Specifically designed for Yale lift trucks, our lithium-ion batteries are high-performance, maintenance-free forklift power sources engineered to enable optimized power management and peak warehouse efficiency. Validated as a fully-integrated system with the lift truck and charger, this complete energy solution delivers exceptional reliability and performance — all with the one-stop shop convenience and expertise of the independent Yale® dealer network.
The high energy density of Yale lithium-ion batteries supports long run times for fast-paced warehouses. The Lithium Iron Phosphate (LFP) chemistry at the core offers improved heat stability and tolerance, and longer life compared with other battery chemistries.
Unlike third-party lift truck battery solutions that mix and match components, our unified system eliminates battery-charger compatibility risks for a seamless, tightly integrated power solution. This system-level integration helps support communications between batteries and chargers directly with the lift truck, enabling early warnings and safety features. Easy-to-access external ports makes for simplified, operator-friendly charging.
Yale Battery Vision telemetry is included with lift trucks factory fitted with Yale lithium-ion batteries, empowering fleet and service managers with access to real-time battery and lift truck data.
Yale fully integrated lithium-ion lift trucks are not only manufactured with lithium-ion power, but are strategically designed around the smaller, lighter form factor of this advanced electric battery type. Engineering from the ground up rather than simply relying on a battery box replacement capitalizes on space savings, resulting in ergonomic and maneuverability advantages.
Gain the flexibility to change among battery types to suit your operation’s changing needs. Available on a broad lineup of Yale electric lift truck models, Yale Power Key™ is a one-of-a-kind solution that lets you switch among lead-acid, TPPL and lithium-ion batteries without any external accessories.
The expected product performance of is comparable to the internal combustion engine equivalent, except it provides instantaneous power for forklift acceleration and lifting. In addition, the battery provides power silently as it performs its lifting and product placement tasks.
Yes, there are charge ports on the side of the battery for charging. These are available in single- or dual-charging configurations.
No, the battery will communicate with the truck via the communication harness, and the SOC will be displayed on the truck display.
LiFePO4 or Lithium Iron Phosphate (LFP).
LFP batteries are:
The battery packs are assembled following carefully designed build processes to maintain the highest quality. Quality checks are completed at each step of the manufacturing process to fully comply with established quality standards. When battery packs have been completely assembled, an end-of-line test is performed to make sure battery packs comply with the test specifications.
Numerous validation tests were performed including drop, electromagnetic compatibility/electromagnetic interference (EMC/EMI), full operational temperature range, storage temperature, charge/discharge, fault and complete functional testing of all features.
Yes. The batteries are IP54 rated.
The BMS continuously monitors cell voltage, battery module temperature, and the overall pack current to help the cells remain within their specified safe operation zone for voltage, temperature and current.
During the charge process, the BMS constantly monitors the cell voltage, battery module temperature and overall battery pack current. The BMS continuously communicates with the charger via CAN messaging to adjust the charge current to keep the cells within their specified safe operation zone. If, at any time, any cell approaches an unsafe operation limit during charging, the BMS opens the charge contactor to stop the charging process to keep the cell safe.
Yes. Battery information is collected by Yale Vision when equipped on the truck.
Yale Battery Vision displays information such as SOC, low SOC events, over/under temperature events, faults, energy consumption, usage versus charging time and lift lockout events.
Some telemetry parameters can be used to indicate misuse of the battery pack — specifically, repeated over-temperature faults and repeated discharge over-current faults.
There is no maintenance required for the battery pack itself — simply follow proper operating procedures. The battery pack will take care of itself.
The battery pack should be stored in a dry environment within a 59 to 77 degrees Fahrenheit temperature range and less than 50% SOC to help maximize battery life.
Less than 3.5% per month.
The expected warranty life cycle of the battery is 3,000 charge/discharge cycles if operated at an internal battery temperature of 95 degrees Fahrenheit or less.
It is possible, following this procedure: Yale will determine if the battery pack can be refurbished after doing a check of each of the modules within the battery pack to determine the SOH spread between them. Based on those results, the refurbishment plan of action will be determined.

Custom Yale CAN communication protocol is used between the battery and charger. Therefore, only the recommended chargers can currently be used with Yale lithium-ion batteries.
No, lead-acid battery chargers cannot be used to charge Yale lithium-ion batteries. The chargers for Yale lithium-ion batteries cannot be used for lead-acid batteries, there is no charging profile for lead-acid batteries within the chargers.
No, Yale lithium-ion batteries use a proprietary protocol with Yale chargers. Additionally, Yale batteries require a power signal from the charger, which many third-party chargers do not offer.
Chargers are initially set up for specific output voltages. There is a configurable key in the connector that determines which voltage will be used while charging. The cable assembly can be swapped to reconfigure the voltage setting.
Yes. On certain models, you can use up to two chargers to charge a single battery. Dual charging must be equipped on the battery, and the battery will limit the total charge current allowed. Example: if charge current limit of the battery is 400 amps (A), but two chargers are plugged in at 300A each, the battery will only charge at 400A, not 600A.
No, the operator is prevented from driving if the battery is charging.
Yes, the charger can be ordered at the same time as the truck and delivered from the factory.
``
For three-phase chargers, four wire flying leads are included. These must be connected by a licensed electrician.
It depends on charger output voltage and amperage. Charger tech guides will indicate the required input current. Contact your local Yale dealer.
Warranty coverage extends up to two years.
As long as the charger is installed in an appropriate environment as specified, minimal maintenance is required. Periodic inspections should be performed per the manual.
