Gombíková batéria Varta V3/15H-SLF++/- 15 mAh 3,6 V

Varta V3/15H-SLF++/- button cell battery provides a nominal voltage of 3.6 V and a capacity of 15 mAh in a compact miniature package. It is engineered for applications that require a small, stable low-current power source over extended periods. The battery is suitable for maintaining memory backup, powering real-time clocks, low-power sensors and similar electronic modules where long-term, predictable voltage is important.

Advantages

The cell delivers a consistent 3.6 V output with low self-discharge characteristics, enabling long shelf life and reliable operation in standby or low-drain devices. Its small form factor allows installation in confined spaces and on compact circuit boards. The chemistry and construction are optimized for stable voltage under light continuous draw or occasional pulses typical for memory backup and clock circuits.

Suitable for

• Memory backup in electronic devices and microcontrollers
• Real-time clocks and calendar modules
• Low-power sensors and telemetry modules
• Small remote controls and alarm system memory
• Industrial and consumer devices requiring a compact long-term power source

Key specifications

• Nominal voltage: 3.6 V
• Typical capacity: 15 mAh
• Cell type: miniature button cell
• Intended discharge: low-drain / standby and memory backup applications
• Physical advantages: compact size suitable for tight mounting spaces

How to use

Install the battery in the device’s dedicated holder or contact pads observing correct polarity. Ensure contacts are clean and free of corrosion before insertion. For long-term backup use, check device specifications for allowed float charging or replacement intervals; most applications rely on the cell as a primary non-rechargeable source. When replacing, dispose of the spent cell according to local battery recycling regulations.

Recommendations

Store unused batteries in a cool, dry place away from direct sunlight and temperatures above recommended storage limits. Avoid short-circuiting terminals and prolonged exposure to high temperatures. Replace the cell with the same type to maintain device functionality and to prevent damage to backup circuits.
