2-Power pääakku - akku - 50 mAh (2P-5B10W13907)

For devices that demand a compact, reliable power source, the 2-Power 2P-5B10W13907 Main Battery Pack steps in where standard AA or AAA cells fall short. This lithium-ion pouch cell delivers a stable 3.7V output in a slim, lightweight form factor, making it ideal for miniature electronics, wearables, and embedded projects. Unlike generic coin cells, it offers rechargeability and integrated protection, so you can power your device repeatedly without worry.

Highlights

• Lithium-ion (Li-ion) chemistry with 50 mAh capacity and 3.7 V nominal voltage
• Integrated PCB protection against overcharge, over-discharge, overcurrent, and short circuit
• Rechargeable design supports up to 300–500 charge cycles
• Compact pouch/prismatic form factor for space-constrained applications
• Operating temperature range from -20°C to 60°C, storage from -20°C to 45°C
• CE and RoHS compliant for safety and environmental standards

In daily use

Whether you're replacing a worn-out cell in a Bluetooth tracker, a tiny remote sensor, or a custom IoT device, this battery provides consistent power in a minimal footprint. The built-in protection circuit ensures safe charging and discharging, while the 0.5C maximum charging current (25 mA) allows for gentle, efficient recharging with a compatible charger. Its black and silver finish blends discreetly into most device housings.
