Forklifts are usually equipped with lead-acid batteries, which are essentially large-capacity batteries that can be recharged. These batteries are quite reliable. And, if you are planning to purchase a forklift battery, you may be curious to know the various components of a forklift battery, including how much sulfuric acid is in a forklift battery.
A forklift battery acid is essentially a lead-acid battery that is made up of multiple individual cells, which contain lead alloy plates that are immersed in an electrolytic solution, which usually comprises 65% water and 35% sulphuric acid.
So, if you’re purchasing a forklift battery to replace the existing one, there are many factors to consider that can impact the operational cost, as well as efficiency of the battery so that you end up with the right one for your forklift.

How Many Pounds of Sulfuric Acid Is in a Forklift Battery
Typically, a forklift battery i.e., a lead-acid battery consists of an electrolyte, which is a solution of water and sulfuric acid and plates of lead dioxide, as well as pure, soft lead. You can determine the weight of sulfuric acid in a forklift battery by using the following example.
We will assume that the sulfuric acid in the battery to be 18% of the weight of the battery and the amount of lead at 70% of the weight of the battery. So, if you consider a typical forklift battery, the average weight is around 2,400 lbs (approx.), it will contain around 2,400 x 0.18 i.e., 432 lbs of sulfuric acid and 2400 x 0.70 i.e., 1,690 lbs of lead.
How Many Gallons of Sulfuric Acid Are in a Forklift Battery
If you want to know how much sulfuric acid is present in a forklift battery in gallons, then here are some facts and figures. The sulfuric acid content will vary depending on factors such as the voltage and the AH/6hr rating of the forklift battery.
Frequently Asked Questions
Do All Forklift Batteries Contain Sulfuric Acid?
No, all forklift batteries do not contain sulfuric acid. Forklifts mainly use 2 types of batteries—lithium-ion batteries and lead-acid batteries.
Most of the forklifts on the market work on the old-school lead-acid batteries, which are also known as wet cell batteries. These lead-acid batteries contain cells and an electrolyte (a mixture of water and sulphuric acid) and lead plates, all contained in a plastic housing. These generate a chemical reaction that occurs between the sulfuric acid and the lead plates, thus powering the forklift. Lead-acid batteries usually last up to 1,000 to 1,500 charge cycles.
On the other hand, lithium-ion batteries, which are becoming quite popular in recent years contain a cathode, anode, electrolyte, separator and negative and positive terminals.
These are relatively smaller in size, low in maintenance, energy dense, charge more and are more efficient quickly compared to lead-acid batteries. Lithium-ion batteries last up to 2,000 to 3,000 charge cycles.
How Do You Calculate Sulfuric Acid in a Battery?
It is possible to estimate the amount of sulfuric acid in a forklift battery if you know the following details:
Using the formula, you can determine the weight of the sulfuric acid in the battery:
