UPS Replacement Batteries

When the UPS under your desk starts beeping or fails its self-test, it's almost never the whole unit that's done - it's the battery inside it. This is the category for UPS battery replacement: the sealed AGM batteries that bring a small office UPS back to full runtime. Most of the folks we help here run a small business or office in and around Willoughby, and they bring us one of two things: the whole unit, or just the hot-swappable cartridge that pulls out of it. Either way, we put the right batteries in and hand it back ready to protect your equipment again.

One thing to know before you order a replacement: a UPS doesn't pull on its battery the way a car does. It sits and floats for months, then dumps a hard burst of current the second the power drops. That's a high-rate discharge job, and it's the reason we stock purpose-built UPS batteries rather than general-purpose cells that look identical on the spec sheet but fade fast under inverter load. Get the wrong one and you'll be back here in a year wondering why your runtime collapsed. We've done enough of these over 36 years at one Willoughby bench to steer you right the first time.

UPS Replacement Batteries for APC, CyberPower, Eaton, and More

• Three common sizes cover most small units: 12V 9Ah, 12V 7Ah, and 12V 5Ah, fitting the majority of desktop and small tower UPS systems.
• High-rate discharge AGM, built for UPS duty. General-purpose batteries read the same on paper but won't hold up to the inverter draw.
• Fits units from APC, Schneider, Eaton, CyberPower, and Tripp Lite. Bring the model number or the unit itself and we'll match it.
• Free battery swap in our shop when you buy the batteries from us. Drop off the whole unit or just the cartridge.
• 1-year full replacement warranty on every battery in this category.
• Honest diagnosis: about 1 in 10 times the battery isn't the real problem, and we'll tell you rather than sell you one you don't need.

Plenty of the small offices we keep running are right here in Lake County, from Willoughby out toward Mentor and Painesville. If you already know your size, we'll have it on the shelf; if you're not sure what's in there, bring the unit by and we'll open it up and check.

DC power is the only thing we've done from this Willoughby shop for 36 years, so you're talking to people who specialize in it, not a counter that's guessing from a screen.

Bring your UPS by the shop on Vine St. or call us at 440-942-2555. We'll get the right battery in it and make sure that's actually what the unit needed before you pay for anything.
