As carbon neutral has become the global mission, many organisations are considering switching to electric forklift. As the core of electric forklift, what type of forklift battery you choose has determinant effects on your Return-on-Investment. This blog would provide guide to forklift battery types, including lead acid, AGM and lithium battery, covered the basics of what makes each type of battery stand out.
Lead Acid Forklift Battery (also called wet cell battery):
Since invented in 1859, Lead Acid battery has been used in the forklift industry for over 100 years. It is currently the most common battery in the forklift market. It includes a battery case, cells, and cables, as well as a mixture of sulfuric acid and water.
If it is taken care by regular maintenance and watering to maintain electrolyte, it potentially allows for 1000 charging cycle and last up to five years on average.
Absorbed Glass Mat Forklift Battery (AGM Battery):
As a sealed Lead Acid battery, AGM battery became popular in 1980s due to its reduced weight and improved reliability. It uses a special glass mat to pass electrolytes between battery plates.
By suspending electrolytes in this dry state, it requires less maintenance and sometimes it is called maintenance-free as it needs no watering. It also negates the risk of spilled battery acid in case of a cracked battery case. However, the charge cycles can harm its life and performance. Research indicated that AGM battery would last longest and perform best only if they discharge up to 50% of capacity per cycle.
Lithium-Ion Forklift Battery (Li-Ion Battery):
Even though Li-Ion battery has been widely used in the phones and other small electronics since the 1980s, it has not been made to the forklift industry until now. With the development of the Li-Ion battery technology, it has reduced the chance of combustion due to overcharge and increased safety. Hence, major forklift brands are making the change from lead-acid to Li-Ion due to its superior performance and reduced costs over its lifetime.
Comparing to lead acid battery, it is maintenance-free and reduces possible risks to workers. Moreover, it has higher energy efficiency and allows for quick charging and opportunity charging which could be cost-prohibitive for some business.
Next week, we will bring you to the history of BYD lithium battery. It would help you figure out why you should switch to BYD lithium battery forklift. Follows us on Facebook and get to know more about electric forklifts.
