Universal Household Battery Tester

The Faithfull Battery Tester is designed to check many of the most common battery sizes found in everyday household equipment.

Its adjustable design makes it suitable for a range of cylindrical, rectangular and compatible button cell batteries.

This versatility makes it useful for households that regularly use several different battery types.

AA Battery Tester

AA batteries are commonly used in household electronics, toys, torches and other portable devices.

The Faithfull Battery Tester allows you to check the condition of AA batteries quickly using its analogue needle display.

This helps you identify batteries that may need replacing before returning them to a device.

AAA Battery Tester

AAA batteries are frequently used in remote controls, small electronics and other compact devices.

With the Faithfull Battery Tester, you can check whether a compatible AAA battery has a good, low or replacement-required power indication.

C & D Battery Tester

Larger C and D batteries are often found in torches, portable radios and other battery-powered equipment.

The adjustable testing arm accommodates both C and D batteries, making the tester useful for checking larger household battery sizes.

9V Battery Tester

The Faithfull Battery Tester is compatible with 9V 6F22 batteries.

This makes it useful for checking the battery condition of compatible 9V batteries used in various household and electronic devices.

Always follow the equipment manufacturer's guidance for battery replacement, particularly for safety-critical devices such as smoke alarms.

1.5V Button Cell Battery Tester

In addition to common cylindrical batteries, the Faithfull Battery Tester can check 1.5V button cell batteries.

These small batteries are used in various compact electronic devices.

Check the battery type and voltage before testing, as not all button cell batteries are 1.5V.

Suitable for Rechargeable Batteries

The Faithfull Battery Tester can be used with compatible rechargeable batteries, providing a quick indication of their condition.

This makes it useful for checking rechargeable batteries before use or after charging.

The analogue display provides an approximate power indication rather than a precise measurement of remaining battery capacity or long-term battery health.

Easy-to-Read Analogue Needle Display

The tester features a simple analogue needle indicator that displays battery condition.

The needle moves to indicate one of three general levels:

• Good: The battery shows a usable power indication.

• Low: The battery has a reduced power indication.

• Replace: The battery has a low reading and may require replacement or recharging, where applicable.

This straightforward display makes the tester easy to use without complicated settings or digital menus.

Adjustable Testing Arm

The adjustable testing arm allows the device to accommodate different battery sizes.

This makes it convenient to switch between common battery types without needing a separate tester for each size.

Compact Folding Design

When testing is complete, the adjustable arm can be folded down for convenient storage.

The compact design makes the Faithfull Battery Tester easy to keep in a toolbox, kitchen drawer, utility cupboard or workshop.

Powered by the Battery Being Tested

The Faithfull Battery Tester operates using the power supplied by the battery under test.

This means no separate battery is required to power the tester.

However, testing places a load on the battery, so readings should be taken quickly to avoid unnecessary battery drain.

Helps Reduce Unnecessary Battery Waste

It can be difficult to know whether a battery is depleted simply by looking at it.

The Faithfull Battery Tester helps identify batteries that still show usable power, reducing the likelihood of discarding batteries unnecessarily.

This is particularly useful when sorting batteries removed from household devices.

Ideal for Home, Office & Workshop Use

The Faithfull Battery Tester is a practical accessory for anyone who regularly uses battery-powered equipment.

It is particularly useful for:

• Household battery checks

• Remote control batteries

• Torch batteries

• Toy batteries

• Portable electronic devices

• Workshop battery storage

• Office equipment

• Compatible rechargeable batteries

How to Use

1. Identify the battery type and confirm it is compatible with the tester.

2. For AA, AAA, C or D batteries, position the battery against the appropriate contacts using the adjustable arm.

3. For 9V 6F22 or 1.5V button cell batteries, use the corresponding test contacts.

4. Ensure the battery terminals are correctly aligned with the tester contacts.

5. Observe the analogue needle display.

6. Check whether the reading indicates good, low or replacement required.

7. Remove the battery promptly after taking the reading.

8. Fold down the adjustable arm when finished.

Important: Keep testing time as short as possible. The tester draws power from the battery being checked, and prolonged testing can cause unnecessary battery drain.
