[Saitama/Rainy Season June] Safe Collection of Swollen Mobile Batteries & Power Tool Batteries | Covers Warehouses, Garages in Saitama, Kawaguchi, Koshigaya, and Batteries Uncollectible by Municipalities | On-site Pickup 7,700 Yen

Battery Collection in Saitama Prefecture

In Saitama Prefecture during June, as the rainy season begins, people are increasingly tidying up indoor spaces and warehouses, and conducting inventory checks and equipment reviews in garages and workshops. This is a time when consultations often increase regarding swollen mobile batteries, old laptop batteries, power tool batteries, and batteries from rechargeable devices found stored away in garages, with people saying, "We know it's dangerous, but we don't know how to dispose of it" or "We want to dispose of it while we're cleaning up during the rainy season."

Saitama Prefecture has many areas with detached houses and storage in warehouses/garages. Lithium-ion batteries (rechargeable batteries) left in high-temperature and high-humidity environments often deteriorate due to moisture and rising temperatures, leading to cases where abnormalities are discovered in June. In particular, June marks the start of the rainy season with high humidity and rising temperatures, which can lead to prolonged periods of high temperature and humidity in warehouses, garages, and cars, potentially causing condensation and internal damage.

Deteriorated batteries can lead to serious accidents such as swelling, overheating, leakage, and ignition. Depending on the storage location, such as apartment buildings, warehouses, factories, or commercial buildings, the potential damage in case of an accident can be significant.

Furthermore, June is a time when batteries stored for many years are discovered during rainy season cleanups and inventory checks, and internal deterioration due to humidity and rising temperatures tends to become apparent.

On the other hand, lithium-ion batteries are sometimes treated as uncollectible (difficult-to-process items) by municipalities. This leads to cases where dangerous batteries continue to be stored because people were "refused at the cleaning center," "cannot find a place to bring them," or "don't know where to take them for disposal during the rainy season cleanup."

It is also pointed out that if these batteries are mistakenly disposed of as general waste, accidents could occur during the collection and intermediate processing stages.

In response to this situation, we will continue our initiative in June to strengthen the safe collection of lithium-ion batteries that tend to accumulate in Saitama Prefecture, aiming to reduce fire risks and create a safer environment during the rainy season, by safely collecting even batteries that are swollen, deformed, or overheating through specialized channels.

✅ Background and Objectives

In recent years, the number of lithium-ion batteries (rechargeable batteries) owned by households and businesses in Saitama Prefecture has continued to increase.

June, in particular, is a time when the deterioration of previously stored batteries tends to become apparent due to the overlap of rainy season cleanups, inventory checks, and equipment reviews.

It is not uncommon for batteries whose disposal methods are unknown to be discovered all at once during organization or equipment replacement.

The background to this increase in ownership includes the following factors:

- Proliferation of electric bicycles/commercial assist bicycles (increased commuting and delivery use in Saitama Prefecture)
- Common use of power tool batteries for DIY and construction sites
- Long-term storage in warehouses, factories, and businesses (discovered during equipment replacement or reorganization)
- Multiple ownership of mobile batteries/portable power supplies due to online shopping and disaster preparedness stockpiling
- Discovery of stored batteries during rainy season cleanups and inventory checks

Moreover, June, with the start of the rainy season bringing high humidity and rising temperatures, is a time when the deterioration of long-term stored lithium-ion batteries is likely to become apparent.

Batteries with advanced internal damage pose a risk of serious accidents such as swelling, overheating, leakage, and ignition.

It is particularly pointed out that if swollen mobile batteries or laptop batteries are mistakenly disposed of as general or non-combustible waste, fire accidents could occur in collection vehicles or intermediate processing facilities.

In places like apartment buildings, warehouses, factories, and workshops, the risk of accidents can increase even while the batteries are still in storage.

However, many municipalities in Saitama Prefecture treat lithium-ion batteries as "uncollectible" or "difficult-to-process items." This results in dangerous batteries continuing to be stored because people are "refused at the cleaning center," "told they cannot be placed in collection boxes," "told that swollen items are not handled," or "don't know who to consult."

In response to this situation, to promote the proper disposal of swollen batteries, overheating batteries, and deteriorated lithium-ion batteries that tend to accumulate in Saitama Prefecture, thereby reducing fire risks and ensuring safety during the rainy season, our company will continue to provide services in June with a collection system that thoroughly implements fire prevention management, insulation treatment, safe transportation, legal compliance, and proper transport to specialized facilities.

✅ Common Concerns

In Saitama Prefecture during June, consultations regarding the disposal of lithium-ion batteries tend to increase, often triggered by rainy season cleanups, warehouse organization, and equipment reviews.

Here are some common concerns:

- We have a large number of power tool batteries in our warehouse or workshop and want to dispose of them all at once (We want on-site collection in Saitama Prefecture).

- During garage organization, we found swollen mobile batteries/old laptop batteries and are having trouble disposing of them.

- We have no place to dispose of lithium-ion batteries that were deemed "uncollectible" or "difficult-to-process items" by the municipality (cleaning center).

- We are concerned that the batteries may have deteriorated due to humidity, condensation, being left in a car, or outdoor storage.

- Factory/business premises
