This specification provides the technical requirements of the CR1212. The battery complies with the international and EU standards listed below; unless otherwise specified, requirements and sizes shall meet or exceed the referenced standard.
-20℃ ~ +60℃
Per IEC 60086-5 for aqueous-electrolyte batteries — confirm with our engineers for your specific device.
These references are electrically compatible. Always match size and voltage before replacing.
CR1212 is used every day in these classes of devices — the cell is matched to each duty below, and every pack is tested against the appliance profile before dispatch.
Car key fobs and remote-entry keychains: the cell sits behind the removable rubber cap. A fresh cell restores the push-to-start response and the range that fade as voltage drops.
BIOS backup cell on desktop and server motherboards. When it fades, the system forgets the clock and BIOS settings after power-off — replacement takes a minute and restores a clean startup.
Buy in Bulk: CR1212 available for distribution in bulk packs, 5-pcs child-resistant cards or custom retail packaging under your brand. From blister cards to display boxes, your private label battery brand on every cell. Minimum order 50 cartons (about US$2,000) — a proven entry for chains testing private label battery lines.
Manufacturer declaration by DongGuan Tianqiu per Regulation (EU) 2023/1542 — compliance documents per model are stored on this site; models without a published declaration are issued per batch on request.
Chemical system (EU declaration): Lithium Manganese Dioxide (Li-MnO₂) · 3V
Primary batteries are non-rechargeable; keep out of reach of children.
Declaration Available on RequestThe official EU declaration for the CR1212 is issued by our compliance team on request — per-batch COA and test data included. Contact us for the current document package.

Swallowing or ingestion of any button cell battery is a life-threatening injury!
Swallowing can lead to chemical burns, perforation of soft tissue, and death. Severe burns can occur within 2 hours of ingestion. Seek medical attention immediately.
If you are looking for a CR1212 replacement, the key is to match the coin cell · 3V · watch · replacement references listed above before ordering — CR1212 batteries ship in 5-pcs/10-pcs cards or bulk packs with full specification documents.
Buyers often compare CR1212 against coin cell · 3V · watch · replacement — they share diameter or voltage but differ in thickness and capacity, so always match the original cell. Our engineers confirm compatibility for your device and provide the matching reference without guesswork.
For distributors and OEM buyers searching CR1212 bulk, price and lead time: we supply from 50 cartons (≈ US$2,000) with volume-laddered pricing, shipping marks and transport certificates — request the current price list for your volumes.
From first inquiry to production line in five steps, with one engineer on your order from start to finish.
Quantity in cartons or pieces, destination port and market. We reply within 24 hours with a complete quotation.
Spec sheets first, then samples by express in 3–7 days so you can test fit and performance on your own device.
Price, MOQ (from 50 cartons, approx. US$2,000) and lead time are fixed in the offer, and the price is held for 30 days.
Your logo, pack design and artwork enter the prepress flow; before mass production we print one sample box for your visual approval.
Mass production runs about 35 days from sample approval, with per-batch COA and transport certificates (UN38.3 for lithium cells) in the shipment.
Real OEM programs from the same factory — the ones that use this cell first, then other lines running at our site.
Remote battery line for TV and AC accessories: LR6/2BP and LR03/2BP paper packs under the customer label, 24 pcs per box, built around two seasonal production windows.
CASE 02Locksmith and car-accessory channel supply: CR2032 on 5-pcs child-resistant cards (EU retail requirement), quarter replenishment driven by store sell-out.
CASE 03Holiday gift-set line: AA/AAA in 2/4/8-pcs shrink packs with cartoon artwork, mixed-SKU cartons dropped to the customer warehouse.
The CR1212 is a Lithium cell of 12.5 mm × 1.2 mm rated 3V. Capacity and packing data are listed in the specification table on our product page.
CR1212 matches reference ECRCR1212 in our battery catalog — always match size and voltage before replacing.
Service life depends on the device drain: typical use is 1–3 years, and shelf life is 3–5 years when stored cool and dry. Bulk figures are confirmed by our engineers.
No — the CR1212 is a primary (non-rechargeable) Lithium battery. Attempting to recharge it may cause leakage, fire or explosion; for rechargeable options see our rechargeable battery page.
CR1212 references ECRCR1212 in different naming systems — IEC, AG and retail labels name the same size cell differently.
