■製品説明■
単四電池と同じサイズのバッテリーで、3.7V に対応する機器に使用可能です。
高信頼・大容量の 10440 セルにセイコーインスツル製 IC を使用した信頼性の高い保護回路を装着し、トップクラスの性能及び、安定性を実現した高めたリチウムイオンバッテリーです。
セルは主にコバルト及びマンガンを使用した三元系バッテリーセル。

■取扱いの注意点■
(※使用前に必ず付属の取扱説明書をお読み下さい)
コバルト/マンガン系に関わらず、リチウムイオンバッテリーは 2.5V 以下の過放電状態に陥ると、バッテリーの寿命を極端に縮めてしまい、最悪の場合バッテリーが駄目になります。

保護回路は微弱放電、自然放電の過放電を抑える事は出来ません。

バッテリーの長期保管の場合、冷暗所にて保管してください。

冷蔵庫等での保存は結露で錆及び液漏れが発生する場合もありますので、お止め下さい。

非常に低価格で販売されている リチウムイオンバッテリーは発火及び爆発例もあり、安全上の観点からお勧め出来ません。

リチウムイオンバッテリーの発火は水では消火できず、専用の化学消火剤が必要です。
