Floor scrubber and cleaning machine batteries

Electric floor scrubbers and sweepers run brushes and a vacuum motor that draw heavy current for hours. The battery decides how many square metres you clean per charge and whether you finish the shift without swapping machines.

Here you will find 12 V blocks from 90 to 120 Ah and 6 V units in AGM, GEL and flooded lead-acid for walk-behind and ride-on scrubbers.

Machine voltage and layout

Small scrubbers run at 24 V on two 12 V blocks; medium and large machines move to 24 or 36 V with four or six 6 V blocks, which pack more capacity into the same battery compartment. Before ordering, note how many batteries your machine takes, their voltage, their dimensions and whether the terminals are threaded or post type. With 6 V blocks the system voltage only comes from the series connection, so follow the original polarity sequence carefully when fitting them.

Sealed or flooded

Supermarkets, hospitals and offices prefer AGM or GEL: no gassing in normal use, no water to add and no risk of spills on a freshly cleaned floor. Flooded traction batteries last more cycles and put up with rough treatment better, but they need a ventilated charging area and regular level checks. If you switch from one technology to another, change the on-board charger curve; many machines have a selector or DIP switch for it.

Estimating runtime

Multiply the bank voltage by the C5 capacity and allow for 80 % usable energy. Two 12 V batteries at 105 Ah C5 give about 2,500 Wh; if the machine draws 1,000 W, that is roughly two hours of work. Stick to the C5 rating: under a scrubber's load, the C20 figure promises more than you will get.

You will find deep cycle blocks from FULBAT and Q-BATTERY, among others. More formats are listed under traction batteries and among the 6 V and 8 V golf batteries, which some scrubbers also use.

FAQ

Can I fit AGM where flooded batteries used to be?

Yes, if the dimensions fit and the charger is set to the AGM curve. On the flooded profile you would overcharge them.

Should I charge after every use even if there is charge left?

Yes. Leaving the battery half charged until the next day encourages sulphation and gradually reduces runtime.
