included items domestic-only to avoid surprises).
2. Don’t ship damaged/defective/recalled battery devices. That’s where USPS draws hard lines.

If you tell me whether you ship domestic only or also international/APO, and whether you ever include a spare CR2025, I can tell you the exact safest setup for your shipping profile and packing flow.
