2-power 2P-34GKR - Bateria - Bateria 42 mAh 7,4 V

For devices that demand a compact yet dependable power source, the 2-POWER 2P-34GKR battery pack delivers a stable 7.4V with a 42mAh capacity in a lightweight, space-efficient form. Unlike generic coin cells or bulky multi-cell packs, this 2S lithium-ion unit integrates essential protection circuitry, making it a smart choice for replacements in specialty tools, sensors, or portable electronics where space is at a premium.

Highlights

• Lithium-ion chemistry with 2 cells in series for a nominal 7.4V output
• Integrated protection against overcharge, over-discharge, and short circuits
• Compact black housing suitable for tight installation spaces
• Wide operating temperature range: -20°C to 60°C (discharge)
• Rechargeable design for long-term cost efficiency

In daily use

Installation is straightforward: the pack’s compact footprint and standard barrel-style terminals allow it to fit into most device battery compartments without modification. Once in place, the built-in protection circuit continuously monitors voltage and current, preventing damage from common misuse such as leaving the device plugged in overnight or exposing it to temperature swings. The 42mAh capacity is ideal for low-drain applications—think backup memory, small sensors, or handheld instruments—where a full-size battery would be overkill. Recharging is simple with any compatible 7.4V Li-ion charger, and the pack retains its charge well during storage, thanks to low self-discharge characteristics.
