At a glance

What is a CR1025 battery?

CR1025 is a 3.0V Li-MnO₂ button cell rated 30mAh (0.090Wh). 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.

Country of OriginChina

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 CR1025 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 CR1025 and ships with its own EU declaration of conformity.

Ordering

What do buyers ask before ordering the CR1025?

How long does a CR1025 battery last?
CR1025 is rated 30mAh / 0.090Wh and runs for 680hours under our published test — test conditions: 62kΩ 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 CR1025 battery?
The CR1025 is built from Lithium, Manganese, Graphite — a Li-MnO₂ system at 3.0V, rated 30mAh / 0.090Wh, about 0.6g (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 CR1025 be stored?
Our storage statement for the CR1025 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 CR1025 rechargeable?
No — the CR1025 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 CR1025 order?
Each CR1025 consignment carries its own EU declaration of conformity (reference TQ-EUDOC-CR1025-20260622) and an MSDS. As a lithium cell, the shipment also carries UN38.3 transport documentation.
How do I order the CR1025 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 CR1025 wholesale pricing?

Factory-direct with OEM custom label & packaging. Samples available.
