2-power pääakku - akku - 46 mAh (2P-FRU00HW029)

For ultra-compact devices where every gram matters, this 2-POWER main battery pack delivers a dependable 46 mAh in a single Li-Po pouch cell. Unlike bulky multi-cell packs, it prioritises a minimal footprint and stable 3.7 V output, making it a practical replacement for wearables, IoT sensors, and Bluetooth accessories that demand a slim energy source.

Highlights

• Lithium Polymer chemistry for a lightweight, flexible form factor
• Nominal 3.7 V output with 0.17 Wh energy rating
• Rechargeable design with 300–500 typical cycles
• Operating temperature from -20°C to 60°C (discharge)
• Low self-discharge of less than 5% per month

In daily use

The pouch cell format slips easily into tight enclosures, and the 1C discharge capability (46 mA continuous) suits low-power electronics that run for extended periods between charges. Charging is straightforward with a 0.5C current limit of 23 mA and a 4.2 V voltage cap, while the 3.0 V cut-off helps protect cell health over time.
