Backup Batteries

A backup battery is the part of a UPS that does the actual work of bridging a power cut. The UPS electronics switch to battery power when the mains fails, and the battery decides how long the protected device keeps running. A larger battery means a longer bridge, but it also means a larger, heavier unit and a longer recharge time once the mains returns. Understanding that trade-off is the core of choosing backup power, and it is why this site treats battery capacity as a planning question rather than a single number to maximise.

Richroc lists backup battery as its second main line, alongside mini UPS. The company's store profile records it as a Verified Custom Manufacturer, with finished product inspection and full customisation capability cited there as findings of an independent third-party verification report. As with the mini UPS line, no individual backup battery model on this site carries a published specification sheet, so this page stays at category level. It describes what backup batteries are for, how they relate to mini UPS units, and how to think about running time, without presenting a specification table for a named model.

The relationship between a mini UPS and a backup battery is often misunderstood. In most small systems the two are one product: the UPS contains the battery, the charging circuit, and the switching electronics in a single box. A separate backup battery makes sense when the battery must be larger than the UPS housing allows, when batteries must be replaced independently of the electronics, or when one battery must serve several devices. The blog post on whether a mini UPS battery can be replaced covers the maintenance side of that question, including the general precautions for handling and replacing batteries.

Running time is the figure buyers ask about first, and it is also the figure most often quoted without its conditions. A battery that runs a small router for many hours may run a camera and a switch together for far less, because running time depends on the total power drawn, not on the battery alone. The capacity guides on this site explain that relationship in general terms: capacity figures that appear in marketplace listing titles, such as 10400mAh, 13500mAh, and 20000mAh, are listing observations, not published specification sheets, and they should not be read as promised running times for a named model. The honest way to estimate running time is to state the devices, their power draw, and the required bridge time in the inquiry, and let the supplier confirm what fits.

Battery backup for computers is a related but distinct use. A desktop computer draws far more power than a router, so a mini UPS built for network devices is not a substitute for a computer UPS, and this site does not present it as one. The computer backup page explains the boundary: small network and security devices on one side, computers and larger office equipment on the other, with different products for each. Buyers who need both should describe both loads in the inquiry rather than assuming one product covers everything.

For quantity buyers, the same inquiry route applies as for the rest of the range. Minimum order quantity is confirmed per order, customisation can be discussed, certificates are available upon request, and delivery time is not published on this site. The contact page carries the inquiry form and the company contact, Ms. Zita Huang. No telephone number, email address, or street address is published pending verification.
