Frequently Asked Questions
Frequently Asked Questions
What type of battery does a forklift use?
Today's choices are either traditional lead-acid or state-of-the-art lithium-ion batteries. The battery you choose depends on the specific application(s) in your operation.
Are Li-ion batteries safe for a lift truck?
OneCharge Li-ion batteries fully match trucks’ specs and are safer for the truck than lead-acid batteries on different levels:
- No voltage drop during the normal discharge cycle, which can damage truck parts
- Single battery operation means the battery stays in the compartment and eliminates daily shift changes
- Li-on cells are a closed system, so no sulfating of the compartment and surrounding areas on the truck (no acid spills)
- No gassing occurs while charging, so there's no hydrogen to worry about
What are the cost benefits of a Li-ion battery compared to lead-acid?
The total cost of ownership of a Li-ion battery, compared to both lead-acid and internal combustion powered trucks, is generally 20–40% lower over the course of 2–4 years.
How long does it take to charge a Li-ion battery?
Generally speaking, we set up the combinations we provide so they will charge from zero power to full in two hours or less. A typical shift would normally include two 15-minute breaks and one 30-minute lunch. Putting the battery on charge during these times will replenish 50% of the battery capacity. OneCharge also highly recommends opportunity charging whenever the battery is not in use.
Is it OK to leave a lithium battery plugged in to the charger?
You can leave the battery plugged into the charger whenever it’s not being used! The charger will be automatically turned off by the battery management system when the battery is full.
What about the “memory effect” with respect to a Li-ion battery?
OneCharge lithium-ion batteries do not have a charge memory, or a “memory effect”. There is no set charging procedure required, except to put it on charge whenever it’s not being used.
Do you have to “water” a Li-ion battery?
Do you have to cool a Li-ion battery after charging?
When will a Li-ion battery get so hot it catches fire?
A Li-ion battery that uses LiFePO4 chemistry will experience thermal runaway (catch fire) at 518°F degrees. The OneCharge battery management system will shut down the battery if it reached 150°F degrees. OneCharge emphasizes that our batteries are unlikely to catch fire based on the combination of multiple cells used in the batteries. The LiFePo4 chemistry is 20+year-old technology, widely tested and used, and is the safest chemistry that exists for the lift truck market.
Are lithium batteries considered hazardous materials? How do you transport a lithium-ion battery?
Lithium batteries for lift trucks are regulated as a hazardous material under the U.S. Department of Transportation's (DOT's) Hazardous Materials Regulations. OneCharge lithium batteries conform to all applicable requirements and are safe in usage and transportation. Contact us directly for shipping info on any orders you place.
Can lithium batteries be shipped internationally?
OneCharge currently ships batteries to Canada, Mexico, and South America.
Do you need a ventilated room for Li-ion batteries?
Do you need to equalize-charge a Li-ion battery?
Do you have to unplug the Li-ion battery from the lift to charge it?
OneCharge batteries have a separate charging port located next to the battery management system.
Is there any required daily or weekly maintenance for a Li-ion battery?
No. All OneCharge Li-ion batteries are WiFi-enabled for online monitoring and troubleshooting.
Is it OK to fully discharge a Li-ion battery?
Yes, but we don’t recommend it. The cells perform better and will last longer with lower depths of discharge, which is why we recommend opportunity charging.
Can I use my old/existing charger to charge a Li-ion battery?
Possibly. Check with your OneCharge representative and/or the OneCharge engineering department regarding the make and model of the charger you want to use. If it can be programmed to work with our battery, we’ll test and approve it for use.
Do Li-ion batteries weigh the same as lead acid batteries?
Individual Li-ion cells are much lighter and ballast is added to the battery case to match the correct weight needed for the truck to work properly. OneCharge makes custom batteries to match the specs listed on the manufacturers' data plate of each lift. The final weight can be adjusted to accommodate the use of certain lift truck attachments (paper roll clamp, carton clamp, bale clamp, etc.).
Can Li-ion batteries operate in cold temperatures?
Yes. OneCharge offers two different FROST packages that enable Li-ion battery operation in extremely cold conditions (as low as -22°F). The FROST packages will ensure optimum performance without the capacity or run-time losses normally associated with lead-acid.
How do you recycle a Li-ion battery?
Currently, OneCharge has a program in place that will accept the battery, disassemble its components, and recycle the metals and electronics. Spent cells will be sent back to the manufacturer for recycling or re-purposing, with the appropriate documentation delivered to the end-user to prove proper disposal.
How long can a Li-ion battery stay inactive / be stored and still function normally when required?
Usually, 9–12 months, stored with the battery fully charged, then turned off during the storage period. We also recommend that you put the battery on charge at least once every 3 months during the storage period. This feature is especially good for seasonal business or rental fleets.
Who is the largest manufacturer of lithium batteries?
The traditional lead-acid companies are starting to make lithium versions, but are a bit late to the party because their infrastructure is lead-acid based and well over 100 years old. Estimates show that market penetration is only around 7–10% in the material handling world. No one is officially tracking the sales data yet, so realistically – it's anybody's guess. OneCharge is one of the leading lithium batteries manufacturers for lift trucks in North America. We've been making lithium batteries for forklifts since 2014.
