C&D Technologies UPS12-210MR Battery
C&D Technologies UPS12-210MR Battery
C&D Dynasty UPS12-210MR Battery - 12V 53.8 Ah High Rate Max AGM
Warranty
The Step Before the Quarter-Inch Terminal
- Patented Long Life Alloy - C&D's low-calcium grid alloy, which the sheet credits with minimizing grid growth, reducing gassing and extending battery life.
- Bellcore 4228 recombination behavior - C&D designs the MR case around the same recombination, thermal-runaway prevention, gassing and flame-retardant characteristics as its 4228-compliant Dynasty Telecom blocks.
- Flame retardant polypropylene to UL94-V2 - case and cover both, on a UL-recognized component that also meets UL1778, UL 924 and UL 1989.
- Impedance 0.0045 ohms at 60 Hz - C&D prints this for reference and says plainly that individual baselines are the ones to diagnose against.
- Air transport cleared - not restricted under IATA and ICAO Special Provisions A67, and non-hazardous per IMDG Amendment 27 by water.

Where This Battery Is Used
- Internet housing sites - colocation suites where the string carries the cage to generator transfer.
- Semiconductor manufacturing - tool power on lines where a dropped wafer lot is the real cost of an outage.
- Hospital and laboratory backup - code-driven standby power that gets inspected and load-tested on a schedule.

Frequently Asked Questions
What constant power does the UPS12-210MR hold for 45 minutes?
90.3 watts per cell to 1.75 volts per cell, or 92.6 to 1.67 VPC, at 77°F. Multiply by six cells for the block and by the string count for the plant figure: twenty blocks at the 1.75 end point give roughly 10.8 kW for three quarters of an hour. C&D publishes 5, 10, 15, 20, 30, 40, 45, 50, 60 and 90 minute columns for this model at five end-point voltages.
Which C&D manual covers installing a UPS12-210MR rack?
Technical manual 41-7525, the rack-mounted installation and start-up guide for 12V VRLA batteries of 26 to 206 ampere-hour capacity. The 210MR's 53.8 Ah sits well inside that band. The guide covers battery numbering, interunit and intertier cabling, the pre-operational checks and the initial freshening charge, and it points to Form 41-7471 for the operational qualification checklist.
How much space goes between blocks on the shelf?
Half an inch (1.27 cm) between units, per C&D's installation guide. The gap does two jobs: it lines the interunit cables up with the adjacent terminals, and it lets convection carry heat away from the cases. Place all the blocks on a tier with the same polarity to the front, and load the lowest tiers first for rack stability.
What impedance reading should a new UPS12-210MR show?
C&D publishes 0.0045 ohms at 60 Hz for this model and marks the figure for reference only, recommending individual baselines for diagnostic work. Take your own readings at installation, log them per battery number, and trend the drift rather than the absolute value. C&D's technical bulletin 41-7271 covers impedance and conductance testing method.
