BSLBATT’s Certification Position
BSLBATT holds UL 2580 certification on its 51.2V and above forklift battery range, covering Class I and Class II trucks, and is among the first lithium forklift battery manufacturers in the industry to hold both UL 2580 and ISO 9001. Packs are also built to CE and IEC 62619.
In the UL 2580 destructive sequence, BSLBATT packs passed short circuit, crush, multi-axis rotation, and drop testing, then continued to operate and accept charge following the sequence. In the fire exposure test the pack self-extinguished without spreading beyond the unit.
Certified models are available across the range, including:
- B-LFP48-460MH — 51.2V / 460Ah, UL certified, IP65 enclosure
- B-LFP48-615MH — 51.2V / 615Ah, UL certified, IP65 enclosure
- B-LFP36-820MH — 38.4V / 820Ah, UL certified
Certificates for these models are available on request. Ask your BSLBATT representative for the file number and verify it directly.
Frequently Asked Questions
Is UL 2580 required for forklift batteries in North America?
Not universally by law, but effectively yes for most serious buyers. Many corporate risk, insurance, and safety departments require a Nationally Recognized Testing Laboratory (NRTL) listing before lithium batteries are approved for indoor use. Even where no regulation mandates it, an unlisted pack can fail an insurance review or a fire marshal inspection after an incident — at which point the cost of the listing is trivial compared to the cost of the outcome.
What is the difference between UL 2580 and IEC 62619?
UL 2580 tests a complete motive battery pack against mechanical and thermal abuse, and was written for electric vehicles. IEC 62619 covers safety requirements for secondary lithium cells and batteries used in industrial applications, including forklifts. They overlap but are not substitutes. A forklift battery is best specified with both: UL 2580 for abuse resistance, IEC 62619 for industrial-application safety.
Does a UL 2580 certificate cover every model a manufacturer sells?
No. UL listings are issued to specific model designations within a defined scope. A manufacturer can hold UL 2580 on one voltage platform and not on another. Always match the model number on your quotation to the model number on the certificate, and confirm the listing is active rather than withdrawn.
Is UN 38.3 the same as a safety certification?
No. UN 38.3 is a set of eight transport tests required to ship lithium batteries by air, sea, or road. It demonstrates the battery can be transported safely under defined conditions. It is not a test of safety during use, and it should never be presented as equivalent to UL 2580 or IEC 62619.
How long does a UL 2580 listing stay valid?
A listing remains valid as long as the manufacturer maintains it through UL’s surveillance programme and the product continues to conform. Listings can be withdrawn or allowed to lapse. Verify the current status in UL’s Online Certifications Directory rather than relying on a certificate PDF supplied by the vendor.
Does certification affect insurance or workplace safety approval?
Frequently. Insurers and safety officers commonly require an NRTL listing as a condition of approving lithium batteries for indoor industrial use. Providing a verified UL 2580 file number typically shortens that approval considerably. Check with your insurer before purchase if a specific standard is referenced in your policy.
