SERDADU88 The ampere hour, in simple terms, tells something about how long the power tool can operate before it needs to be recharged. If comparing two batteries with the same battery technology and same voltage rating, a battery with twice the amp hour rating should last about twice as long. In practice there may however be some variations to this. Also, batteries with a higher amp hour rating in practice can also often let the power tool deliver a slightly higher peak power due to the ability to deliver a higher current.|I {Saw|Noticed} This {Terrible|Horrible} {News|Information} About Slot Yes001 {And i|And that i} {Had to|Needed to} Google It
