Case Study
Share:
When Gel batteries were introduced into the industry, they were roughly 4 times the cost of a lead acid battery. As higher volumes were produced for the Gel batteries, they rapidly reduced in price and increased in quality.
Today, a gel battery will cost roughly 30% more than that of a wet lead acid battery with none of the headaches, maintenance, or charging issues. As a result, gel batteries are now more commonly used in floor scrubbers and floor sweepers. However, gel batteries are beginning to be phased out and replaced with Lithium. You can learn about some of this exciting technology in our blog One Battery to Run Them All.
A common question asked is what the main differences between these batteries are so to help you out, below highlights the key advantages and disadvantages of Gel and Lead batteries.
