Frequently Asked About CR2477 LiMnO2 Button Cell Battery

How long will my order take, how can I pay, and what are the shipping options?

Lead Time: Standard samples typically arrive in 7-12 days. Formal orders usually take around 25 days, though smaller quantities might ship faster, potentially within 15-18 days.
Payment Methods: We accept various payment types, including T/T (Telegraphic Transfer), L/C (Letter of Credit), and PayPal.
Shipping: We offer flexibility! Depending on your needs and location, we can ship your order via air freight (using carriers like FEDEX, DHL, UPS, EMS, etc.) or via sea freight.
Delivery Terms: We can work with several common international shipping terms, including EXW, FCA, FOB, CFR, and DDU.

What is your minimum order quantity (MOQ), and can I get samples first?

We have a minimum order value of USD $500. The actual quantity you receive depends on the unit price of the specific batteries you choose. Absolutely! We understand you need to test our products. We're happy to provide samples for your evaluation before you place a formal order.

What technical information do you need from me to determine the best battery for my product?

We must understand your product's specific usage scenario to recommend the most suitable battery, including the required dimensions, operating temperature range, and the typical/maximum operating current.

Can these coin cell batteries be customized for product integration?

Yes, we support the customization of CR cell batteries for product integration. This includes adding solder tabs and pins according to your specific requirements.

Is the CR2477 battery rechargeable?

No, the CR2477 is a primary (non-rechargeable) battery. It is designed for single use only, and attempting to recharge it is extremely dangerous. Recharging can lead to severe safety hazards, including internal short-circuits, leakage, overheating, rupture, or fire. Always replace a depleted CR2477 battery with a new one.

Can I use a CR2450 or CR2032 battery as a replacement for a CR2477?

No, you cannot. This is a common point of confusion, but the CR2477, CR2450, and CR2032 are not interchangeable. While all are 3V lithium coin cells, they have different physical dimensions. The CR2477 has a diameter of 24mm and is 7.7mm thick, while the CR2450 is 24mm x 5.0mm and the CR2032 is 20mm x 3.2mm. The significant difference in thickness means that a thinner battery will not make proper contact in a CR2477 compartment, and a thicker CR2477 will not fit at all in a device designed for a smaller battery.

What essential safety precautions should be followed when handling CR2477 batteries?

While generally safe when used correctly, proper handling is crucial. Because coin cell batteries can pose a choking hazard, they must be kept out of reach of children and pets. Additionally, you should:

Never try to recharge the battery.
Do not short-circuit the terminals.
Avoid puncturing, crushing, or disassembling the cell.
Keep it away from open flames and extreme heat beyond its specified operating temperature.
Dispose of used or damaged batteries properly according to local regulations for lithium batteries.
