Product Description

Reliable Backup When Every Second Counts

When the power goes out, you need to know that your home security system or medical equipment will continue to function without a hitch. The SLA-12V2-9 is a 12-volt, 2.9 amp-hour battery specifically designed for "standby" applications. It acts as a silent guardian for your home, providing the necessary energy to fire alarms, burglar alarms, and emergency exit signs so you are never left in the dark.

Specifically Built for Medical and Security Needs

This "block" style battery is a standard fit for many specialized devices, particularly medical patient lifts and aspirators. Because it uses Absorbed Glass Mat (AGM) technology, it is completely sealed and maintenance-free. You will never have to worry about messy acid leaks or checking fluid levels. Its spill-proof design allows it to operate in various positions, making it ideal for the tight compartments found in security panels and medical housings.

The Durable Choice for Long-Term Performance

We understand that you want a battery you can install and then forget about for years. The SLA-12V2-9 is built with a rugged, impact-resistant case that handles vibrations and daily wear with ease. With a low self-discharge rate, it stays ready for action even during long periods of inactivity. It is a simple, cost-effective way to ensure your most important safety devices are always powered up.

  • Universal 12V 2.9Ah capacity provides long-lasting backup power.
  • F1-style terminals (0.187 inches wide) ensure a quick and secure slide-on connection.
  • Advanced AGM design is safer for indoor use than traditional flooded batteries.
  • Rugged construction resists heat and shock to extend the life of the battery.

Frequently Asked Questions

What are the physical dimensions of the SLA-12V2-9?

A: This battery measures approximately 3.08 inches long, 2.17 inches wide, and has a height of 3.86 inches. The total height, including the terminals, is approximately 4.21 inches.

How do I know if I have the right terminals?

A: The SLA-12V2-9 comes with F1 terminals, which are the smaller "slide-on" tabs measuring 0.187 inches wide. These are the most common terminals for home alarm systems and small medical devices. If your connection is wider (0.250 inches), you may need an F2 terminal adapter.

Is this battery safe to use indoors?

A: Yes. Because this is a Sealed Lead Acid (SLA) battery using AGM technology, it does not release dangerous gases under normal charging conditions and cannot leak acid, making it perfectly safe for closets, basements, and bedrooms.

Can this battery replace a 2.8Ah or 3.0Ah battery?

A: Yes. As long as the voltage is 12V and the physical dimensions fit your battery compartment, a 2.9Ah battery can safely replace models labeled as 2.8Ah or 3.0Ah.

Bought this battery for my Sears Craftsman walk behind lawnmower. It was the right size and now I can start my mower with the turn of a key.

Used this battery to replace one that went bad in my Ion Sport speaker. So far it has been great. Battery Mart was easy to work with and offered great fast shipping with UPS.

I got this battery for an electric start walk behind mower. After installing it the engine turned over great and started well. I couldn't find any charge ports in the wire harness, so I guess the engine charges the battery, unusual for a walk behind mower. So far every time I start the mower the battery has the stuff to start it.
