5Ah Batteries from DeWALT - What You Need to Know

We've known for a while now that lithium-ion batteries are only going one way; bigger capacity.

For around 3 years now we've seen a fairly constant upward trend from the best power tool manufactuers; more cordless power tools, higher capacity batteries. And now DeWALT has finally launched the successor to their highly acclaimed 4Ah 18v li-ion batteries. 5Ah.

DeWALT 5Ah 18v XR Lithium-Ion Batteries - What You Need to Know

Anytime larger capacity batteries come onto the market, the first thing we want to know is how much more runtime will they give our power tools?

And right after that, how long will the take to charge and how much heavier are they?

First things first, then. These new 5Ah XR packs aren't heavier than the 4Ah versions. And further to that, the 4Ah versions were actually lighter than the 3Ah packs!

Incredible, we know. But the reality is, the 5Ah 18v XR lithium-ion batteries DeWALT will be able to store up to 66% more charge than their 3Ah cousins, all within the same size, but lighter, pack.

Regarding charge times, we don't have any official figures on this yet. But we can surmise that the batteries will need to be on the charger for a reasonable amount of time to completely fill up, as is always the case with higher capacity batteries.

That, though, needs to be balanced against the fact that they'll last longer away from the charger! Which is, after all, the main attraction of higher capacity batteries.

And while we're talking about charge times, it's certainly worth keeping in mind the forthcoming arrival of the DCB102 charging station, which we caught a sneak peak at recently.

This beauty, in addition to having two USB charging ports, will charge 2 of any of the XR lithium-ion range. At once.

So with this, and a couple of 5Ah 18v batteries in your arsenal, you'll have no downtime during the day at all! (Pretty much...)

As the 5Ah batteries are part of DeWALT's amazing XR range, the battery benefits from all the smart features we've come to expect, and rely on. You can see the LED state of charge indicator, but what you can't see is what's going on inside the black and yellow pack.

Because it's an XR battery, the cells are monitored while charging and discharging, making sure there's no overheating, overcharging or deep discharge.

That means longer lifetime for the battery. The battery works in tandem with DeWALT's smart XR tools, all of which have intelligent switches and motors, so all of the extra capacity the battery holds will be drawn from it in the best way possible for the tool to get the job done as you need it.

Are DeWALT'S 5Ah XR Batteries Backwards Compatible?

This is another huge question for you to have answered, especially if you already how XR tools; will the new batteries work with them.

The short, simple and honest answer to this is yes.

These are XR batteries, therefore they'll work on any of DeWALT's 18v XR power tools, whether it's a brushless nailer, impact driver, jigsaw...you name it. And you don't need a new charger for the 5Ah batteries, they'll charge on any existing XR compatible charger.

What DeWALT Cordless Tools Will Benefit  Most from 5Ah?

Dewalt dcf886p2 5ahAs we've seen over the last few years, higher capacity batteries seem to be paired with brushless power tools. That's why when these new batteries land on the Toolstop website, you'll see them first with DeWALT's brushless tools, whether it's the nailer, the impact driver, the combi-drill or the drill driver.

Why brushless?

These power tools are already super efficient, so it makes sense to pair them with a bigger capacity battery. We've no data of the expected runtimes of these brushless, cordless power tools, but with up to 66% more runtime than 3Ah batteries, it could be you'll be working all day, only charging the batteries at night!

We can't wait to get the numbers on this!

That's what we have on the new 5Ah XR 18v batteries from DeWALT, coming August 2014. We'd love to hear what you think of them, so let us know in the comments below!

We're delighted you're happy with your tools! And there's no doubt that these packs will be more expensive than 3Ah or 4Ah versions. But the benefit of the higher capacity XR batteries will be seen when they're paired with DeWALT's brushless tools. It could be that they'll run all day without needing charged... We'll see.

We don't have prices on the batteries yet, but we've updated the article to state that the 5Ah XR batteries are compatible with the XR chargers.

I guess you can't charge a 5ah on a 4 ah charger ????
How much is the charger and a couple of batteries ???????L

The price of batteries is way to high as it is. my 6 piece dewalt 18v kit with 3x 4Ah batteries (bought from toolstop) last long enough its cheaper to buy a new tool with 2 new batteries and a charger than it is to buy batteries on their own so no need to upgrade especially going buy the price you will be selling them at.
