Lead-acid batteries can degrade due to a chemical process known as battery sulfation if they are not properly maintained. Maintaining the water level in the electrolyte is crucial to preventing this. Maintaining the health of a lead-acid battery requires periodically topping it off with distilled water.
Maintaining a large fleet’s battery bank can be an expensive and time-consuming task. To carry out this process, you must assign qualified staff members and make sure they adhere to all safety precautions.
Because they don’t require frequent maintenance operations or to be topped down with water, lithium-ion batteries are significantly more straightforward to maintain.
Lithium-ion batteries don’t require regular watering. However, lead-acid batteries require it to maintain their power. The lengthy and expensive maintenance process associated with lead-acid batteries is one of their key disadvantages.
Infrastructure and Resources Available for Charging
You should also allow for extra storage space for the lead-acid batteries that you might need to carry around with each forklift. It’s also essential to make sure the storage area is safe; it should be kept at room temperature or colder, kept out of direct sunlight, and away from heat sources like hot air ducts.
Additionally, you must set aside funds and adhere to a proper lead-acid battery charging procedure. It is a labor-intensive procedure that requires the battery to be taken out of the forklift and put on the appropriate charging rack for each charge. Due to its weight, the battery may need to be moved from the forklift to the charging rack and back again by skilled workers using lifting equipment.
The majority of buildings nowadays have infrastructure for electrical supply that is appropriate for lead-acid batteries. The wiring, outlets, and battery charges won’t require any large purchases.
Choosing lithium-ion batteries eliminates the need for extra storage infrastructure because each forklift requires one battery. You can leave the battery inside the forklift while it charges, which simplifies and lowers the cost of the procedure. Just drive your forklift to a power outlet and attach the battery to a charger.
Li-ion batteries require a more considerable input current to charge because their rate of charging is significantly faster. An energy audit of your establishment could be necessary to determine whether your electrical infrastructure needs to be updated for Li-ion battery charging to be done efficiently. The adoption of Li-ion batteries to power your forklifts will incur a one-time expenditure.
Because lithium-ion batteries charge more quickly and efficiently than other types of batteries, you can save both space and personnel time. If you intend to buy lead-acid batteries, you should factor in these extra, frequently unnoticed infrastructural expenses.
On the other hand, as Li-ion battery chargers typically require a more significant input current, you might need to modify your electrical infrastructure before implementing Li-ion batteries.
Lead and sulfuric acid, the two high-risk substances that make up lead-acid batteries, could be a safety danger for you and your group. When performing maintenance, there is a chance that the workers’ skin and eyes could come into contact with sulfuric acid, so you must make sure that personal protective equipment (PPE) such as rubber gloves, an acid-resistant apron, splash-proof goggles, and face shields are worn.
When being charged, lead-acid batteries can release an explosive mixture of oxygen (O2) and hydrogen (H2) gasses. An explosion could occur if the charging room is not properly aired. Installing hydrogen sensors in the ceilings of the rooms where lead-acid batteries are charged is one of the necessary precautions.
When vented lead-acid batteries are overcharged, ancient ones, a very hazardous gas known as hydrogen sulfide (H2S), can be released. To make sure no one is exposed to this hazardous gas, you should leave the location if such an occurrence takes place.
Because there are fewer health risks for individuals using lithium-ion batteries than lead-acid batteries, they are regarded as being far safer. Because these batteries are totally sealed and do not need to be opened to be watered, there is less chance of sulfation, hazardous odors, or electrolyte spills than there would be with lead-acid batteries.
Compared to lead-acid batteries, lithium-ion batteries are regarded as being significantly safer. Any workplace should prioritize health and safety, and when employing lead-acid batteries, you need to budget for the costs of infrastructure, personnel, and training to provide a safe working environment.
Battery Energy Efficiency
Lead-acid batteries lose energy when they are charging, draining, or even just sitting still. Because lead-acid batteries only yield roughly 80% of the energy necessary to charge them, lead-acid batteries are energy inefficient and increase power expenses.
Since there are minimal energy losses and most of the energy consumed for charging—up to 99% in certain situations—is accessible as output, lithium-ion batteries can be regarded as significantly more energy efficient.
Because lithium-ion batteries have low energy losses and can produce more, they can help you save money on electricity. When compared to lead-acid batteries, which are infamous for leaking energy, you can anticipate savings of up to 30%.
