Is your APC ES 550 UPS beeping at you?

It's probably time for a new battery.

Here's a direct replacement from Ultra Max that'll get your backup power running like new again.

It's a 12-volt, 7 amp-hour sealed lead acid battery—the exact specs you need.

The model is SLAUMXNP7-12, and it's made to fit perfectly inside your APC unit.
Just pop the old one out, connect the terminals, and you're good to go.

It comes with a 1-year warranty and is great for keeping your computer or other electronics safe during a power flicker.

Made in Taiwan, this battery is a solid, reliable choice.
Silence that beeping for good!
