Up to 8,000 charge/discharge cycles We at Optimum Battery Co. Ltd develop and produce high-performance LiFePO4 and NI-ZN batteries. Our LiFePO4 batteries can be charged/discharged more than 2,000 times at full capacity - a feat that many of our clients appreciate. At a lower discharge level, these products can reach up to 8,000 cycles - that's six times more than standard SLA batteries, four times more than Li-ion types and five times more than NiMH/NiCd models.
Advanced QC regimen ensures high quality products
We are one of the first battery suppliers in mainland China to have implemented an ISO/TS16949 system and obtain a certificate issued by NQA. We follow ISO 9001:2000 and ISO 14001:2004-certified guidelines, and our 100 inspectors check our raw materials strictly in accordance with IEC standards, ensuring every batch is qualified for mass production. And our models carry CE, UL and RoHS marks, allowing for easy distribution in Western Europe, North America, Oceania and the Middle East. What's more, our items come with two-year warranties.
Five-plus new models developed monthly
Every year, we reinvest 30 percent of our annual sales in R&D projects, allowing our 30-member R&D team to develop at least five new models monthly. And using our in-house molding workshop, we can create an ODM sample for you in as fast as 20 days.
