【マキタ互換】ウェイトレー8Ahバッテリーを半年酷使した結果

A long time ago, I bought a compatible battery for my weightless mower for about 3,000 yen, but it stopped charging after just one use.
I bought replacements, but they all broke. I ended up buying about 17 of them.
I swore I'd never buy another one, but recently I bought this 8Ah battery.
I intended to make a video saying, "It was no good after all," and used it heavily for six months... but the results were unexpected.
I fully charged it, used it until the mower stopped, measured the voltage, and even opened it up to check the circuit board. I'll explain why the old battery broke and the differences with this one.
*This is my personal review, not a verification video.
I felt this 8Ah battery was good, but this doesn't mean all weightless mower batteries are good.

分解検証されてる他チャンネル動画によると、内部に使われているSAMSUNG製21700セルの公式データシートではライフサイクルが6A充電35A放電250回で60%容量を保証で、ライフサイクル的にはそんなに長くない…っていう評価だったと思いますが桃さんの充電回数実績からすると2年を超えた辺りで実容量が5.0Ahを切る辺りまで低下するのですね…
ちなみに6:07動画内の草刈り機はバッテリー側のカットオフ機能で止まってないです。草刈り機側の過放電保護機能で止まってますね。バッテリー側のカットオフで止めた場合は2〜4Vのパルス電圧で止まります。12.5Vを下回った時点で回路的に切り離すのでこんな電圧になるみたいです。充電器に刺せばリセットされて無事復活します。
バッテリー側のカットオフの状態を見たいのであれば(バッテリーには良くないですが😅)草刈り機では無く、ブロワや扇風機、もしくはマキタ純正では無い工具の方が良いです。要するに工具側が低性能(過放電保護機能が無い)だとバッテリー側のカットオフが働きます。
ウチの父はブロワでしょっちゅう互換バッテリーを壊してきましたが、新型Waitleyになってから一度も壊して無いですね👍
カットオフ搭載して、遂にプロユースに耐えられるようになったのですね。
6ahを70%下回ったら充電して使い倒しています。トラブル無しです。
少しだけ知識のある素人用が従来のウェイトレイなんでしょうね。
残留2/5位で充電するのかなり使えます。
最近は過放電防止のカットオフ回路が着いたので残留0まで使っても過放電前で放電停止になります。空で放置せずに直ぐに充電して置くと劣化防げます。
親方のように半年間使ってレビューしてくれる人ばかりなら参考になるんですけどね。
ウェイトレーの純正充電器ではできません
そこで自動車用の12.8V用の充電器で12.5V以上に電圧を上げてやりました（屋外で充電）
純正充電器に接続し充電可能を確認 １００％ 充電できました
個人の責任でやっています 燃えると危険なのでご注意ください
