CR2450 Is a button battery, a lithium manganese dioxide battery system. It has a diameter of 24.5 mm and a thickness of 5.0 mm, and is usually used in electronic devices that require higher capacity.
The main parameters of the CR2450
Standard voltage 3V operating temperature range-20~C60° self-discharge rate 2% Maximum pulse current: 5 mA Maximum continuous discharge current: 3 mA Maximum external size: diameter 24.5 mm, height 5.0 mm.The maximum continuous discharge current refers to the maximum current corresponding to the constant discharge of the battery with a constant current of 2.0V to obtain 50% of the nominal capacity.
Battery structure and composition
• Manganese dioxide positive electrode, lithium negative electrode, organic electroliquid, diaphragm and stainless steel shell, etc
• Nominal capacity: 600 mAh (or 3100h) (15 KQ load resistance discharged to 2.0V at 23 + 3℃)
Precautions for use
Inappropriate use of batteries can cause risks. Here are some things to pay attention to when using CR2450.
• Do not heat up or throw the battery into the fire.![[VNA6G]2KVWCLQUF9H_L`6A.png](/image/ueditor/php/upload/image/20250110/1736498866978097.png "1736498866978097.png")
• Do not put the battery into the water or in a wet environment.
• Do not place the batteries in your pocket or bag together with the metals such as necklaces, hairpins, coin clips, or screws, and do not store the batteries together with these items.
• Do not use the positive and negative electrodes of the metal conductor short-circuit battery.pay attention to the positive and negative electrodes of the battery when installing the device.1. Don't break down the battery.
• Do not weld the battery directly.
• Do not use batteries with severe scars or deformation.
• Please read the operation instructions in detail before use. Improper operation may cause battery heating, ignition, explosion, destruction or attenuation of battery capacity.
Applied range
CR2450 Battery is a very wide range of applications, mainly used in some of the more high capacity requirements of electronic equipment, including watches. Calculators, Bluetooth headsets, and other smart wearable devices, remote controls, and toys. Small working equipment.
CR2450 And CR2032 difference
