If you're sourcing replacement batteries for an existing floor scrubber fleet, or specifying batteries for new equipment procurement, the lithium vs AGM decision comes down to total cost of ownership over your equipment lifecycle.
AGM batteries: 400-550 cycle life. Polinovel LiFePO4 floor scrubber batteries: 4,000+ cycles, UN38.3 certified, 5-year warranty.
We manufacture lithium batteries for Tennant, Nilfisk, Karcher, Hako, Comac, FIMAP, Viper, PowerBoss and other major cleaning equipment platforms.
Floor Scrubber Battery Cost Comparison
AGM batteries for commercial floor scrubbers cost $600-$1,500. Polinovel lithium packs run $1,500-$3,000 depending on voltage and capacity.
In daily commercial use-warehouses, airports, retail distribution centers-AGM batteries typically last 18 to 24 months before capacity drops to unacceptable levels. Multi-shift operations see faster degradation. A Polinovel battery installed at the same time will still run at rated capacity when that AGM gets swapped out for the second or third time.
The maintenance cost gap widens this further. AGM requires 6-8 hour charging sessions that cannot be interrupted. Partial charging-plugging in during lunch break, unplugging when the shift starts-damages AGM cell chemistry permanently. Capacity loss accumulates with each interrupted cycle. Within months, a battery rated for 4-hour runtime delivers 2.5 hours. Operators compensate by running additional machines or extending shift times. Neither option is free.
Lithium handles this differently. Polinovel LiFePO4 batteries support opportunity charging without degradation. Plug in for 30 minutes during break. Unplug when needed. No capacity penalty. The BMS manages cell balancing automatically. This operational flexibility is why distribution centers running 16-hour or 24-hour operations increasingly specify lithium for new equipment purchases-AGM cannot support their charging windows.
Charging time itself affects labor scheduling. AGM needs 6-8 hours for full charge. Polinovel lithium packs reach 80% in under 2 hours, full charge in 2-3 hours depending on charger output. For facilities that cannot dedicate overnight charging windows to each machine, this difference determines whether equipment is available when shifts start.
Polinovel Floor Scrubber Battery Specifications
Our industrial floor cleaning machine batteries use lithium iron phosphate cells-same LiFePO4 chemistry Tennant specifies for their T12 and T16 lithium-ion scrubbers.
Thermal stability advantage over NMC and other lithium chemistries: LiFePO4 passes needle penetration tests without fire or explosion. Polinovel battery packs pass the full safety testing suite-needle penetration, overcharge, short circuit, crush, thermal shock. For 24/7 warehouse environments with unattended charging, thermal stability is not a feature preference. It is a facility safety requirement.
Every Polinovel battery pack integrates BMS with RS485, RS232, CAN communication protocols. This enables direct integration with equipment controllers on compatible machines-battery status, state of charge, cell voltages, temperature data available to the machine's onboard diagnostics. For operations upgrading from AGM, the BMS also monitors charging parameters. If a lead-acid charger exceeds lithium voltage requirements, the BMS intervenes before cell damage occurs. This matters because charger compatibility is the most common technical issue in AGM-to-lithium conversions.
Standard voltage configurations: 24V, 36V, 48V. Capacity range from 80Ah to 315Ah covers walk-behind scrubbers through large ride-on machines. Weight runs 50-60% lighter than equivalent AGM capacity-relevant for facilities using removable battery systems with manual swap protocols.
Custom dimensions engineered for drop-in replacement on specific machine models. Polinovel maintains CAD files for common OEM battery compartments. Send your equipment model numbers; we confirm whether standard packs fit or custom engineering is required.
AGM to Lithium Conversion: Charger Compatibility
This is where most conversion projects stall. Lithium batteries require charger voltage parameters matching LiFePO4 chemistry-bulk voltage, absorption voltage, float voltage all within specific ranges. Exceed those parameters and the BMS will refuse to charge, or worse, cells degrade.
Some existing lead-acid chargers qualify. The charging profile labeled "GEL" on many industrial chargers comes closest to LiFePO4 requirements. But close is not the same as compatible. Verification is required for each charger model.
Polinovel provides compatibility assessment as part of the quoting process. Send equipment model numbers and existing charger specifications-manufacturer, model, output voltage, charging profile. We return confirmation of direct compatibility or identify required charger upgrades with specific model recommendations.
For Tennant T-series (T7, T12, T16, T17), Nilfisk SC-series, Karcher B-series, and comparable OEM platforms, we maintain dimensional specifications for drop-in replacement without equipment modification. Battery compartment dimensions, terminal positions, connector types documented. Technical documentation downloads available on product pages-no sales conversation required to access specs.
What about machines with proprietary battery management? Some OEM equipment communicates with batteries through proprietary protocols. Tennant's newer lithium machines, for example, expect specific handshake sequences. Polinovel can engineer BMS firmware to match these protocols for volume orders. Minimum order quantities apply. For single-machine replacements on proprietary platforms, OEM batteries may be the only practical option-we will tell you this upfront rather than ship incompatible product.
Polinovel Warranty and Support Structure
5-year warranty based on accelerated aging test data. Polinovel batteries pass charge/discharge cycling, vibration, salt spray, high temperature (+60°C), low temperature (-20°C) testing protocols. Warranty terms specify performance thresholds: capacity below 70% of rated within warranty period qualifies for replacement.
Regional distribution and technical support in North America, Europe, Australia. Warranty claims process through regional contacts-you are not shipping batteries to Shenzhen. Response time commitments written into purchase agreements for volume customers.
Advance replacement available on qualifying contracts. Replacement battery ships before failed unit returns. This eliminates equipment downtime waiting for warranty processing. Specifics depend on order volume, geography, and agreement terms-discuss during quoting.
For facilities where floor scrubber downtime creates immediate operational impact, this support structure matters as much as battery specifications. A 5-year warranty means nothing if exercising that warranty takes your equipment offline for weeks.
Polinovel LiFePO4 Battery OEM and Distribution Partnerships
Polinovel does not sell direct to end users for single-unit purchases. Our channel is distributors, equipment dealers, and OEM accounts.
For equipment dealers adding lithium battery options to existing floor care lines: private label programs available. Your branding on battery enclosures, your part numbers in documentation, Polinovel manufacturing and warranty backing. Minimum order quantities apply.
For facility management companies standardizing battery specifications across multi-site operations: volume pricing tiers and blanket purchase agreements available. Consolidate your floor scrubber battery procurement across sites with single supplier pricing.
For OEM equipment manufacturers seeking lithium battery supply: engineering support for custom form factors, BMS protocol matching, integration testing. We supply batteries to equipment manufacturers who then sell complete machines under their own brands.

Include: machine manufacturer and model numbers, quantity, current charger manufacturer and model if evaluating conversion, shipping destination. The more complete your initial inquiry, the faster we return actionable quote with landed cost.
24-48 hour response for standard configurations. Faster for existing OEM partners and repeat distribution customers.
Procurement managers building budget projections: request the ROI calculator spreadsheet. Input your facility's labor rates, current battery replacement frequency, charging infrastructure details. The calculator returns break-even timeline specific to your operation-single-shift facilities see different payback than multi-shift warehouses, and generic industry averages miss variables that matter for your capital expenditure approval.
For urgent replacement needs: Polinovel maintains inventory of common configurations at regional distribution points. Stock availability varies-confirm during inquiry if timeline is critical to your decision.
