Question: Hi,I've been installing alarm batteries for forty years. For the past twenty five years, our company has relied on intelligent battery test equipment to ensure the that our customers are getting good batteries in all their equipment and that we are getting more testing data then just voltage readings. We use Powersonic PS1270-F1 and PS12180-NB as the standard go to batteries. They would usually last five years in most cases, except in extreme heat. That usually cuts the life of the battery by a year or two. Starting in 2022, our Power Sonic 7ah batteries were testing at 4.0-4.3 ah right out of the box and once installed, under 4ah, one year later. They used to be 7ah-9ah right out of the box and may or may not test under 4.4 ah after five years, but we replace them due to the age. 7ah batteries are supposed to be replaced at 4.4ah and under. We had similar issues with the 18ah as well, which have to be replaced at or under 11.7 ah or close to that. After pleading with our management, they are going to allow me to source out a better quality brand. ADI has multiple brands, like the well know Yuasa. Obviously Power Sonic batteries have changed in some form or fashion of origin, or manufacturing, etc. I am going to purchase some Duracell 12v 7ah and 12v 18ah batteries from Batteries Plus and test them right at the store. They are forty dollars each for the 7ah. If they read like they should I am going to install them at one of our customers properties, see how they do for the next several years. Does anyone out there that tests their batteries annually with something like the ACT intelligent battery tester, have any recommendations for good quality, long lasting alarm batteries?

You're experiencing a frustrating situation, and your proactive approach to finding a better alternative is commendable. The decline in Power Sonic battery performance since 2022 is a significant concern. Here's some advice and recommendations, focusing on your situation and the tools you use

Understanding the Problem:
Consistency is Key

The fact that
both your 7Ah and 18Ah Power Sonic batteries are exhibiting degraded performance out of the box strongly suggests a systemic issue, whether it's manufacturing, materials, storage, or even counterfeiting.

ACT Tester Data is Gold

You're wise to leverage your ACT tester. The Ah (Amp-hour) readings are crucial. Voltage alone is misleading.

Heat's Impact

You're right about heat's detrimental effect on battery life. Good brands will
mitigate this somewhat, but it's always a factor. Consider strategies like better ventilation if possible at customer sites.

Recommendations for Alternative Brands and Strategies

Given your reliance on the ACT tester and your experience, I'd recommend these brands, along with considerations for testing and deployment:1.

Yuasa



Pros

You mentioned it, and for good reason. Yuasa is a reputable brand known for its consistent quality and reliability. They are generally considered a premium option. They are widely available and provide consistent power.

Cons

They can be more expensive than other brands.


Testing

Thoroughly test the Yuasa batteries with your ACT tester before purchase (if possible) and definitely before installation. Make sure they meet or exceed their rated Ah capacity.

Part Numbers

Be sure to use the correct part number for your equipment. The Yuasa NP7-12 (7Ah) and NP18-12 (18Ah) are common equivalents to the PS1270 and PS12180.2.

MK Battery/Deka



Pros

MK Battery (Deka) is another well-regarded brand, especially for deep-cycle applications. Their sealed lead-acid (SLA) batteries are known for durability and longevity.

Cons

Availability can be a bit more limited than Yuasa.


Testing

Same as Yuasa – rigorous ACT testing.

Part Numbers

Consider the MK ES7-12 (7Ah) and the MK ES18-12 (18Ah).3.

Panasonic



Pros

Panasonic is a globally recognized electronics company and also manufactures reliable SLA batteries. They are widely used in various applications.

Cons

Panasonic may not be as common in alarm system installations as some other brands.


Testing

Before committing to Panasonic, test their Ah performance thoroughly.

Part Numbers

Look for the LC-R127R2P (7Ah) and LC-R1217P (18Ah) or similar.4.

Duracell



Pros

Readily Available (Batteries Plus). The brand name is well-known, which may be a selling point for customers.

Cons

The quality of Duracell SLA batteries (often rebranded from other manufacturers) can be variable. Testing is
absolutely crucial before relying on them.

Testing

Your plan to test them at Batteries Plus is excellent. Record the initial Ah reading from the ACT tester and then monitor them closely after installation.

Part Numbers

Ensure the Duracell batteries have the correct voltage and terminal type.

Key Testing Procedures



Initial Testing

As you're already planning, test the Ah capacity of the batteries immediately upon receiving them. This establishes a baseline and identifies any that are already underperforming.

Load Testing

While the Ah reading is critical, also perform a load test. This simulates the battery discharging under a load (like an alarm system in standby or during an alarm event). The ACT tester should be able to do this. Check the voltage drop under load. A good battery will maintain a relatively stable voltage.


Regular Testing

After installation, test the batteries annually, as you've been doing. Track the Ah readings over time to identify degradation patterns.

Temperature Monitoring

If possible, monitor the ambient temperature around the battery. If heat is a significant factor, consider recommending battery boxes that provide some insulation and ventilation.


Document Everything

Keep detailed records of battery brand, model, purchase date, initial Ah reading, subsequent Ah readings, installation location, and any relevant environmental factors (temperature). This data will be invaluable in determining the best battery brand for your needs.

Additional Tips



Check Battery Freshness

SLA batteries have a shelf life. Look for a date code on the battery to ensure it hasn't been sitting for an extended period. Ask the supplier how they manage inventory.


Negotiate with Suppliers

Leverage your volume and experience to negotiate better pricing with suppliers.

Pilot Program

Instead of immediately switching all customers to a new brand, consider a pilot program. Install the new batteries at a select group of customers and closely monitor their performance over several years. This will give you solid data to justify a larger-scale change.


Consider Battery Chargers

Are your alarm systems using optimal charging profiles? An under- or over-charging system can dramatically shorten battery life. It might be worth investigating the charging systems themselves.

Talk to Other Alarm Companies

Network with other alarm installation companies and ask about their experiences with different battery brands.


Consult with Battery Manufacturers

Reach out to the technical support departments of the battery manufacturers you're considering. Explain your application and testing procedures, and ask for their recommendations.

Addressing the Power Sonic Issue



Contact Power Sonic

If you haven't already, contact Power Sonic and explain the performance issues you're experiencing. Provide them with the date codes and test data. They may be able to offer an explanation or compensation.


Consider Counterfeiting:
Although less likely, there is a possibility of counterfeit batteries. Purchase from reputable distributors and compare the battery's appearance and labeling to known authentic batteries.By following these recommendations, you can make an informed decision and provide your customers with reliable, long-lasting alarm batteries.
