Looking at the shape I am not sure these two are much different. I may be wrong but looks like the batteries are inside the 2 red cylinders. The base black plastic may just be empty. A good way to compare, are both the same weight?and now the question: Both of these 12V batteries are rated as 3.0 Amp hour batteries. Logistically that seems odd due to the difference in size. But here's the part that really confuses me: The smaller batter is rated at 36 watt hours...and the larger battery is rated at 32 watt hours. So my questions are....
If the voltage is the same, and both batteries have the same amp hours...shouldn't they have the same watt hours ?
And all I care about is run time...should I focus on watt hours or amp hours ?
Why doesn't size matter.....the smaller battery has a larger watt hour rating ?
Thanks in advance.
If you want to know what is inside, open itthe smaller one is 6.7 ounces and the larger one is 14.3 ounces
I would have thought the same thing..same volts, same AmpHours = Same watt hours.
I am about to buy 2 more and am wondering if I am just paying for a psychological factor of bigger size.
If we really wanted to complicate the issue...the larger battery comes in a 4.0 or a 6.0 Amp hour rating...and the smaller one can be had in a 2.0 or 1.5 Amp hour rating.
If they are all 12v maybe the manufacturer has a problem with mathsI was/am mainly confused about the middle 2 that are both rated at 3.0 Amp-Hours...but here are the 4 that I own....The smaller size comes in 1.5 Amp hours...and the larger size also comes in 6.0 Amp hours.
A bit of a drift but: I have found that rechargeable batteries that are not used regularly tend to die an early death. Replacing the batteries is often close to the price of a new tool with a new battery. Since I don't use my power tools very often (except for my Black and Decker cordless screw driver) I have begun using corded tools. It's a little hassle dealing with the extension cord etc. but the tool never disappoints and they are pretty powerful. Just sayin'

.....I have one set of twin drill/driver RIGID from Home Depot...... my RIDGID battery powered skilsaw .....
If you are an infrequent tool user, a flashlight that runs off your drill battery is a great way to keep the batteries in use. Keeping the batteries charged helps prolong their life.
