As we reported 3 months ago, Hilti is launching a new 22V “flash charging” Nuron cordless power tool battery, B22-260.

Aside from an initial teaser, Hilti has not yet provided any details about how or why this new Nuron battery charges faster, or the type of Li-ion battery tech it uses.

From the case aesthetics, I am led to assume it uses pouch-style battery cells rather than the latest high performance tabless-style Li-ion battery cells, but that has not yet been confirmed.
It’s also unclear whether this battery requires special chargers to achieve Hilti’s fast-charging claims.
Without any concrete details, I took to Google to see if there were any updates.
According to Google’s AI Overview, the new Hilti B22-260 flash-charging Nuron 22V cordless power tool battery is indeed “optimized” for special chargers.
But they also say this Hilti Nuron battery has a charge capacity of 2.6Ah.
2.6Ah?

That doesn’t sound right.
Hilti has a bunch of new batteries, including 9Ah and 13.5Ah batteries.
The new flash-charging battery looks to be around the same size as their 18-cell batteries.
A 2.6Ah charge capacity for the new Hilti Nuron Flash-charging battery seems too low and woefully inaccurate.
That’s the problem with AI – it’s always highly confident even if it’s factually wrong. Or maybe it’s right and this new Hilti 22V battery really does have a 2.6Ah flash-charging battery, but I cannot imagine that being true.
I know the 2.6Ah charge capacity claim must be inaccurate, but I also don’t have any official information from Hilti.
I asked Hilti USA for clarity but have not yet heard back.

Sounds like it “thinks” 260 in the part number is 2.60Ah.

As Abe Lincoln said, “Don’t believe everything you read on the internet.”

I wonder if you can ask the AI about its confidence level (As a percentage) that it is indeed 2.6 amp hours. Would it think that all its information is 100% accurate or would it be intelligent enough to know its not always right and assign a realistic value generally or a specific value for this particular question. I think AI has a long way to go but it has already proven the ability to solve complex problems. Give it some time and maybe these types of issues will go away. If we can easily see the issues now why wouldn’t we be able to improve and eliminate them over time? I do think its overrated and overused considering current capabilities but if you anticipate the future it probably will be incredibly capable.

I saw a Youtube video a few weeks ago from a media event in which the Hilti rep explained that the first number on the battery (22) is the nominal voltage, while the second is its ‘total energy capacity’, presumably in watt-hours:

For example, take the 22-290, which is supposedly 13.5 ah. 22×13.5 = 297.
If that approximation holds we should expect the 22-260 to be in the ballpark of 11-12 ah.
I haven’t figured out what kind of cells are inside it, but pouch would explain the geometric design on the exterior of the pack, as well as the impressive performance numbers.

Is it possible they are making a lower capacity battery to have a very rapid charge item? But it 2.6ah does seem a bit low in the scheme of the family. 5.4 maybe more sense.
