Battery types

You’ll find various types of batteries installed in forklifts, each offering different levels of performance. Selecting the right battery type is crucial for meeting your forklift’s expected performance and managing ongoing costs, including battery life cycle considerations. Currently, two main types of batteries are commonly used in forklifts.

Lithium-ion Battery (Li-ion)

Jungheinrich designs and manufactures high-performance lithium-ion batteries, engineered for exceptional power delivery and energy retention, resulting in a longer lifespan and maintenance-free operation. Fast charging offers additional benefits, ideal for meeting tight production schedules and handling high order volumes. With just 30 minutes of charging, you achieve 50% battery power, while 80 minutes provides a full 100% charge.

*Depends on battery capacity and performance.

Lithium-ion (Li-ion) batteries deliver consistent power, allowing forklifts to operate efficiently throughout their lifespan. While the initial price may be higher compared to lead-acid batteries, Li-ion batteries prove to be a valuable long-term investment with a strong return on investment (ROI).

Lead-acid Battery

Lead-acid batteries consist of lead plates and sulfuric acid, which serves as the electrolyte solution. While they are generally more affordable than lithium-ion batteries, they can be used in various environmental conditions. Lead-acid batteries can provide long hours of operation on a single charge. However, they are heavier and take longer to fully charge compared to lithium-ion batteries. Additionally, they require regular maintenance to ensure optimal performance.

Forklift Charger Technology

The key performance indicator for forklift chargers is their efficiency, which contributes to longer battery life. When selecting a charger, it’s essential to consider quality, reduced charging time, and lower electricity costs. We offer a variety of chargers tailored to your specific usage and needs. Each type has different performance characteristics based on how operators utilize them.

Stationary Chargers

Find the suitable stationary chargers for your batteries. Jungheinrich provides you with the most suitable charger for your highly efficient lithium-ion as well as your conventional lead-acid batteries – whether in single, two or three-shift operation, for light or heavy operations, with or without intermediate charging. You get the perfect charging technology for practically any battery type and any periphery. For maximum battery lifecycles and performance as well as optimum availability of your vehicles. The Jungheinrich high-frequency charger SLH 300/300i and our charger SLT 150 with transformer technology are suited for any 24, 48 and 80 volts applications.

On-board Chargers

High frequency technology ensures safe and protective charging in various power classes – for all industry sectors and all battery types. More than 60 years of experience in manufacturing electric drives has benefitted the development of our on-board chargers. On-board chargers or integrated chargers by Energy and Drive Systems are perfectly suited for operations without battery changes or as pick-up device. Their handling is really simple: At night or in between shifts, the charger can be plugged into a regular 230 volts power outlet. Various power levels ensure numerous possibilities of application for any industry sector and battery type, while our high frequency technology allows for protective charging, thus prolonging the battery’s lifecycle.

What Causes Should You Be Aware Of?

Battery Deterioration

Battery degradation can be caused by several factors. Heavy-duty use without breaks leads to overheating, which accelerates wear and shortens battery lifespan. Insufficient charging, frequent deep discharging, using the wrong type of stationary charger, and exposure to extreme temperatures all contribute to faster battery degradation. Additionally, operating the battery in humid or dusty conditions without protection can further accelerate deterioration.

Decline in Battery Performance

The battery is the core power source for an electric forklift, essential for transporting goods efficiently in a warehouse. When battery performance declines and it can no longer deliver optimal power, production processes may be delayed. Here are key factors that contribute to reduced battery performance:

Battery Life: Over time, battery cells naturally deteriorate, especially with extended use, leading to diminished performance.
Improper Use: Heavy-duty tasks without sufficient breaks and inadequate charging times can significantly reduce battery performance. Following recommended charging guidelines can help extend battery life.
Charger Quality: Using counterfeit or low-quality chargers results in inadequate energy supply and charging in excessively hot or cold conditions further impacts battery efficiency.
Incorrect Battery Type: Selecting the appropriate battery type is essential, as using an incompatible battery may hinder forklift performance. Some batteries are not suited to certain conditions.
Lack of Maintenance: Regular inspections and maintenance are crucial, especially for lead-acid batteries. Cleaning battery terminals and checking levels daily will help sustain battery performance.

Battery Capacity and Longevity

Battery capacity and lifespan are crucial factors impacting the performance and efficiency of your operations. Battery capacity, measured in Ampere Hours (Ah), indicates how much energy a battery can store and deliver. Forklift batteries typically range from 110–500 Ah or 24, 48, and 80 volts, depending on the forklift’s size and type. In terms of longevity, lead-acid batteries last around 1,500–2,000 charge cycles, while lithium-ion batteries offer approximately 3,000–5,000 charge cycles, depending on usage and maintenance.

Battery Discharging

Battery discharging occurs as energy is delivered to the forklift during use. Discharge rates depend on factors like duty intensity and operating hours. To prevent premature battery deterioration, discharge should ideally not fall below 20%. Keeping the charge between 20% and 80% helps maintain battery quality and longevity. Additionally, prolonged heavy-duty use can cause overheating, so managing discharge levels is essential for protecting the battery’s lifespan.

How to Maintain Your Battery?

Proper care and maintenance of your battery can significantly reduce costs and boost operational efficiency. Here are some essential battery maintenance tips:

How to Charge Your Battery Correctly?

Complete Charging Cycle: Fully charge the battery after use to avoid short, incomplete charges that can reduce battery lifespan.
Use the Correct Charger: Ensure that the charger is compatible with your battery’s capacity and type for optimal performance.
Choose the Right Charging Environment: Charge in a clean, well-ventilated area that’s free from humidity, dust, and extreme temperatures. Avoid charging in overly hot or cold conditions, as this can impact battery health.

Check Acid Level (For Lead-Acid Batteries Only)

A weekly check of the acid level in lead-acid batteries is essential. Ensure the acid level is at the specified mark. If it’s low, top it off with distilled water—not acid—to maintain the correct balance and prevent damage.

Monitor the Battery Status on Display

Keep an eye on the battery signal alerts on the forklift display. The display indicates battery capacity, available charge, and temperature levels during operation or charging, helping you track battery health and prevent overheating.
