At a glance
What is a CR2477 battery?
CR2477 is a 3.0V Li-MnO₂ button cell rated 1000mAh. 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 CR2477 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 CR2477 and ships with its own EU declaration of conformity.

Ordering
What do buyers ask before ordering the CR2477?
How long does a CR2477 battery last?
CR2477 is rated 1000mAh / 3.00Wh and runs for 1480hours under our published test — test conditions: 4.7kΩ 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 CR2477 battery?
The CR2477 is built from Lithium, Manganese, Natural graphite — a Li-MnO₂ system at 3.0V, rated 1000mAh / 3.00Wh, about 8.5g (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 CR2477 be stored?
Our storage statement for the CR2477 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 CR2477 rechargeable?
No — the CR2477 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 CR2477 order?
Each CR2477 consignment carries its own EU declaration of conformity (reference TQ-EUDOC-CR2477-20260701) and an MSDS. As a lithium cell, the shipment also carries UN38.3 transport documentation.
How do I order the CR2477 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 CR2477 wholesale pricing?
Factory-direct with OEM custom label & packaging. Samples available.
