C&D UPS12-545PLP Pure Lead Plus Battery
C&D UPS12-545PLP Pure Lead Plus Battery
C&D Dynasty UPS12-545PLP Battery - 12V 146 Ah Pure Lead Plus AGM
Warranty
Charge and Discharge Limits
- Float charge voltage 13.65 ± 0.15 VDC - C&D's average per 12V unit, the setting a rectifier holds between events.
- Equalize and cycle service 14.40 to 14.80 VDC - average per 12V unit at +77°F (+25°C), and a distinct setting from float, not simply a higher float.
- AC ripple limits - C&D recommends 0.5 percent RMS or 1.5 percent peak to peak of float voltage, and caps the allowed maximum at 1.4 percent RMS with ripple current at C divided by 20.
- Second current table at 1.80 VPC - 90.7 amps for one hour, 24.8 for five, 16.5 for eight and 7.1 for twenty, for plants that alarm at a higher end point.
- 107 lbs (48.5 kg) - C&D's published weight, which sets the freight class and the lift plan before the rack goes in.

Where This Battery Is Used
- Large UPS rooms - forty-block strings behind a rectifier plant that was engineered to the load.
- Power generation plant UPS - control room and distributed control system power on a maintained charge.
- Manufacturing with sequenced shutdown - lines that have to be brought down in order instead of dropped all at once.

Frequently Asked Questions
How should a rectifier be set up for a UPS12-545PLP string?
Three numbers govern it. Float sits at 13.65 volts per block, so a forty-block string floats at 546 volts and a twenty-four block string at 327.6. Charge current is limited to 29.2 amps per block, which is the figure to check against the rectifier's current-limit setting, a different number from its rating plate. Ripple stays inside 1.4 percent RMS of float voltage with ripple current no higher than C divided by 20, and both are worth measuring at commissioning instead of assuming from the power supply's datasheet.
What does the 800 amp maximum discharge current mean in practice?
It is the ceiling C&D prints in the additional-data column headed maximum discharge current, and it sits well above anything a UPS ride-through draws. Where it matters is an inverter fault or a badly configured load step, when the string can be asked for far more than the sizing table assumed. The 5,000 amp short-circuit figure is a different quantity again, measured at 0.1 second into a bolted fault, and the DC breaker interrupting rating is compared against it.
Can a UPS12-545PLP be used in cycling service?
C&D publishes an equalize and cycle service charge voltage of 14.40 to 14.80 VDC for the series, so the charging side of cycling duty is defined. The Pure Lead Plus range is specified for standby UPS work, and a battery cycled daily lives a different life from one that floats for years and discharges twice. If the application cycles, send the depth of discharge and how often, and a specialist sizes it against C&D's cycling data instead of the standby figures on this page.
How much current will a UPS12-545PLP supply for three hours?
40.4 amps to 1.75 volts per cell at 77°F, or 38.2 amps to a 1.80 end point. At five hours the figure is 26.0 amps and at one hour it is 99.8. Those rows suit a plant load that runs steadily. A UPS discharge is read off the watts-per-cell table.
