C&D UPS12-355PLP Pure Lead Plus Battery
C&D UPS12-355PLP Pure Lead Plus Battery
C&D Dynasty UPS12-355PLP Battery - 12V 94 Ah Pure Lead Plus AGM
Warranty
Power Below Five Minutes
- Specified for sub-five-minute duty - C&D designs the Pure Lead Plus series to handle runtimes under five minutes safely without trading away long-term performance.
- Patented long-life grid alloy - C&D's alloy is specified to hold grid growth and gassing down across the float service life.
- 4,200 amps short-circuit current - at 0.1 second, the figure the DC breaker and fuse coordination on this string gets checked against.
- UL 94 V-2 and UL 94 V-0 materials - the flammability ratings C&D lists for the series, alongside UL 1973 for stationary energy storage.
- Threaded inserts on the cover face - taking a 1/4-20 UNC bolt at 110 in-lbs (12.4 N-m), set with a torque wrench, never by feel.

Frequently Asked Questions
How much power does a UPS12-355PLP hold for one minute?
1,045.0 watts per cell to 1.67 volts per cell at 77°F, which is 6,270 watts from one block. To a 1.70 end point the figure is 1,005.9, and to 1.60 it rises to 1,153.7. A forty-block 480 VDC string therefore carries roughly 251 kW for that first minute at the 1.67 end point. Two minutes brings it down to 905.0 watts per cell, three to 811.2 and four to 728.3.
Does a short discharge wear this battery faster?
C&D specifies the Pure Lead Plus construction for safe handling of runtimes under five minutes without sacrificing long-term performance, which is why the series publishes rates down to one minute in the first place. Where the block you are comparing against does not publish below five minutes, there is no published figure to size that duty against. Send the discharge profile with your quote request and a specialist checks it against the published table.
What does the UPS12-355PLP do on a long, low-current discharge?
16.8 amps for five hours, 11.0 amps for eight, 9.0 amps for ten, 4.7 amps for twenty and 4.0 amps for twenty-four, all to 1.75 volts per cell at 77°F. Those are the rows to use for a telemetry cabinet or a control load that draws steadily rather than in a burst. C&D also publishes a 1.80 VPC current table if your plant alarms at a higher end point.
Is the UPS12-355PLP the same case as the UPS12-405PLP?
No. They share the 173 mm width, but the 405PLP is 341 mm long against 306 and 216 mm over the terminals against 205, and it weighs 76 lbs against 67. A tray cut for the 355PLP will not take the 405PLP without gaining 35 mm of length and 11 mm of height. Going the other way, a 405PLP shelf holds a 355PLP with room to spare, though the restraint bar will need repositioning.
