Question about rechargable batteries for lawn mowers, etc.

First let me say I came here with this question because I know there are a lot of smart people here. I realize it is very off topic but I need objective help. I want to buy this neat 80 volt rechargeable Kobalt lawn mower from Lowes. One of Lowes selling points is you can use the same 80 volt batteries in other 80 volt Kobalt lawn devices, such as the 80 volt rechargeable weed wacker. Here is the problem I have with this claim. The lawn mower is 5 amp hour, while the weed wacker is 2.5 amp hour. When I was taught basic electricity in high school fifty years ago that will be problem for the 2.5 amp weed wacker yet the Lowes sales person assures me it will work.

What are your thoughts on this? Thanks.

I don't see it as a problem - are you concerned that the charger will damage the weed wacker?

I would have expected the weed wacker to take the charge it needs and it is just that it also has the capacity to charge a device with a larger battery, such as the mower.

Always pop back and let us know the outcome - thanks

I am concerned about the lower amp (not voltage) weed wacker which I am buying as well.

If you mean amps rather than ampere hours then they are a function of the device not the charger. Even though the charger can deliver 5 amps the lower current device will only take 2.5 max. I see no reason for concern.
