Shipping Lithium Batteries In The UK With Royal Mail
Sending lithium batteries through the post has become a regulated and careful process. In the UK, Royal Mail permits some shipments containing lithium batteries, but with strict conditions. This guide outlines what you can and cannot send, how to package it properly, and how to stay compliant.
What You Can Send
Royal Mail allows certain lithium batteries when shipped contained within a device, such as:
Mobile phones
Laptops
Cameras
GPS devices
The key is that the battery must not be loose or shipped separately.
What You Cannot Send
Lithium batteries on their own
More than two batteries or four cells per package
Damaged, recalled, or faulty batteries
Any package over 5kg net battery weight
Battery Capacity Limits
Royal Mail follows UN testing guidelines. Ensure your battery falls within the permitted range:
| Battery Type | Max Cell Rating | Max Battery Rating |
|---|---|---|
| Lithium-ion | 20 watt-hours (Wh) | 100 watt-hours (Wh) |
| Lithium metal | 1g lithium per cell | 2g lithium per battery |
Devices must have passed UN Manual of Tests and Criteria, Part III, Section 38.3.
Packaging Requirements
Packaging must prevent movement, accidental activation, or short-circuiting.
Use original retail packaging if possible
Place the device in a plastic bag or strong container
Surround with adequate cushioning
Secure all loose parts
Note: If you're sending multiple devices in one parcel, each must be individually wrapped.
Labelling Requirements
Every parcel must have the correct lithium battery handling label.
Label must include:
A symbol of a battery with flame
The words “Lithium ion batteries in compliance with Section II of PI966”
A contact telephone number
Minimum size: 120mm x 110mm
Common Mistakes to Avoid
| Mistake | Why It's a Problem |
|---|---|
| Sending batteries on their own | Royal Mail prohibits standalone lithium batteries. They must be contained within a device. |
| Exceeding cell or battery capacity | Exceeding watt-hour or lithium gram limits violates postal safety rules and may result in confiscation. |
| Missing hazard label | Without proper labeling, your parcel may be rejected or delayed by the postal service. |
| Shipping damaged or recalled batteries | These are banned entirely due to fire risk and safety regulations. |
