Here are the benefits of using lithium. There are two types of lithium: lithium iron phosphate and lithium cobalt oxide. However, for forklift batteries, lithium iron phosphate is found to be more suitable from a safety perspective. Lithium iron phosphate ion batteries can achieve fast charging and high current discharge, and their cycle life at 80% discharge is about four times that of lead batteries. In addition to good charging efficiency, they also eliminate the need for water replenishment, leading to cost reductions in purified water expenses and labor costs. 【Features】 - 70% reduction in annual costs - Lifespan is three times that of lead - Can be rapidly charged in a quarter of the time of lead - One lithium battery can operate a unit fully for 24 hours - No need for water replenishment - Zero harmful substances, contributing to the global environment *For more details, please refer to the PDF document or feel free to contact us.

The lithium-ion battery can operate for 24 hours without replacement, which results in a reduction in the number of forklifts needed. It also helps to reduce costs for annual inspections and repairs. 【Measurement Overview】 ■ Measurement Period: June 4, 2021 ■ Industry: Beer Factory ■ Location: Kanagawa Prefecture ■ Forklift Model: 7FBH15 (7676HR) manufactured in August 2001 　Battery replaced in July 2013 ■ Lead Battery: VCF8N 545Ah 48V ■ Lithium-ion Battery Capacity: 560Ah 48V *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a trial case of our lithium-ion battery replacement service for forklifts implemented in other factories of a packaging plant. Compared to other factories, the downtime of forklifts is less, and even with intermediate charging, the battery level decreases. Due to continuous high-density operation, lead batteries are under strain, resulting in a shorter lifespan. Therefore, we introduced lithium-ion batteries. By operating one unit for 24 hours, we can reduce the number of forklifts by 50%. Additionally, due to their longer lifespan, we can reduce costs by over 70% annually. 【Measurement Overview】 ■ Measurement Period: May 11, 2021 – May 27, 2021 ■ Industry: Manufacturing ■ Location: Saitama Prefecture ■ Forklift Model: 7FB15 ■ Lead Battery: 485Ah 48V ■ Lithium-ion Battery Capacity: 560Ah 48V *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a trial case of our lithium-ion battery replacement service for forklifts, conducted at a 24-hour operating paper manufacturer using a 3.5-ton bale clamp. The currently installed lead battery operates an average of 4.2 hours per day. After the lithium replacement, the operating time increased to a maximum of 12.1 hours. The lifespan of the lead battery, which is 3.5 years, is calculated to extend to 15 years with the lithium-ion battery, resulting in a 79% cost reduction. [Customer Overview] ■ Paper manufacturer factory, raw material input process ■ Toyota 3.5-ton counterbalance bale clamp 7FBJ30 ■ Lithium-ion battery: 80V 560Ah ■ Lead battery: approximately 3 years lifespan (high-capacity specification of 470Ah) ■ Manufactured in January 2016, 8357 hours as of May 2021, average of 4.2 hours per day ■ Currently installed lead battery: manufactured in August 2019 *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a trial case of our lithium-ion battery replacement service for forklifts in a -25°C cold storage facility using a lead battery charger. We were using a Toyota 1.5-ton reach truck, model 7FBRS15. The lithium-ion battery is 48V 280Ah. After the lithium battery replacement, the operating time was 12.7 hours, with a maximum discharge time (usage time) of 4.1 hours (5/13) and a charging time (using a separate charger) of 7.0 hours (5/13). [Customer Overview] ■ Cold Storage: -25°C ■ Toyota 1.5-ton reach truck 7FBRS15 ■ Lithium-ion battery: 48V 280Ah ■ Since the GSP signal does not reach the warehouse, a specially designed GSP device and BMS were used for testing. *For more details, please refer to the PDF document or feel free to contact us.

At the 3PL logistics center, we were using two 1.5-ton counterbalance forklifts (FBT15PN-80B) equipped with 390Ah48V lead batteries, operating 24 hours a day. However, battery replacement was necessary approximately every three years, leading to high costs. To compare, we introduced one unit each of 560Ah48V and 280Ah48V lithium-ion batteries, using one rapid charger and an onboard charger for charging. As a result, we found that the 560Ah lithium capacity had about a 20% longer operating time. [Comparison Results] ■ Lithium Capacity Comparison - The 560Ah has about a 20% longer operating time. ■ Lead Batteries - Insufficient charging time during use was a major cause of the three-year lifespan. - If the introduction of lithium allows for sufficient charging time for lead batteries, it is expected that the lifespan of lead batteries will also be extended. *For more details, please refer to the PDF document or feel free to contact us.
