Backup Power Sources

Last Week

We took a break from our usual product updates to share some exciting AFAM news — including recruiting an Auckland-based BDM and opening a new Auckland office! If you missed it, you can catch up here AFAM News & Updates.

This Week: Backup Power Sources

This week we’re talking about backup power sources for the CTU and connected devices. It might not be the flashiest topic, but it’s one of the most important — because getting it wrong can cause real headaches later on.

Backup Power Options

We currently support two types of backup power sources:

• Battery (Sealed Lead Acid, or SLA)
• Super Capacitor

The best option depends on your installation type and how many systems are connected.

SLA Batteries
Invented in the 1970s, the Sealed Lead Acid (SLA) battery became the standard for reliability and consistency. It uses lead plates and an acid-based liquid or gel to store and release charge. Traditional lead acid batteries as a technology were invented in 1859.

Super Capacitors
Super Capacitors work similarly to normal capacitors but are far more efficient at storing and releasing energy. They excel at delivering high currents when needed and aren’t affected by temperature in the same way as SLA batteries.

Battery vs Super Capacitor - Which to Use?

We generally use Super Capacitors when the CTU is installed in-panel and not connected to any secondary system.
For all other installations, a battery is required.

The required battery size depends on the number of connected systems — full details are in our installation instructions. If you’re unsure, our support team is always happy to help.

Battery Quality Matters

Not all batteries are created equal. Even if two look the same, their internal build quality can differ significantly.

When purchasing batteries, stick with reputable brands and suppliers. Check the warranty period — shorter warranties often indicate cheaper, less reliable batteries. While budget options can seem tempting, they often cost more in the long run.

6 Volt Batteries

​Previously, some in-panel installations used two 6V batteries connected in series. However, when the original manufacturer discontinued these batteries, we were unable to find an alternative that met our performance standards.

We now supply a single 12V 2.9Ah battery, which comfortably meets all backup requirements for new installations.

For existing systems, we can still supply 6V replacements in the same form factor, but these now carry a 6-month warranty, reflecting the warranty provided by our supplier.

If you have any questions, our support team can help.

Battery vs Super Capacitor Confusion - Avoid the Mix Up

As we mentioned in a recent Tips & Tricks newsletter, the CTU can use either a battery or a Super Capacitor — never both at the same time.

The Super Capacitor connector includes a detection pin that tells the CTU what’s connected. If both are plugged in, the battery can overcharge and be damaged. Connecting to the wrong port won’t harm the CTU, but it can leave the system without a proper backup.

When in doubt, check your connectors or contact our support team — they’ll help ensure everything’s set up correctly.

Coming Next Week

Next week, we’re diving into Solomon and focusing on features for Service Agents — including how to access them both in the office and on-site (even after hours). We’ll show you what’s available and how these features can make your work smoother and more efficient.
