HP ST09 Extended Life Notebook Battery【純正バッテリー】

通常のバッテリーをつけたまま追加装着できる HP ST09 Extended Life Notebook Battery という純正バッテリーを紹介いたします。

装着場所

WWAN スロットのすぐ上にあるのが拡張バッテリーポートです。

容量

下のセカンダリーバッテリーと表示されているのが ST09 です。

設計寿命 300 サイクルの通常バッテリーよりいくらか容量は大きいことがわかります。

バッテリーとしての持ちはスペック通りです。あまり負荷のかからない作業なら両方合わせて 8 時間ぐらい使える感じになります。

その他の機能

裏側に LED がついていて大体の残量がわかるようになっています。単一保有だとあまり意味はないですが、複数保有している人には便利かもしれません。

駆動時間以外の意外な利点

8570w に装着すると手前に傾斜する形になってくれます。人それぞれかと思いますが、完全に水平よりもこちらのほうが使いやすいのではないかと。

また、高さが上がることになるので、例えば以下のような利点もあります。

• 置く場所が濡れていたりしても本体が汚れにくい。また、おいている机に液体をこぼしてしまったときにも被害が及びにくい。
• ゴム足がなくなったりすることを防げる。
• ST09 未装着で布団のような柔らかい場所に置くとファンをふさいでしまうが、ST09 をつけていればそうならない。

動画のほうがわかりやすいかもしれません。

ST09 は装着したままドッキングステーションに装着できますが、BB09 は排他利用になります。

その代わり、BB09 はより大容量です。
