At a glance
What is a CR2016 battery?
CR2016 is a 3.0V Li-MnO₂ button cell rated 75mAh ~ 100mAh. 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 CR2016 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 CR2016 and ships with its own EU declaration of conformity.

Documentation
What do buyers ask about the CR2016 data sheet and EU declaration?
Where is the EU declaration of conformity for the CR2016?
Every CR2016 shipment carries its own EU declaration of conformity (document TQ-EUDOC-CR2016-20260622) 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 CR2016 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 CR2016 as a product — interchangeable numbers, packaging formats and bulk supply.
Are the CR2016 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 CR2016?
How long does a CR2016 battery last?
CR2016 is rated 75mAh / 0.225Wh and runs for 700hours under our published test — test conditions: 30kΩ 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 CR2016 battery?
The CR2016 is built from Lithium, Manganese, Graphite — a Li-MnO₂ system at 3.0V, rated 75mAh / 0.225Wh, about 1.6-1.9g (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 CR2016 be stored?
Our storage statement for the CR2016 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 CR2016 rechargeable?
No — the CR2016 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 CR2016 order?
Each CR2016 consignment carries its own EU declaration of conformity (reference TQ-EUDOC-CR2016-20260622) and an MSDS. As a lithium cell, the shipment also carries UN38.3 transport documentation.
How do I order the CR2016 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 CR2016 wholesale pricing?
Factory-direct with OEM custom label & packaging. Samples available.
