This is a smokin deal. Currently you can get this - or a 2 pack of the 6.0 ah battery for $199.
If you are looking for higher capacity batteries this is a really good price and opportunity.
Don't forget to register for lifetime warranty- and you get 2 batteries for the price of 1 (when your current one hits end of life)

Smoking hot! I looked at the descriptions like you all did. I placed the order and I'm expecting 8Ah x2 + 4Ah x2 + Charger x1. That translates to 24Ah for $171 = $7.125/Ah. I haven't seen anything better than the rule-of-thumb $10/Ah in a long time! Rep'd OP!

I got 2x 8ah 2pks for $90/each on clearance about 2yrs ago, that was a real hunt and a time suck but worth it for me since I got it.

This is a pretty good deal especially if you need those bigger batteries and there's no hassle of going store to store to find the needle in a haystack.

These 8ah batteries are great for the blower, trimmer and rear handle saw

I rolled the dice also, fingers crossed!

I need the 2 x 8Ah, and plan to resell the 2 x 4Ah to further increase the slick factor!

I don't really need the batteries, but this is an unbeatable deal if both the 8amp batteries show up.
BTW, the 8 amp batteries are beasts. There is such a noticible difference in runtime and power compared to 4 amp ones...

Picture shows two 6amp and two 4amp. But if you have a blower or vacuum those 8amps will come in handy. I already have more batteries than I use so I'm out. This is a great deal for max power batteries.

Don't need it but can't resist it. Closest ive seen is $159 for the two pack 8ah but sold out before could get it. Like others may try to unload the 4ah kit on marketplace and get it net to $125 or so. Thanks OP. Thumbs up

That's exactly what I need the 8Ah for. I'm knee deep into the Ridgid ecosystem. My shop vac, weed wacker, and blower could all benefit from using the 8Ah for longer run time without having to swap.

Damn this ridgid deal is enticing! I just got their 2x 4Ah kit about 1 month ago for around $80. Might have to return that one if this deal goes through!
