Start with cabinet depth
Confirm length, height, terminal clearance and removal path; all models are narrow, but not the same length or height.
NPF Series · 12V 55–155Ah
Tall, narrow front-terminal VRLA batteries designed for service access in telecom and network cabinets, with six catalogue capacities from 55Ah to 155Ah.

Product range
NPF Series places terminals at the front of a narrow 106–109mm case for rack and cabinet access. The catalogue lists 12V 55Ah, 80Ah, 100Ah, 120Ah, 125Ah and 155Ah models, an eight-year design-life statement, flame-retardant case availability and UL reference MH28022. Capacity still varies with discharge rate, so autonomy must be calculated from the required outage duration.
Model comparison
These figures come from the manufacturer catalogue. Ask for the current datasheet before final approval or purchase.

How to choose
Send the information you already have. We can narrow the model list and point out what still needs to be checked.
Confirm length, height, terminal clearance and removal path; all models are narrow, but not the same length or height.
A 100Ah model provides a catalogue-listed 60Ah at the one-hour rate, not 100Ah.
Define series count, string redundancy, breaker or fuse arrangement, cable access and replacement procedure.
Typical applications
Tell us about the equipment and duty cycle. We will help check whether this series is a practical fit.
Review DC bus, outage duration, rectifier settings, cabinet temperature and remote alarms.
Confirm front access, footprint, discharge current and maintenance window.
Account for temperature, service intervals, recharge availability and transport access.
What you can ask for
Commercial terms vary by model, quantity and destination. Include these questions in your inquiry and we will reply with the current available information.

Product FAQ
We will confirm current availability, documents and commercial terms for the exact model you select.
It keeps terminal and connection access at the cabinet front, reducing the need to reach behind a deep battery block.
NP80-12-F and NP100-12-F share the listed 394 × 109 × 286mm size; NP125-12-F and NP155-12-F share 551 × 109 × 288mm.
Use the one-hour capacity column and the actual end voltage, then include aging, temperature and design margin.
The catalogue says a flame-retardant case can be made. Confirm the exact case material and document for the ordered model.
They can suit other narrow-rack standby applications, but voltage, charge profile, runtime and installation must be qualified.
Product inquiry
Send the application, voltage, load, runtime, installation space, quantity and destination you know. We will help turn it into a quote-ready request.
