2-power Main Battery Pack - Akku - 54 mAh (2P-451-BBTW)

For technicians and device refurbishers, the 2-POWER 2P-451-BBTW stands out as a precision-engineered single-cell Li-Ion pack that delivers exactly 3.7V and 54mAh — a niche capacity often missing from generic multi-purpose batteries. Instead of bulky adapters or universal cells, this prismatic unit integrates directly into compact electronics, preserving the original form factor and eliminating guesswork during swap-outs.

Highlights

• Lithium-Ion chemistry with 3.7V nominal voltage and 54mAh capacity
• Prismatic form factor with integrated contacts for solder-free installation
• Rated for up to 500 charge/discharge cycles
• Built-in protection against overcharge, over-discharge, and short circuit
• CE and RoHS certified; polymer casing in black

In daily use

Whether you are servicing a handheld scanner, a small IoT sensor, or a wearable device, this battery slots in as an internal replacement without requiring connector modifications. The integrated contacts ensure a stable connection, while the protection circuitry guards against voltage spikes and deep discharge. Operating from 0°C to 45°C, it handles typical indoor and light outdoor environments; storage down to -20°C allows safe warehousing before deployment. The 0.2Wh energy rating is modest but perfectly matched to low-drain devices where longevity and reliability matter more than raw capacity.
