You rely on your floor care equipment to keep your production running smoothly. Crown Battery’s floor scrubber batteries provide continuous power for your equipment needs so you can have peace of mind. Smart customers choose Crown because they know we offer a world-class array of batteries tailor-made to fit all their requirements. Plus, Crown’s quality is understood, with thicker plates and thicker grids that make our batteries work and last 
longer. From small machines to highly complex industrial equipment, we understand all deep cycle applications. So, with Crown, you’re not only getting the world’s finest batteries, but experience that powers your every need.
Floor scrubbers are very hard on batteries, so our customers need every advantage they can get when it comes to powering their equipment. With a true deep cycle battery from Crown Battery, you’re getting the best in the industry! With a large assortment of sizes, A/H ratings and Reserve Capacities, we can find the battery that fits your needs.
Which Battery is Right for You? Flooded or AGM?
There’s really no need to worry – Crown has floor scrubber batteries for both needs – flooded and AGM. Both types of batteries will give you long and substantial power for all your floor care needs. Both batteries have a 
thick plate, thick grid. They will provide the run time and the longevity you expect. With more and more facilities requiring the use of AGM batteries in their floor care equipment, you can be sure Crown has the batteries you need. You can find additional information on AGM deep cycle batteries along with specifications in the AGM Deep Cycle area of the website.
Proper Charging of Floor Scrubber Batteries – Guidelines, Battery Life and Performance
Deep cycle batteries provide all the power used in floor care equipment. You measure battery life in cycles. One full cycle represents a battery discharge (use of equipment), a full recharge (charging of battery) and finally a cool down of battery (rest period where battery is charged in float mode). Several factors affect battery performance and battery life:
- Using proper battery for the equipment.
- Depth of discharge of the battery (DoD). The lower you discharge the batteries, the less number of cycles the battery will provide.
- Recharge the batteries to a full state of charge immediately following the discharge cycle.
- Keep terminals and cables in good condition.
Charging Techniques
The battery charger is an important part of maintaining good battery service and extended life. Since floor care equipment is very hard on floor scrubber batteries, routinely discharging them to 80% DoD, it is important to fully charge the batteries and let them rest before putting them back into service. You can accomplish this by using the proper charger and allowing enough time between uses. We recommend 15 amps of charging output per 100 A/H of battery capacity. For example:
(2) 31DC130 in a scrubber @ 24 volts. You have 130 A/H of battery power. 130/100 = 1.3 X 15 amps = 19.5 amps.
So, for this equipment, you should use a charger that can provide at least 20 amps of charging output. Many of these machines come with a 12 or 15 amp charger. So, if you don’t have enough time to fully charge your battery bank, your bank won’t last as long as it should. Equalization charges are important in floor care equipment. Equalize your battery bank at least once a month. More often if you typically discharge your bank to 80% DoD. Some chargers automatically go into equalization mode and some have to be manually put into that mode.
Battery Watering
Battery watering is very important. Under-watering will leave the plates exposed and they will eventually dry out. When a plate dries out, it loses capacity. Over-watering dilutes the sulfuric acid which results in poor performance. It could also cause the battery to overflow during use or recharge. Periodic inspection of fluid levels will allow you to build a watering schedule. Add water, if needed, after the charge cycle is complete. If the plates are exposed, add water before the charge cycle. After charging, the fluid level should be between the top of the plate and the bottom of the filler tube.
