C&D UPS12-405PLP Pure Lead Plus Battery
C&D UPS12-405PLP Pure Lead Plus Battery
C&D Dynasty UPS12-405PLP Battery - 12V 104 Ah Pure Lead Plus AGM
Warranty
Same Shelf as the Retired 400MR
- Pure lead construction - C&D's pure lead technology in an AGM VRLA block, with the patented long-life alloy carried in the grids.
- BS6290-4 and IEC60896-22 - the British and IEC stationary VRLA references C&D lists for the series, useful when a specification was written to a European standard.
- 4,700 amps short-circuit current - at 0.1 second, up from 3,600 on the 305PLP and 4,200 on the 355PLP as the plate area grows.
- No electrolyte maintenance - a valve regulated recombinant block takes no water across its service life, which is what keeps a sealed cabinet workable.
- Nominal operating window +74°F to +80°F - C&D's stated room band (+23°C to +27°C) for the series, and the ambient a battery room should be held at.

Where This Battery Is Used
- MR-era UPS trays - shelves cut for the 400MR class, reused without mechanical rework.
- Colocation suites - cage-level strings where the rack footprint is fixed by the lease and cannot grow.
- Water and wastewater SCADA - control and telemetry power at treatment plants and lift stations.

Frequently Asked Questions
Will a UPS12-405PLP drop into a tray built for the UPS12-400MR?
Mechanically it should. C&D publishes 341 by 173 mm for the 405PLP and 340.9 by 172.7 for the 400MR, a difference of tenths of a millimeter, with total height of 216 against 216.4. Both take a 1/4-20 UNC bolt in a threaded insert. Measure the tray anyway, because rack hardware from different years carries its own tolerances, and send a photograph of the terminal layout with your quote request if the string is more than a few years old.
Does the 405PLP weigh enough more to matter for the shelf?
76 lbs against 75.8 on the MR, so two tenths of a pound per block. A forty-block string gains eight pounds in total. Shelf ratings and seismic calculations built around the older cabinet carry over; the number worth rechecking is the floor loading only if the room was close to its limit before.
What does the UPS12-405PLP hold at the five-minute column?
710.0 watts per cell to 1.67 volts per cell at 77°F, or 624.0 to 1.75, which is 4,260 and 3,744 watts from one block. At one minute the figure is 1,158.5 watts per cell. Those three columns cover most generator-start profiles, and the full table runs out to 140.2 watts per cell at sixty minutes.
How many amps will a UPS12-405PLP supply over eight hours?
11.9 amps to 1.75 volts per cell at 77°F, which is the 95 Ah C8 rating. Over twenty hours the figure is 5.2 amps for 104 Ah, and over five hours it is 17.9 amps. A 48V plant of four blocks drawing a steady 12 amps therefore sits right at the eight-hour mark before the string reaches its end point.
