This Ridgid 18V starter kit stands out for high capacity batteries and unusually strong value, especially for tools that drain fast like blowers, shop vacs, trimmers, and rear handle saws. The 8Ah packs are described as beasts with noticeably better runtime and power than 4Ah batteries, and the included charger adds extra utility. The main caveats are weight and some listing confusion, since the pictures and box did not always match the contents. Registration for the lifetime warranty also came up as an important step.

  • Homeowners building a cordless tool fleet, because the 8Ah batteries deliver noticeably longer runtime and stronger power for blowers, vacuums, trimmers, and shop vacs.

  • Cordless tool owners who need backup charging during outages, because each battery set includes a charger and can speed up recharging when power is out.

  • Ridgid ecosystem users who want longer runtime without swapping packs, because the 8Ah batteries fit high-drain tools and extend use between changes.

  • Battery-heavy DIYers who want maximum capacity per dollar, because the kit works out to about $7.125 per amp-hour and beats a $10 per amp-hour rule of thumb.

  • Shoppers who need a perfectly clean, single-box delivery, because some orders arrived partial, in retail packaging, or with unclear prior opening.

  • Buyers who need a guaranteed complete shipment on the first delivery, because some orders arrived with only part of the kit before the rest showed up later.

  • Users who need a lightweight battery on handheld tools, because the 8Ah packs are heavy on blowers and wackers.

  • Owners who want hassle-free warranty registration, because the 8Ah kit can throw errors when applying for LSA.

Went through for me, thank you so much! I'll sell my two older 4 aH for cheap and keep these. I never got the LSA for the two older batteries (long story grrrr), but they still hold a great charge after a couple of years of use.

I plan to use the batteries for the shop vac and fan. The 4Ah are fine for my other tool needs and I have one nice, light 1.5Ah battery that I got for cheap in another deal for short-use power tools, for small projects. It's not a huge weight savings, but convenient for rotating tires and such. Doesn't even use one bar of the 1.5, so even the 1.5 is overkill.

ETA: oh, yea, one of my kids is still small enough to ride the 12V power wheels, modified to use these Ridgid batteries. It zooms and 8 Ah should provide much better run time.

The number seems to be rising. 155 now. Could be they are adding due to popularity, or canceled orders are going back into the inventory? Or something else.

It's just a question. I have plenty of the 4 amp max outputs. Wondering if you can return them and keep the 2 8amp hours ,

No, you can't return the 4 Ah batteries. You do have the option of selling them locally if you don't need them.

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.
Watch out I use a shoulder strap for my wacker and would rather have alight battery on my blower. For the Vac 8amp is the deal but they are heavy.

I ordered very late last night, and I received a tracking number from one of those weird shipping companies (OnTrac)....deliveries questionable. I was outside to get a package one time and watched this kid toss it on the steps instead of giving it to me.
It currently shows shipped with a delivery of Wed.

I did a ship to store and there is a tracked shipment on the move. Since the pictures and description didn't all match I figured if it isn't the 2x8 and 2x4+charger I can deal with it at pickup instead of FedEx and returns and what not.
