Batteries for Hotel & Lodging Smoke AlarmsIn our previous blog, we discussed how ‘dead batteries caused 24% of all smoke alarm failures in 2015’, which means that Fire Protection Groups and Fire Departments must be cautious when recommending the best batteries.  Many factors must be considered, from high performance to longevity.

Smoke Alarm Batteries - CR123A and 9VUltralife design and manufacture two main types of non-rechargeable battery that are suitable for smoke detectors; 3V CR123As and Lithium 9V.  Here are ten reasons why Fire Chiefs and Protection Groups can feel confident in recommending them:

1)  Industry Experience

Since Ultralife Corporation was founded, the company has been manufacturing the 9V battery for use in smoke alarms.  This technical expertise has been used to develop the new CR123A (UB123A) 3V battery.

The new UB123A will be manufactured in the US, where Ultralife has 28 years of industry experience.

9 Volt

More than 100 million Ultralife 9V batteries have been sold during 27 years of manufacturing.

2)  Innovative Mechanical Design

Ultralife undertake continuous research and development to improve battery design, which – in turn – enhances performance.

To increase capacity, the UB123A has internal spiral construction that improves overall performance.

Originally constructed using cylindrical cells in a square formation, Ultralife’s engineers realized this wasted vital space, so developed today’s thin cell version as a pouch with square cells.

3)  Consumer Replaceable

Many smoke detectors come supplied with a battery from the manufacturer that is often not consumer replaceable, which is why both the CR123A and Lithium 9V have a long service life, similar to the lifetime of the product.  However, for smoke detectors that allow batteries to be changed by the end user, Ultralife ensure that the CR123A and Lithium 9V are suitable replacements.

  CR123A

Some of the CR123As offered by Ultralife are manufactured in China, making them a lower cost solution for retail applications (as mentioned above, the UB123A will be made in the US).

9 Volt

Ultralife’s 9V measures the same size as a standard alkaline battery, meeting ANSI Alkaline 1604 specifications.

4)  Shelf Life

To allow Ultralife’s batteries to be stored as back-ups, an excellent storage life is offered.

  CR123A

The UB123A can also be stored for up to 10 years.

9 Volt

Tests have shown that the 9V can be stored for more than ten years without compromising performance.

5)  Service Life

Choosing a battery with a long service life means that the smoke alarm should not need changing as frequently, giving added peace of mind.

  CR123A  
2 Tick Boxes

The CR17335 has a battery life higher than 10 years, depending on the application.

9 Volt

In most ionization-type smoke detectors, the 9V has an operational life of up to 10 years.

6)  Wide Temperature Range

As smoke detectors may be required for use in hot and cold environments; the battery’s ability to perform in varied temperatures is vital.

  CR123A  
2 Tick Boxes

The new UB123A battery has an operating temperature range of -20 to 72°C and a storage temperature range of -40 to 60°C.

9 Volt

Lithium 9V’s operating temperature range is between -20 and 60°C, with a storage temperature range of -40 to 60°C.

7)  Safety Features

In addition to being able to perform in a variety of temperatures, Ultralife batteries are protected against reasonable and foreseeable misuse.

  CR123A

Among the safety features is a Positive Temperature Coefficient (PTC) safety device to limit current during short circuit conditions.

9 Volt

Safety measures include a shutdown separator internal to each of the three cells and a Polymer Positive Temperature Coefficient (PPTC).

8)  High Performance

When the smoke detector is triggered, it needs to be relied upon to perform effectively.

  CR123A

The UB123A is set to provide the highest capacity in the industry, 1800mAh.

9 Volt

Whilst the competition offers Lithium 9V products with 800mAh of capacity, Ultralife offer 1200mAh or 50% more energy.

9)  Certified

Do not just take our word for it that the batteries deliver to a high standard.  Both the CR123A and 9V have been pre-qualified to internationally recognized standards.

  CR123A  
2 Tick Boxes

Certifications that come as standard include UL 1642, UN 38.3 and IEC 60086-4:2014

9 Volt

Pre-qualified to meet UN 38.3, UL 2054, UL 217 and IEC 60086-4:2014

10)  Suitable for Other Applications

Providing better value for money, customers who buy Ultralife batteries can also use them in a wide range of additional applications.

  CR123A  
2 Tick Boxes

Many portable products can be powered with this battery, such as digital video cameras, portable lights, security systems, ELTs, handheld electronics and Internet of Things (IoT) devices.

9 Volt

Lithium 9V is suitable for use in rugged handheld devices, telematics, instrumentation equipment, ELTs, security sensors, metering systems, wearable Medtech and much more.

 

These are just ten of the reasons that Ultralife CR123A and Lithium 9V batteries are highly suited for use in smoke alarms and other devices.  If you are a member of a Fire Protection Group or work for a Fire Department and would like any further information, please
