[Kanagawa, Rainy Season June] Safe Collection of Swollen Mobile Batteries Due to Coastal Humidity and Salt Damage | Yokohama, Kawasaki, Shonan Apartment Common Areas, Batteries Uncollectible by Municipalities, On-site Pickup 7,700 Yen

In Kanagawa Prefecture, June marks a period when tidying up, warehouse organization, and equipment reviews are common during the rainy season, leading to an increase in cases where stored lithium-ion batteries are discovered.

Specifically in Kanagawa Prefecture, there is a growing trend in consultations regarding the disposal of lithium-ion batteries, such as swollen mobile batteries, notebook PC internal batteries, and electric assist bicycle batteries, stemming from home organization, business inventory checks, and warehouse clean-ups during the rainy season.

For condominiums and multi-unit dwellings, it's also a time when management companies and owners often consult about batteries temporarily stored in common areas, management rooms, or warehouses, which are frequently found together during rainy season clean-ups.

Furthermore, in corporate offices and warehouses, it's not uncommon to find multiple batteries from old notebook PCs, tablets, or business equipment during rainy season tidying or equipment replacement, with disposal methods being unknown, leading to their continued storage.

Moreover, June's high temperatures and humidity associated with the start of the rainy season make it easier for internal degradation or abnormalities (swelling, heat generation) in previously stored lithium-ion batteries to become apparent.

However, lithium-ion batteries are often treated as difficult-to-dispose-of items by many municipalities, and there are cases where they cannot be collected as regular bulky waste or non-burnable trash.

"Refused by the cleaning center."
"I'm scared to dispose of it because it's swollen."
"I don't know where to take it."

For these reasons, batteries are sometimes stored for extended periods in a dangerous state.

Therefore, Marutto Honpo (operated by SYSTR Co., Ltd.), a company offering junk removal services, will continue to provide safe collection services for lithium-ion batteries, including swollen ones, within Kanagawa Prefecture throughout June.

We are committed to proper removal through specialized routes, fire-resistant management, and full compliance with laws, supporting the resolution of battery storage issues that pose an "invisible fire risk" in apartment buildings and businesses.

✅ Background and Objectives

In recent years, the number of lithium-ion batteries (rechargeable batteries) owned by households and businesses has been increasing in Kanagawa Prefecture. Batteries are used in a wide variety of devices, including mobile batteries, smartphones, notebook PCs, electric assist bicycles, and power tools.

Especially in urban areas, there are many condominiums, multi-unit dwellings, and office buildings, and it is not uncommon for batteries to remain temporarily stored in management rooms, common areas, warehouses, or backyards.

June, with the onset of the rainy season, is a time when indoor and warehouse organization and reviews are actively pursued, making the handling of stored batteries a prominent issue.

Additionally, due to the high temperature and humidity of the rainy season in June, the progression of internal degradation or abnormalities (swelling, heat generation) in lithium-ion batteries is a concern depending on the storage environment.

In Kanagawa Prefecture, in particular:

- Specific humidity and salt damage unique to coastal areas (humidity further increases during the rainy season)
- Temperature fluctuations in warehouses, storage sheds, and vehicles
- Long-term storage in common areas

These conditions can combine to potentially accelerate exterior deterioration, terminal corrosion, and internal damage.

On the other hand, lithium-ion batteries are often classified as non-collectible items (difficult-to-dispose-of items) by many municipalities, leading to situations where:

- They are not accepted by cleaning centers.
- Disposal methods are unknown.
- Safe disposal is impossible due to swelling.

As a result, proper disposal is not achieved, and storage continues.

In response to this situation, Marutto Honpo (operated by SYSTR Co., Ltd.), a provider of junk removal services, will continue to strengthen its safe collection services for lithium-ion batteries, including swollen ones, within Kanagawa Prefecture in June.

We are dedicated to reducing the risks associated with storing lithium-ion batteries and ensuring safety in homes, businesses, apartment common areas, and warehouses by thoroughly implementing fire-resistant management, insulation treatment, legal compliance, and proper removal to specialized facilities.

✅ Common Concerns

In Kanagawa Prefecture, June sees an increase in consultations for the disposal of lithium-ion batteries, often triggered by tidying up during the rainy season, warehouse organization, or office reviews.

Here are some of the common concerns we receive:

- Concern about fire and ignition risk from batteries stored in condominiums/multi-unit dwellings (including common areas and management rooms).

- Anxiety about swelling or terminal corrosion due to storage in areas with high humidity, coastal proximity, or frequent condensation.

- Being told by the municipality that batteries are uncollectible/difficult-to-dispose-of items (refused by cleaning centers, cannot be disposed of as general waste).

- Having multiple mobile batteries or smartphone batteries and being unable to determine which ones are in a dangerous state.

- Concern about handling internal batteries when disposing of equipment like notebook PCs, power tools, or electric assist bicycles.

- During the rainy season or equipment replacement, businesses, shops, and warehouses find batteries that pose a risk...
