Battery Varta 4022211501 Alkaline 9 V 580 mAh (alkaline)

Varta 9V Alkaline Block is a general-purpose 9‑volt alkaline-manganese battery supplied in a bulk pack of 272 units. It is designed to deliver the stable nominal voltage and shelf life typical of alkaline chemistry for everyday electronic and household devices that require a 9 V supply. The cell is suitable for intermittent and continuous loads found in smoke alarms, test instruments, portable audio equipment and other small appliances.

Advantages

The alkaline-manganese chemistry provides consistent voltage under typical loads and a long storage life compared with older zinc-carbon types. Supplied as a large pack of 272 units, this offering reduces the need for frequent reordering for high-volume users such as service departments, installers and institutions. The standardized 9 V block format fits into common battery compartments and connectors used by many handheld devices and detection equipment.

Suitable for

• Smoke detectors and carbon monoxide alarms
• Multimeters and handheld test equipment
• Portable radios and audio transmitters
• Wireless microphones and small stage equipment
• Educational electronics kits and hobby projects

When it may not be suitable

This alkaline 9 V battery is intended for general-purpose applications. It may not be the best choice for devices that demand very high continuous currents or for mission-critical systems that require the longer runtime and stable voltage profile of rechargeable chemistries such as NiMH or lithium primary cells. For low-temperature operation or very long unattended service intervals, consider batteries specifically rated for those conditions.

Key specifications

• Chemistry: alkaline-manganese
• Nominal voltage: 9 volts
• Form factor: 9 V rectangular block (standard terminals)
• Intended use: general-purpose electronic and household devices
• Pack quantity: 272 units (bulk pack)

How to use

Install the 9 V block with correct polarity into the device holder, ensuring the positive and negative terminals align with the device connectors. For devices with removable covers, secure the cover after insertion to prevent accidental disconnection. When replacing multiple batteries in equipment racks or distribution points, rotate stock using older packs first to keep overall inventory fresh. Dispose of used alkaline batteries according to local regulations or recycle where facilities exist.

What to consider before purchase

• Verify device compatibility with standard 9 V block batteries and terminal type.
• Assess whether a bulk pack of 272 units matches your consumption rate and storage capacity.
• Consider storage conditions: cool, dry place to preserve shelf life.
• If device requires very high current or rechargeable operation, evaluate alternative chemistries.

Usage recommendations

For smoke detectors and safety devices, follow manufacturer replacement intervals and test alarms regularly after installing new batteries. Store unopened packs away from heat sources and direct sunlight to maintain performance. For professional or institutional use, label batches with receipt dates to control rotation and minimise expired inventory.
