Where This Battery Is Used
- Colocation and hosting halls - mid-size UPS cabinets stepping up from a 300MR string without changing terminal hardware.
- Testing laboratories - instrument and environmental-chamber power on a maintained float charge.
- Industrial process control facilities - controlled shutdown on lines that have to be brought down in sequence.

Frequently Asked Questions
Will a UPS12-350MR drop into a tray cut for the UPS12-300MR?
In width and height, yes. The 350MR is 6.83 inches wide and 8.06 inches over the terminals against the 300MR's 6.83 and 8.01, a five-hundredth of an inch apart. The length is where it changes: 12.04 inches against 10.27, so each block needs 1.77 inches more run on the shelf, and a tier of ten needs nearly eighteen. Measure the tier before the order, not after delivery.
What is the maximum charging current for a UPS12-350MR?
C&D sets the recommended limit at C20 divided by 5 at the 20-hour rate. For this block's 93.2 Ah that is 18.6 amps per unit. A rectifier that can source more than that into a recovering string will run the plates hot, and the excess does nothing for recharge time once the block starts accepting less current on its own.
What ambient does C&D call nominal for this block?
+74°F to +80°F, which is +23°C to +27°C. That is the room band C&D asks for, and it is a separate figure from the rating temperature: the 93.2 Ah and the 350 watts per cell are both taken at 77°F (25°C), and the 10 year design life is quoted at 25°C. A cabinet that runs above that band keeps working, and the ratings on this page stop describing it. Send the average ambient with the quote request and a specialist notes it.
How cold or hot can a UPS12-350MR run?
C&D publishes a discharge range of -40°F to +160°F, which is -40°C to +71°C, and a charge range of -10°F to +140°F, or -23°C to +60°C, with temperature compensation. Operating cool cuts the discharge time available, so a shelter that swings below freezing needs the runtime checked at the low end rather than at 77°F.
