Rechargeable Battery Pack No name ARB-L40 12000 mAh 7.2 V

The Rechargeable Battery Pack No name ARB-L40 12000 mAh 7.2 V is a high-capacity external power source designed to extend operating time of compatible devices that accept a 7.2 V rechargeable pack. With a nominal voltage of 7.2 V and 12000 mAh capacity, the pack is intended to provide sustained power for equipment used outside fixed power sources. The compact form factor and rechargeable chemistry make it a practical choice for on-site tasks, emergency backup, and longer single-session use where repeated device downtime must be avoided.

Advantages

The battery pack delivers a large energy reserve at a stable nominal voltage, enabling longer runtime compared with lower-capacity cells. Rechargeability reduces the need for disposable batteries and supports repeated use over many charge cycles. The unit’s design focuses on portability and compatibility with devices that accept external 7.2 V packs, simplifying field replacement and minimizing interruptions during work or transport.

Suitable for

• Portable electronic equipment and tools that accept 7.2 V external battery packs
• Field work where mains power is unavailable or impractical
• Backup power for short-term outages or extended single-session tasks
• Applications requiring repeated use and long runtime between charges

Key specifications

• Nominal voltage: 7.2 V
• Capacity: 12000 mAh
• Rechargeable: yes
• Intended use: external battery pack for compatible devices
• Physical characteristic: compact portable pack design

How to use

Before first use, charge the battery pack fully using a compatible charger rated for its voltage and chemistry. Connect the pack to the target device according to the device manufacturer’s instructions, ensuring polarity and connector compatibility. Monitor device operation and battery level as indicated by the device; recharge the pack when capacity is low. Store and transport the battery in a dry, cool place and follow the device’s and charger’s safety guidelines to prevent damage or reduced service life.

Usage recommendations

To maximize service life, avoid deep discharges and recharge the pack after moderate use rather than allowing complete depletion. Use a charger compatible with 7.2 V rechargeable packs and observe manufacturer guidance on charge currents and temperatures. Keep the pack away from heat sources and moisture, and inspect connections before each use.
