Lithium-Ion Batteries: Four Benefits

June 21, 2018 8:30 AM by Tennant Company



Why Lithium-Ion Batteries?


The big buzz in batteries is lithium-ion technology. So’s the premium price. What are you buying when you choose this option, and what are the benefits?

Rechargeable lithium-ion (Li-on) batteries are increasingly popular as a power option for small- to mid-sized cleaning equipment. Their advantages fall into four broad categories: maintenance, longevity, charging speed, and ease of charging. See if these benefits make sense for your facilities.


Four Benefits


Maintenance – unlike flooded lead-acid batteries with water levels that need to be monitored, Li-on batteries do not need to be watered. This reduces the maintenance needed to keep the batteries operational, which also eliminates training new team members on the procedure and monitoring machines to ensure that water levels are correct.

Longevity – with a typical life expectancy of as long as six years for a large-capacity battery pack, the investment you make up front in the option provides a return in its long service life.

Charging speed – Li-on batteries charge faster than their counterparts, meaning less downtime for the machine while it’s tethered to a charging station. In a busy facility, of course, the less time a machine has to sit idle, the better.

Ease of charging – Also reducing downtime for a machine, the Li-on battery can be opportunity charged. This means that cleaning procedures don’t have to be designed around the need to allow a battery to fully charge in between uses, and also simplifies training for team members.

Time savings, simplified training, and long battery life are some of the biggest reasons that more facilities are making the investment in Li-on batteries. Would these benefits be useful in your operations?
