Battery Rebuilding & Recycling
Rebuild weak or depleted batteries like brand new! We reuse the original housing and replace all internal battery cells with brand-new cells. Cut costs by more than half compared to buying new OEM batteries.
Send your battery using Japan Post "Letter Pack". After rebuilding is completed, we will refund the full 520 JPY shipping fee!
※ For larger batteries that do not fit in Letter Pack, please use Yu-Pack or Sagawa Express.
