Review: T〇poのモーションセンサー用に買いました。 変わった型番だなと思ったけどすぐに見つかって一番安かったので コレを買いました。しっかりした製品で取り合えず使えます。 20個セットを買ったけど嵩張ります。紙袋に個包装の電池が 5個セットずつくらい繋がって入ってます。ちと不便かな。 シャシンを撮るのが面倒だったけどそのうちアップするかも。 中身は問題ないので安いものを探してる人はどうぞ。
Review: BMWのキーの電池がCR2450で、５年ほど変えなくても動いてましたが、最近車のコンソールにキーの電池低下が頻繁に警告されます。 この電池、あまりお店に置いてなく量販店などに行かないとないので購入しました。 今まで使っていた古い電池は3.03Vで新電池は3.37Vと１割は高い値を示しています(写真)、また動作確認もしましたが問題なく車のロックを解除できました 販売単位の個数が１０個と多いのですがこの電池は５年ほど置いてても電圧低下はほとんどないので安心して置いとけると思います

BMWのキーの電池がCR2450で、５年ほど変えなくても動いてましたが、最近車のコンソールにキーの電池低下が頻繁に警告されます。 この電池、あまりお店に置いてなく量販店などに行かないとないので購入しました。 今まで使っていた古い電池は3.03Vで新電池は3.37Vと１割は高い値を示しています(写真)、また動作確認もしましたが問題なく車のロックを解除できました 販売単位の個数が１０個と多いのですがこの電池は５年ほど置いてても電圧低下はほとんどないので安心して置いとけると思います

格安で購入出来て良かったです。 最近は、ネットワーク接続タイプ（アレクサ対応など）の小型機器や自動車のスマートキーにも使われており、１００円ショップでも売り切れている事が多いですから… 電池容量が不明なので、長持ちはあまり期待出来ないかな？ 数が多いので、余りをメルカリなどで転売する方も多いですね。
