Temperature Display Water Bottles and Mugs: How the Lid Works, Battery Life and Waterproofing
A temperature display lid shows how hot a drink is before the first sip. For a brand, the questions are practical: how the display turns on, how long the battery lasts, how accurate it is, and whether the lid survives washing. Here are the answers for BG Drinkware’s display lid.
By Feng, Head of After-Sales Service & Online Marketing Lead
A temperature display water bottle has a lid with a small built-in display that shows the drink’s temperature when you touch it. On BG Drinkware’s display lid, a touch turns the display on; the reading is accurate to about ±2°C across a 0–99°C range, and the battery lasts for about 50,000 touches, after which the lid is replaced. The battery is sealed inside the lid and cannot be removed, which keeps the lid reliably waterproof, and it meets CE requirements. The lid can go in a dishwasher and can be fully submerged for washing. BG Drinkware, a drinkware manufacturer in Yongkang, China, offers the display lid as an option on a 650 ml stainless steel coffee mug with a side handle, a ribbed body and a flip-cover sip lid. The minimum order is 500 pieces per colour.
How does a temperature display lid work?
You touch the lid and the display lights up with the drink’s temperature, then switches off again. Because it only lights on a touch, the battery is not running a screen all day. On BG Drinkware’s 650 ml mug, the display lid is an optional configuration; the standard version has a flip-cover lid without a display.

How long does the battery last, and what happens when it runs out?
About 50,000 touches. Used ten times a day, that is well over ten years of checks; used more often, it is still several years. When the battery is finished, the lid is replaced rather than recharged or opened, because the battery is sealed inside to keep water out.
Say this on the product page and the care card, so end customers know the display has a life and the mug does not. If you sell replacement lids, plan them into the order. For other lids on the same kind of mug, see stainless steel coffee mugs with lids.
Is a temperature display lid waterproof?
Yes, on BG Drinkware’s lid. The battery is sealed inside and cannot be removed, so there is no battery door for water to get through. That is why the lid can go in a dishwasher and be fully submerged for washing.
Still run the cleaning you plan to recommend on the finished sample, including any printed logo on the lid or body, before you write the care card. Is stainless steel dishwasher safe? covers the body and finishes.
How accurate is the temperature reading?
About ±2°C across 0–99°C. That is precise enough to tell whether coffee is too hot to drink or has gone cold, which is what the display is for. Present it as a drinking guide on your listing, not as a measuring instrument for uses that need exact temperatures.
The display tells the user the temperature; the double-wall body is what holds it. For how insulated drinkware keeps drinks hot, see how long a thermos keeps coffee hot.
How do you order temperature display mugs in bulk?
Ask for the display-lid version by name when you request the quote and sample, because it is an option, not the default. Send the body colour, logo artwork and quantity per colour. The minimum is 500 pieces per colour; a sample of an existing model takes up to 7 days and bulk 7–12 days after approval.
The mug ships in a colour box of 12 × 9.5 × 21.3 cm, 50 per carton, in 62 × 49.5 × 44 cm cartons at 18 kg gross. Tell your forwarder that the lids contain a battery, and confirm the documents they need. For logo options, see customisation and personalised coffee mugs.
