Floor Scrubber Batteries and Charging
Batteries are the most expensive wear part on a cordless floor scrubber, and how they are charged and maintained decides whether a set lasts two years or five. Most battery failures in scrubber fleets are not defects. They come from a charger set to the wrong profile, flooded cells left low on water, packs stored discharged, or short partial charges on batteries that need a full cycle every day.
This section is written for the people who run, maintain and buy machines. Start with floor scrubber batteries for the basics of chemistries, voltages and runtime. Then battery chargers explains onboard and offboard units and why flooded, AGM, gel and lithium need different charge profiles. For flooded lead-acid sets, see watering flooded batteries, equalizing charges and the routine in battery maintenance.
When a set is worn out, the battery replacement guide covers voltage matching, amp-hour ratings and core return. If you are weighing lithium, read lithium conversion and opportunity charging for the cost and shift math. And if a machine will not take a charge, battery not charging walks through the checks in order. Figures are typical ranges, so confirm against your battery and charger manuals.

Floor Scrubber Battery Chargers: Onboard vs Offboard and Choosing the Right Charge Profile
Onboard vs offboard floor scrubber chargers, how charge profiles differ for flooded, AGM, gel and lithium batteries, and why a wrong profile kills batteries.
How to Water Flooded Floor Scrubber Batteries (When, How Much, and With What)
When and how to water flooded scrubber batteries: distilled water, correct fill levels, how often to check, and how single-point watering systems work.
Equalizing Charges for Floor Scrubber Batteries: When, Why and How
What an equalizing charge does, when flooded scrubber batteries need one, how to run it safely, and why AGM, gel and lithium should never be equalized.
Opportunity Charging Floor Scrubbers: When It Works and When It Ruins Batteries
Opportunity charging floor scrubbers during breaks: why it suits lithium, why it hurts lead-acid, and a shift model to check if your charger can keep up.
Floor Scrubber Battery Not Charging: Step by Step Troubleshooting
Scrubber batteries not charging? Check the outlet, plug, charger interlock, fault lights, deeply discharged batteries and lithium BMS lockout, in that order.
Floor Scrubber Battery Replacement Guide: Matching, Fit, Wiring and Disposal
Replacing floor scrubber batteries: match voltage, compare Ah at the 20 hr rate, check fit, wire 6V, 8V or 12V units for 24V and 36V, and return cores.
