How long does a Kronobat UPS battery last?

Under normal float use (permanently connected), typical service life is 5 to 7 years, depending on the ambient temperature where the UPS is installed.

Is it compatible with any UPS brand?

Yes, as long as the capacity (Ah) is equal or higher and the physical dimensions match the UPS's battery compartment, regardless of the equipment's brand.

What's the difference between KS7-12, KS17-12, KS50-12 and KS100-12?

Only the capacity (Ah) and therefore the runtime: from 7 Ah for a home PC UPS up to 100 Ah for telecom switchboards or high-power UPS units.

Why can't I use a car battery for the UPS?

Because a starting battery isn't built for continuous float charge and degrades quickly under that regime; the stand-by AGM technology in these batteries is specifically designed for that permanent use.

KRONOBAT UPS: reliable backup during power cuts at the best price

The KRONOBAT UPS range uses stand-by AGM technology, specifically designed to work under continuous float charge (permanently connected to the UPS charger) for years without degrading, unlike a regular cycling battery. With a typical service life of 5-7 years in this regime, it offers the cost-reliability balance a home, SMB or data-centre UPS needs.

KRONOBAT UPS models and applications

KS7-12 (7 Ah) — home UPS for PC, router and home electronics.
KS17-12 (17 Ah) — small office or SMB UPS.
KS50-12 (50 Ah) — server rack UPS.
KS100-12 (100 Ah) — telecom switchboard and higher-power UPS.

How to choose your Kronobat UPS battery

Check the capacity (Ah) and the exact dimensions of the battery fitted in your UPS: replacing it with a higher-Ah unit, if the compartment allows, extends the runtime on each power cut. Use the comparison tool to check at a glance which Kronobat KS model matches your equipment.
