### ⭐⭐⭐⭐⭐ hd4.40btに使用。充電可能になりました。
*by K***R on 17 January 2025*

長年使っているhd4.40btの充電ができなくなったので購入しました。 交換後、新品同様に充電が長持ちするようになりました。 購入を検討している方のために、下記書いておきます。 ・交換のために必要な工具はプラスのドライバーのみです。 ・端子類、配線は変える必要はありません。単純に既存の電池を置き換えるだけです。 ・電池交換のためにイヤーパッドを外す必要があります。ついでにイヤーパッドも交換してはいかがでしょうか。 おそらく、既に必要となった方がこの商品を見てるはずです。 ちゃんと使えるバッテリーですよ。おすすめ商品です。
