At a glance
What is a CR2032 battery?
CR2032 is a 3.0V Li-MnO₂ button cell rated 190mAh ~ 255mAh. Lithium manganese dioxide cells hold a steady 3.0 V for most of their life, which is why they are the default choice for memory backup, key fobs, remote controls and low-current sensors. TIANQIU manufactures and supplies it factory-direct, with OEM label and packaging.

Lithium manganese dioxide cells hold a steady 3.0 V for most of their life, which is why they are the default choice for memory backup, key fobs, remote controls and low-current sensors. The CR2032 is produced on our own lines in China and can be supplied as a bare cell, on a blister card or in a printed box. Each is marked for CR2032 and ships with its own EU declaration of conformity.

Documentation
What do buyers ask about the CR2032 data sheet and EU declaration?
Where is the EU declaration of conformity for the CR2032?
Every CR2032 shipment carries its own EU declaration of conformity (document TQ-EUDOC-CR2032-20260418) and an MSDS, plus UN38.3 transport documentation for the lithium cell. Ask for the current file set and we send the signed copies.
How is this page different from the CR2032 model page?
This page is the technical record: capacity, the performance table with its discharge conditions, materials and the compliance file. The model page covers the CR2032 as a product — interchangeable numbers, packaging formats and bulk supply.
Are the CR2032 performance figures measured or nominal?
The performance table is the measured data we hold for the model at the discharge conditions printed with it. Nominal figures are labelled nominal, and typical capacity is given as a range because it moves with the cut-off voltage.
Ordering
What do buyers ask before ordering the CR2032?
How long does a CR2032 battery last?
CR2032 is rated 190mAh / 0.57Wh and runs for 950hours under our published test — test conditions: 15kΩ continuously to 2.0V @ 20±2℃. Service life in your device depends on the load and the cut-off voltage, so send us the device and we will size the cell for it.
What is inside a CR2032 battery?
The CR2032 is built from Lithium, Manganese, Graphite — a Li-MnO₂ system at 3.0V, rated 190mAh / 0.57Wh, about 2.9-3.1g (only for reference). The material list belongs to this model's technical file, and the MSDS for the chemistry comes with the documentation set.
How long can a CR2032 be stored?
Our storage statement for the CR2032 reads: One year after delivery under normal storage, 98% of initial capacity maintained. Keep the cells in the original packaging; the storage and transport guidance that applies to this 3.0V Li-MnO₂ model goes out with the shipment paperwork.
Is the CR2032 rechargeable?
No — the CR2032 is a primary (non-rechargeable) cell. Charging a primary cell can cause leakage or rupture, so replace it rather than recharge it. If your application needs recharging, ask us for the rechargeable range.
Which documents come with a CR2032 order?
Each CR2032 consignment carries its own EU declaration of conformity (reference TQ-EUDOC-CR2032-20260418) and an MSDS. As a lithium cell, the shipment also carries UN38.3 transport documentation.
How do I order the CR2032 in bulk?
Send the model, your annual quantity and the packaging format. First orders start from 50 cartons per product line, and printing on the cell, blister card and box is done in our own plant with your logo and barcode.
How do I get CR2032 wholesale pricing?
Factory-direct with OEM custom label & packaging. Samples available.
