株式会社日本蓄電池 Product Lineup

Restore alternative battery packs that fit existing spaces using the latest cells. This allows you to avoid costly equipment replacements and enables continued maintenance. Small lot production We flexibly respond to the need for "just a few as spares." Large order quantities are not necessary. Complete reproduction of shape and connectors We meticulously reproduce special-shaped plastic cases, unique connectors, and even the lengths of lead wires. You can resume operation simply by swapping them out on the day they arrive. Performance improvement with the latest cells Compared to older cells, the latest cells have higher energy density, which can provide added value such as "extended operating time" and "longer lifespan" even in the same size. Optimal design of safety circuits (BMS) We not only connect the cells but also incorporate overcharge and over-discharge protection circuits. We optimize the protective functions to ensure safe use even in older charging environments. Design based on physical analysis is also possible Even if specifications or drawings are not available, we can analyze your used battery pack and design a replacement. Please understand that we may not be able to meet all requests.

Old equipment still often comes with NiCad and nickel-metal hydride battery packs. Some battery packs are already discontinued, and the manufacturer can no longer provide them. This can be very troublesome when you want to continue using equipment that is still operational. If we can take the actual item, it is possible to manufacture a replacement (new product). <Advantages of Replacement> 1. You can directly replace the existing product. (If it has lead wires or connectors, we can almost always make a proposal.) 2. The size and usability remain the same, and we can also propose an increase in capacity. *Please note that there may be cases where we can only propose up to the same capacity. 3. If connector terminals for discontinued batteries can be obtained, we can accommodate that. (We can also handle reinstallation of existing connectors.) 4. There may be cost reductions compared to purchasing from the manufacturer.

We will restore and manufacture nickel-cadmium and nickel-hydride battery packs that have been discontinued by the manufacturer with equivalent performance. For those who are struggling with "I still want to use the equipment, but there are no batteries," we support longevity with small-scale production starting from just one unit.

Batteries installed in picking carts, small transport equipment, and various devices require limited space, sufficient capacity, and safety. At our company, we leverage the technology developed for AGV and AMR batteries to design and manufacture battery packs for small devices, considering specifications on a case-by-case basis.

In product development, batteries often face the constraint of needing to fit into the "remaining space inside the casing." Our company manufactures fully customized compact battery packs, tailored to your device design, from battery type selection to shape and wiring specifications. ■ Wide Range of Battery Support We accommodate a wide range of batteries, including mainstream lithium-ion batteries (Li-ion), as well as nickel-cadmium batteries (Ni-cd) and nickel-metal hydride batteries (Ni-MH), which still have strong demand in industrial settings. We propose the optimal cells based on voltage, current characteristics, cycle life, and other application requirements. ■ Advanced Customization Capabilities We offer flexible responses to detailed specification changes, including optimization of shape through changes in cell arrangement (series or parallel), connector specifications, and lead wire lengths. ■ Commitment to Small Lots and Diverse Varieties If you have a case where "we need a small quantity of a few to several dozen units, and major manufacturers have turned us down," you can rest assured. We respond swiftly, from prototype production of a single unit to small-scale mass production. If you want "a special shape" or "to create a compatible product for an old model at a low cost," please feel free to consult with us.
