Upgrade your device’s power with this 863450 2000mAh Li-ion battery. This replacement cell serves as a direct and superior substitute for older 853450 and 803450 battery models. It features a built-in protection board with pre-attached wires, providing essential safeguards against overcharging, over-discharging, and short circuits. The 2000mAh capacity offers reliable extended runtime for a wide range of applications. Made with grade A cells. CE, RoHS, and UN38.3 certified for safety compliance.
Designed for DIY and Small Electronics: This 863450 battery is a versatile power solution for hobbyists, makers, and repair enthusiasts. Common applications include small electronics, handheld devices, DIY projects, backup power systems, portable gadgets, and replacements for worn-out batteries in various consumer devices. The pre-attached wires simplify the installation process compared to bare cells — while soldering is still required, the wires eliminate the need to solder directly onto the battery tabs, reducing the risk of heat damage to the cell. The built-in protection board adds an extra layer of safety, automatically preventing overcharge beyond 4.26V, over-discharge below 2.75V, and short circuit conditions. With a cycle life of 500 cycles (retaining 85% capacity), this battery is designed for long-term reliability. Whether you are repairing a handheld gaming console, upgrading a portable speaker, or building a custom power bank, this 863450 battery provides dependable power in a compact 8.6×34×50mm form factor.
Compatibility Note: This is a universal battery that directly replaces 803450 and 853450 models. The 863450 model number indicates the dimensions: approximately 8.6mm × 34mm × 50mm (thickness × width × length). It is a direct replacement for 803450 (8.0×34×50mm) and 853450 (8.5×34×50mm) batteries — slightly thicker but compatible with most devices that have a bit of extra space. Please verify your device’s battery dimensions (8.6×34×50mm), voltage (3.7V), and wiring before purchasing. Pre-attached wires make soldering easier — but installation still requires soldering.
