And lithium ion can charge faster than lead acid.

So, you know, you can get one hour charge.

Some of your best devices out there can charge 80% in 30 minutes now, right?

Like whichever device you use, like a phone or even your EV.

And even within lithium ion technology, there's like different flavors.

with various trade-offs.

So if you want to store more or you want to run longer, it's called an energy cell.

And if you want it to use for fast response, it's called a power cell.

So those types of power cells made it to the UPSs of today.

Or a more, let's say, a recent derivative of that has been the battery backup units, or what they call DBUs, right, in some of the large hyperscalers.

And the big difference between these two is UPS is AC input, AC output.

It's giving you that sinusoidal good power quality and all of those power smoothing aspects on the AC front.

Whereas battery backup units are all DC and it's just for backup.

It's not for power smoothing or things like that.

Yeah.

So I think a lot of these old, let's talk about like cloud with CPUs and normal servers were just AI servers, right?

So I think that's where the big difference is coming in terms of the differences in the load and how that affects performance.

not just the density, but all aspects of safety and whether they can actually do the job.

So lead acid was pushed out because the density was not good, right?
