The version I have the battery is no longer replaceable. APC updated the unit to use batteries that are not replaceable. Not sure what the size was in the older versions.
Sorry, there was a problem. Please try again later.The APC BE600M1 uses a 12V 6.5Ah sealed lead-acid battery—not gel. This type of battery is common in compact UPS units and is designed for reliable backup power and safe indoor use. The battery is user-replaceable and typically lasts 3–5 years, depending on usage and environment. As for why it’s not listed in the specs: sellers often focus on output capacity (600VA / 330W) rather than internal battery details in retail listings. You can find the battery specs in the user manual or APC's official product page.
