Button cell battery Varta V150H-SLF++/- 150 mAh 1.2 V rechargeable nickel-metal hydride

Varta V150H-SLF++/- is a rechargeable button cell based on nickel‑metal hydride chemistry, offering a nominal capacity of 150 mAh and a nominal voltage of 1.2 V. Designed for compact, low‑voltage electronics, this cell delivers stable output suited to devices where a small form factor and repeated rechargeability are required. The construction supports multiple charge/discharge cycles while maintaining consistent performance for applications with moderate continuous or intermittent drain.

Advantages

The nickel‑metal hydride chemistry provides reliable voltage stability and a higher usable capacity compared with older rechargeable chemistries at similar sizes. Its compact button format reduces space requirements inside small devices. Rechargeability reduces waste and lowers long‑term operating cost versus single‑use cells. The cell tolerates typical charge and discharge cycles expected in consumer and professional compact electronics.

Suitable for

• Watches and small timekeeping devices
• Medical instruments and portable healthcare sensors
• Memory backup modules and RTC (real‑time clock) backup
• Compact sensors, transmitters and measurement tools

Key specifications

• Chemistry: Nickel‑metal hydride (NiMH)
• Nominal capacity: 150 mAh
• Nominal voltage: 1.2 V
• Cell type: Button cell / coin cell form factor
• Rechargeable: Yes — designed for multiple charge/discharge cycles

How to use

Install the cell into the device following the manufacturer’s polarity markings and contact orientation. Charge the cell using a charger compatible with nickel‑metal hydride button cells and observe the charger’s recommended current and charging method. Avoid charging with inappropriate high currents or chargers designed for other chemistries. Replace the cell when capacity or runtime no longer meets the device requirements.

Recommendations

Store unused cells in a cool, dry place and avoid prolonged exposure to high temperatures. Use a charger specified for NiMH button cells and follow device manufacturer guidelines for replacement intervals. Dispose or recycle according to local regulations for rechargeable batteries.
