4V 4Ah Rechargeable battery

4V 4Ah Rechargeable Battery for Backup Power

The 4V 4Ah Rechargeable Battery is a compact rechargeable battery designed for equipment that requires a 4-volt, 4Ah power source. Its compact format makes it suitable for compatible electronic devices where a rechargeable backup battery is required.

This type of battery is commonly used in digital weighing scales, electronic scales, emergency lighting, alarm systems, security equipment and other compatible low-voltage devices.

Before purchasing a replacement battery, always confirm that your equipment requires 4V and 4Ah, and check the physical dimensions and terminal configuration.

4V Voltage and 4Ah Capacity

The battery has a nominal voltage of 4V and a capacity of 4Ah.

The 4Ah rating describes the battery’s rated charge capacity under specified testing conditions. Actual operating time will depend on the equipment connected to the battery, its power consumption, battery condition, charging system and operating conditions.

For this reason, a 4V 4Ah battery should only be used in equipment designed for this voltage and capacity.

Rechargeable Sealed Battery

This battery format is commonly manufactured as a sealed lead-acid/VRLA battery, providing rechargeable power without the routine electrolyte maintenance associated with conventional flooded lead-acid batteries. Published 4V 4Ah models include sealed lead-acid and VRLA designs.

The sealed construction makes this battery practical for enclosed electronic equipment where a compact rechargeable power source is required.

Ideal for Digital Weighing Scales

One of the particularly relevant applications for a 4V 4Ah Rechargeable Battery is digital weighing equipment.

4V 4Ah batteries are specifically sold for compatible digital weighing scales, electronic scales and weighing balances.

This makes the battery useful as a replacement where an existing weighing scale uses a 4V 4Ah rechargeable battery.

Before replacing the battery in a weighing scale, compare the existing battery’s voltage, capacity, dimensions and terminals.

Suitable for Emergency Lighting

Compatible emergency-lighting equipment can use rechargeable batteries to provide backup power when normal electricity is unavailable.

A 4V 4Ah battery can therefore be suitable for emergency-lighting equipment specifically designed around this battery specification. Some 4V 4Ah sealed lead-acid batteries are listed for emergency lighting applications.

The actual backup duration depends on the power consumption of the lighting equipment.

Suitable for Alarm and Security Systems

The 4V 4Ah Rechargeable Battery can also be used in compatible alarm and security equipment.

Published 4V 4Ah VRLA battery specifications include alarm systems and low-voltage backup devices among their applications.

Always verify the equipment’s original battery specification before installing a replacement.

Compact Backup Power Solution

The compact format of a 4V 4Ah battery makes it suitable for equipment with limited battery-compartment space.

Common 4V 4Ah sealed lead-acid models are available in compact dimensions around 47–48mm wide/deep and approximately 100–103mm high, although dimensions vary between manufacturers.

Do not rely on these general dimensions when ordering a replacement. Check your exact battery and equipment first.

Common Applications

These are common applications for this battery type; compatibility must still be confirmed for the specific equipment. Specifications
