Where This Battery Is Used
- Growing UPS installations - server rooms whose DC bus load has outrun the string that was sized five years ago.
- Hospital and lab power quality systems - loads where the transfer window is non-negotiable.
- Telecom power plants - high-rate bridging in front of the generator at switch sites.
- Modular data-center rows - dense strings where every inch of tray earns its keep.

Frequently Asked Questions
When is the XP12-350FR the right pick over the XP12-300FR?
When the runtime math says so. Both share the 6.61 by 8.19 inch cross-section; the 350 is 1.8 inches longer, 8.8 lbs heavier and carries 50 more watts per cell over the 15-minute window. If your string is riding close to its low-voltage cutoff at today's load, the 350 restores margin without changing the tray height. Send the DC bus load and we will run the numbers both ways.
Can I mix XP12-350FR and XP12-300FR units in one string?
No. A series string discharges through every unit equally, and mismatched models drag the string to the weaker unit's curve while overworking it. Replace a string with one model, one age, one lot where possible. If you are expanding, quote the whole string rather than topping up.
Is 95 Ah the number I should size runtime on?
Not for UPS work. The 95 Ah is a 20-hour figure, and a UPS discharge is 5 to 30 minutes. Size on the 15-minute watts-per-cell rating at your end voltage. The amp-hour figure matters mostly for comparing physical battery classes and for long, low-rate duties this unit is not usually bought for.
Does it need a ventilated cabinet?
It is a sealed VRLA that recombines gas internally in normal service, so it lives in equipment rooms and enclosed cabinets rather than battery rooms. Enclosures still need the modest airflow every VRLA installation calls for, and your AHJ or facility specification governs. Ask the specialist to include the installation guidance with your quote if the enclosure is tight.
