Disposal Guide for LiPo Batteries from DIY Earphone Repairs
- The other day, I replaced the LiPo battery in my earphones myself in an attempt to fix a non-charging issue. Experiencing firsthand the dilemma of what to do with the old, unnecessary battery, I’ve put together a guide on “how to correctly dispose of LiPo batteries generated from DIY repairs." In reality, local governments have established small lithium battery collection systems, so checking your local municipality’s disposal rules first is a reassuring first step.
Official Sites Referenced
As reliable sources of information on disposal rules, I checked the following sites:
- JBRC (Japan Portable Rechargeable Battery Recycling Center) “Recycle Flow and Target Battery List"
- JBRC Cooperative Store & Municipal Collection Spot Search Page
- Municipal pages regarding the handling of lithium-ion batteries
Based on these, I created a safe disposal guide for earphone LiPo batteries.
Correct Disposal Methods for LiPo Batteries
Do not charge even after use, and insulate the terminals
- The unusable battery after replacement can be left as is, but be sure to insulate the positive and negative terminals with vinyl tape or the like.
Check for swelling or damage
- JBRC only accepts member-manufactured batteries that are free of swelling and damage.
- Confirm that the battery is free from water exposure or abnormalities before collection.
- If you have any concerns, consult your local government counter (cleaning center).
Take to a JBRC Cooperative Store or Municipal Collection Service
- If it is made by a JBRC member manufacturer, you can drop it off at the “yellow collection box" installed in electronics retail stores, home centers, etc.
- At the nearby Yamada Denki, there was no yellow collection box, and the battery had to be handed directly to a store clerk.
- Some municipalities have collection stations or curbside collection, so municipal collection is also carried out in parallel.
Tips
- Wrapping the terminal tape thickly in three layers provides peace of mind. This prevents short circuits during handling.
- If swelling is observed, do not use it and consult immediately. This reduces the risk of ignition.
- Since municipal collection systems vary, it is recommended to check your local government’s disposal page in advance.
Checklist: Summary of Disposal Steps
- Check the battery collection method on the municipal website, etc.
- Leave the replaced battery without charging.
- Apply insulation tape to the positive/negative terminals.
- Check for swelling and damage.
- If it is made by a JBRC member, bring it to a cooperative store or dispose of it via the municipal collection system.
- Take non-eligible or abnormal batteries to the municipal counter.
