Frequently asked questions

What does FR mean on this battery?

It marks the flame retardant version. The case is ABS rated UL94 V0.

What float voltage should the charger use?

13.65 V per 12 V block (±1%) at 20°C, which is 2.275 V per cell.

Can it be fitted on its side?

Yes. It can be installed in any orientation except permanently inverted.

How long will it last?

Yuasa gives a design life of up to 10 years at 20°C, and it is in the EUROBAT long life class of 10 to 12 years.

Can it go in a sealed box?

No. VRLA batteries release hydrogen gas which can form explosive mixtures, so never place it inside a sealed container.

Yuasa NPL100-12FR 12V 100Ah Industrial VRLA Battery, Flame Retardant Case, M10 Terminals

Overview

This is a large 12 V block from Yuasa's NPL industrial range, in the flame retardant version.

The full Yuasa battery range covers smaller blocks for alarms and emergency lighting.

How it works

VRLA stands for valve regulated lead acid. Each cell has a low pressure release valve that lets gas escape and then reseals.

On standby, the charger holds the battery at its float voltage; a higher cyclic or boost voltage is used where it is charged and discharged often.

Where to use it

In most installations, a block of this size is chosen for long standby times, for example in an uninterruptible power supply. Always check the equipment maker's battery requirements first.

The UL94 V0 case suits sites where the fire behaviour of the battery case matters.

Store it fully charged between -20°C and +50°C. It can be charged from -15°C to +50°C and discharged from -20°C to +60°C.

What the figures mean in practice

  • 100 Ah at 20 hours: the capacity over a 20-hour discharge to 1.75 V per cell; heavier loads give less.
  • 4 mΩ impedance: low internal resistance, which is why it can deliver 1000 A for a second.
  • No float current limit: on float the charger does not need to limit current; on cyclic charge, keep it to 25 A.

Installing it

At 39 kg, lift it from below and never by the handles alone.

Leave the enclosure ventilated, because VRLA batteries release hydrogen gas. As a rule, check terminal tightness and voltage with a lead acid battery tester at each service.

Planning your system

Size the battery from the load and the standby time needed, then check the charger float voltage matches 13.65 V per block. Other sealed lead-acid batteries cover smaller loads, and uninterruptible power supplies have their own range.

When it is finally replaced, it must be recycled in line with local and national law. The wider batteries and power supplies range covers chargers and accessories.

Standards and ratings explained

UL94 V0 is a plastics flammability rating where burning stops quickly on a vertical test piece, the strictest of the common V ratings. EUROBAT is the European battery makers' body, and its long life class describes expected service life.
