Frequently Asked Questions
How much load can one HR1234W carry through a 15-minute outage?
CSB's constant-power table puts it at 206 watts per battery over 15 minutes to 1.67 volts per cell at 77°F. Lighter loads stretch the time: the same battery holds 119 watts for 30 minutes and 68.9 watts for a full hour. For a string, multiply by the battery count, then size against the inverter's real draw rather than its nameplate. Send the load and the window and we run the numbers from CSB's own table.
Is HR1234W F2 a different battery from HR1234W?
Same battery, one detail specified: F2 names the 0.250-inch Faston terminal tab. Buyers type the string printed on the label, which reads HR 1234W F2, and this listing is that build. If the connectors in your tray are the narrower 0.187-inch type, say so on the quote so the terminal question is settled before anything ships.
Can a general purpose battery of the same size do this job?
It fits the tray, and in a UPS it gives up real runtime. A general purpose design of this footprint is rated for long, slow discharges, and its delivery falls off steeply at 15-minute rates. The HR plate set is arranged for exactly that window. The honest flip side: on float duty with rare, slow discharges, an alarm panel or emergency lighting circuit, the general purpose unit does the job for less money, and we will say so if that is your application.
