12NXS120 TPPL Battery

12NXS120: The Versatile Mid-Range NexSys® TPPL Battery

Flooded lead-acid batteries cost more than their purchase price suggests. Watering schedules, acid spills, corrosion repairs, and mandatory cooldown periods add up to hours of lost productivity every week. The 12NXS120 NexSys® TPPL battery eliminates all of it.

Built on EnerSys Thin Plate Pure Lead (TPPL) technology, the NexSys 12NXS120 delivers 120Ah of capacity at a 12V nominal voltage-enough to power a full shift in most walk-behind and compact ride-on scrubbers. It is sealed, maintenance-free, and charges in under two hours. No watering. No acid checks. No downtime waiting on a charge cycle.

Which Machines Does the 12NXS120 Fit?

The 12NXS120 battery is engineered for mid-size cleaning equipment. At 13.31 x 6.81 x 10.71 inches, it fits standard battery compartments designed for Group 31 or GC12 type flooded batteries-no modifications required.

Compatible Equipment

• Tennant T300, T300E, T&, and T7AMR
• Advance SC500 and SC2000
• Clarke Focus II 20”, RA40, and CA60
• Other small to mid-size scrubbers using Group 31 or GC12 battery configurations

Why Choose the NexSys® 12NXS120?

The 12NXS120 sits in the sweet spot of the NexSys® range: enough capacity for full-shift operation in walk-behind scrubbers, compact enough for standard battery compartments. It is the versatile mid-range option for commercial cleaning fleets that need reliability without oversizing.

Key Advantages

• Full-shift runtime. 120Ah delivers consistent, all-shift power in most walk-behind applications.
• Maintenance-free operation. TPPL technology means zero watering, zero acid checks, and zero corrosion cleanup. Install it and move on.
• Fast charging in under two hours. Plug in during breaks or between shifts. The 12NXS120 accepts high-rate and opportunity charging, cutting downtime dramatically compared to the 8+ hour cycles flooded batteries demand.
• 1,500+ cycle life. TPPL chemistry delivers significantly more cycles than conventional flooded batteries, reducing replacement frequency and lowering total cost of ownership.
• Direct drop-in replacement. Engineered to replace Group 31 and GC12 flooded batteries without machine modifications.

Charging the 12NXS120: Fast and Flexible

Flooded batteries lock you into rigid charge cycles-8 hours to charge, plus a cooldown period before the battery is ready. The NexSys® 12NXS120 supports both fast charging and opportunity charging. A full charge completes in under two hours. A 15-minute plug-in during a break adds meaningful runtime. Over a typical shift cycle, opportunity charging can keep your scrubber running all day without a dedicated charging window.

Recommended Charger

For optimal performance and maximum cycle life, pair the 12NXS120 with a NexSys®-compatible on-board charger, for increased convenience, or off-board charger, for faster charging. These chargers deliver the precise charging profile that Thin Plate Pure Lead technology requires, protecting the battery and maximizing lifespan.

12NXS120 vs. Flooded Batteries

Replacing a flooded lead-acid battery with the NexSys® 12NXS120 changes daily operations:

• No watering. The 12NXS120 is sealed and maintenance-free-no scheduled water top-offs.
• No acid spills. Sealed construction eliminates electrolyte leaks, equipment corrosion, and the safety risks of open-cell batteries.
• Faster recharge. From 8+ hours down to under two hours with a TPPL-compatible charger.
• Stable voltage throughout discharge. Your scrubber delivers the same cleaning performance at the end of the shift as it does at the start.
• Longer service life. Up to 1,500+ cycles versus the 500–800 cycles typical of flooded batteries. Fewer replacements, lower lifetime cost.

Frequently Asked Questions

Which floor scrubbers does the 12NXS120 fit?

The 12NXS120 is compatible with Tennant T300, T300E, T7, and T7AMR; Advance SC500 and SC2000; Clarke Focus II 20”, RA40, and CA60 and other small to mid-size scrubbers using Group 31 or GC12 battery configurations.

What voltage system does the 12NXS120 work with?

The 12NXS120 is a 12-volt battery. Many mid-size scrubbers run on 24V or 36V systems, requiring two or three 12NXS120 batteries wired in series. Check your equipment specifications for the required system voltage.

How does 12NXS120 runtime compare to a flooded battery?

At 120Ah, the 12NXS120 delivers comparable or better runtime than a same-size flooded battery, with more consistent power output throughout discharge. The ability to opportunity charge during breaks extends effective daily runtime well beyond what a single flooded-battery charge cycle provides.

What charger do I need for the 12NXS120?

For optimal performance and maximum cycle life, pair the 12NXS120 with a NexSys®-compatible on-board charger, for increased convenience, or off-board charger, for faster charging. These chargers deliver the precise charging profile that Thin Plate Pure Lead technology requires, protecting the battery and maximizing lifespan.

Is the 12NXS120 a direct replacement for my current flooded battery?

In most cases, yes. The 12NXS120 is designed to fit standard compartments for Group 31 and GC12 type flooded batteries. Physical dimensions and terminal configuration support drop-in replacement. Confirm your compartment dimensions and terminal layout before purchasing.
