Varta NiMH rechargeable battery V15H 1.2 V 16 mAh

The Varta V15H is a high-performance and very compact nickel metal hydride battery (NiMH) in button cell design, which was specially developed for miniaturised industrial applications. It offers a nominal voltage of 1.2 V and a typical capacity of 16 mAh. Thanks to its high cycle stability and reliability, the V15H is the ideal choice for memory backup solutions (memory back up), real-time clocks (RTC), and other applications that require a rechargeable and permanent power supply in the smallest of spaces.

Highlights at a glance

• Rechargeable: Long-life nickel metal hydride technology for hundreds of charging cycles
• Miniaturised: Very compact design with only 11.5 mm diameter
• Reliable: Designed for long-term use in industrial environments
• Long-term charge resistant: Ideal for permanent use in buffer applications
• Solderable: Often available in versions with solder terminals for permanent installation

Powerful for miniaturised buffer applications

The Varta V15H rechargeable battery was specially designed for use in professional electronics where space available is extremely limited. It is ideal for buffering memories (SRAM, DRAM) and real-time clocks in industrial control systems (PLC), medical devices, measuring instruments and communication modules. Its robust design ensures data integrity even if the primary power supply fails.

Reliable NiMH technology

The nickel metal hydride technology used stands for high energy density, good cycle stability, and a more environmentally friendly alternative to older NiCd batteries. Varta rechargeable batteries are characterised by high manufacturing quality, which ensures low self-discharge in the charged state and long service life even under demanding charging and discharging conditions. This makes them an economical and sustainable energy solution.

Efficiency and safety with system

Varta rechargeable batteries are subject to strict quality controls to ensure consistently high performance and maximum safety. The V15H is designed for a long service life and offers high reliability in continuous operation. For optimum performance and service life, it is recommended to use a suitable charging circuit that protects the battery from overcharging.

FAQs about the Varta V15H NiMH battery

Is this battery a direct replacement for a battery?

No, the V15H is a rechargeable battery with a nominal voltage of 1.2 V. It may only be used in devices that are explicitly designed for the use of NiMH batteries and have a corresponding charging circuit. Use in devices for 1.5 V or 3.0 V primary batteries is not possible.

How often can the V15H battery be recharged?

The cycle stability of a NiMH battery depends greatly on the operating conditions such as charging current, depth of discharge and temperature. Under optimal conditions, however, the Varta V15H can achieve several hundred charge and discharge cycles.

What does memory back up application mean?

Memory back up means memory retention. The battery supplies a memory module (e.g. RAM) or a real-time clock (RTC) with power when the main device is switched off. In this way, important data, configurations or the time are retained.

How must this battery be disposed of?

As a rechargeable battery, the V15H must not be disposed of with household waste. Please take it to the special battery and rechargeable battery collection points in shops or at municipal recycling points to ensure proper recycling.
