Ryobi Impact wrench deal got me looking at HD for other Ryobi deals and found this one and I think its pretty slick.

Normally a 2-pack is $99.

FYI, four compacts are the capacity same as one 4AH battery, which is $99 everyday, therefore the 4 compacts for $99 is not a true deal, it's the same price as the 4AH everyday price. So with the overall battery capacity the same, here's how you decide what to buy:

Get the larger 4AH Lithium+ for $99 if you:
- do heavy usage, like a large job: hours of drilling, spinning saw, blower, weed trimmer, or any serious project like doing your deck
- don't mind the heavier weight (it's not that much more)

Get the 4 compact Lithium+ for $99 if you:
- plan on using multiple tools and don't want to swap batteries on a job
- want the tool to be as light as possible
- are willing to make sure you keep charging your batteries and rotate during heavy usage

If you're on the wall, go with the single 4AH battery, because many tools run out somewhat quickly and waiting for a charge, even at a 30min window per battery, can be a PITA

These are 2.4 Ah, the 2-pack has two 4 Ah batteries.

I was wrong and ibur is correct, these are the 2.4 AH batteries not the 4 AH batteries that come in the 2-pack for $99 (although finding the AH on these was difficult and the only description on both of them is "18v High-Capacity"). Not nearly as slick as I thought. Mad

However the 4-pack for $99 is for the 1.3 AH batteries, not the "high-capacity" versions.

i generally like ryobi tools.....

but the home depot people NEVER list the Mah rating of their ryobi batteries....which is arguably the most important specification...

and this deal makes them look like the bigger capacity 4500 mah(?) batteries....

my guess is that hd is misleading (on purpose ?) as most folks don't know


another note is that homedepot online and in store returns from my experiences do not play nice together and sadly i know one of thier district managers

i recently did a return from a hd online purchase and they ended up giving me store credit on a card, which is by design i surmise as a certain percentage of customers never will use them.....this is a common business pratice as it essentially creates money for the retailer.

Both the P108 (4.0Ah) and the P105 (2.4Ah) are considered "high capacity". Perhaps this is a bit misleading, but IMHO either of these batteries beats any "compact" battery for use in any high drain tool any day of the week.

Why? It all comes down to current drain. The compact batteries have a single string of cells inside whereas the "high capacity" batteries (better called full-height) have two strings. Every cell in the single string batteries must deliver the full current required for a job, whereas every cell in two-cell batteries must only deliver half.

For more information See This Page [toolboyworld.com].

Read the negative reviews for the new P261 Impact Wrench on Home Depot's website and I'll bet you each of these reviewers was using an old NiCD pack or a compact battery when they tested the tool. Any battery will make the P261 run. But with a P108 the tool is MUCH more powerful than with a P102.

For low current drain tools, a compact battery is a good choice. I usually use a compact battery in radios, fans, flashlights, and even in drills and impact drivers UNLESS I'm planning on doing something that will really tax the tool, like boring a deep hole with a spade bit .

On to the comparison.

We can objectively calculate cost per energy for the various Ryobi battery deals.

P185 Kit = P105x3 for $89.00. That's $89.00/(2.4Ahx3) = $12.36/Ah
P122 Kit = P108x2 for $99.00. That's $99.00/(4.0Ahx2) = $12.38/Ah
P181 Kit = P102x4 for $90.00. That's $90.00/(1.3Ahx4) = $17.31/Ah
P170 Kit = P102x2 for $49.97. That's $49.97/(1.3Ahx2) = $19.22/Ah

The kits with two P108 and three P105 are basically the same cost per energy, and the kits with the P102 are more expensive. Unless you need to operate three or more tools simultaneously I'd suggest the P122 kit over the P185 so you have fewer batteries to keep up with, and the built-in power level meter on the P108 is pretty cool.

It's still a useful post. Going by their rated capacity, your deal is 3x 2400mAh, or 7200mAh combined capacity. That's less than the 8000aAh combined capacity for the 2 Lithium Plus battery packs. Then again, your deal is $10 less.

For me, the slight premium for the higher 4000mAh battery packs is worth it, but I can see the calculus being different for other users in certain situations (like a group project where multiple people might each be using cordless tools concurrently).

It's all good.
