Battery numbers on accessories are not always what they seem, which is why AULA adds a small but pointed phrase to the F87 Pro V2's spec: its 10000mAh cell is labelled "true capacity". Understanding a true capacity battery label helps you read that figure correctly, both for what it promises and for what it does not.
Quick Answer
AULA's "true capacity" label says the F87 Pro V2's 10000mAh rating reflects the real size of the cell, not an inflated marketing number. It describes how much charge the battery holds, not how long the keyboard runs, and AULA quotes no runtime in hours. The cell powers the 2.4GHz and Bluetooth modes, and the board carries a 1 Year Local Warranty via Evetech. Evetech's price for the F87 Pro V2 is R899.
🔋 What the label is telling you
Capacity in milliamp-hours (mAh) measures how much charge a battery can store. On some accessories, the printed figure is optimistic, rounded up, or quoted for a combination of cells in a way that flatters the number. A "true capacity" label is the maker's way of saying the figure on the box is the actual capacity of the cell fitted.
Here, that means 10000mAh is meant to be taken at face value as the size of the tank.
⏱️ Why capacity is not runtime
A bigger tank does not tell you how far you will drive, because consumption varies. The same is true here. How long a charge lasts depends on:
- Lighting. Key lighting, the glow wrapped round the case and an audio-reactive dot display all run at once on this board. Bright, busy lighting draws much more than a dim, static setting.
- Connection. Wireless use over 2.4GHz or Bluetooth draws on the battery; the USB-C cable does not rely on it.
- Use. Hours of typing and gaming draw more than a keyboard sitting idle.
Because those variables swing so widely, AULA quotes capacity and leaves runtime out. That is more honest than a single hours figure measured with the lights off.
📊 How 10000mAh sits in AULA's range
Set against three of AULA's other wireless keyboards, this cell comes out largest. The L99, with its touchscreen, carries 8000mAh. The F99 Max, with its smart screen and knob, also carries 8000mAh. The magnetic HERO 75 HE runs on 8000mAh too. So this board offers a quarter more capacity than those boards, which is meaningful given how much lighting it has.
🧪 Can you check the capacity yourself?
Not easily. Measuring a battery's true capacity takes specialist equipment and usually means opening the device, which is not worth the risk on a keyboard under warranty. The practical check is simpler: note how your own typical use drains the battery over a few weeks, and you will know what to expect.
🔁 Will the cell fade over time?
All lithium batteries lose some capacity with age and charge cycles. You can slow that by avoiding running the battery completely flat, keeping the keyboard away from heat, and not leaving it unused on a full charge for months. If long wireless sessions matter to you, starting with a larger cell also means more headroom as it ages.
The rest of the board suits long sessions too: a tenkeyless layout, 8000Hz polling, SOCD, gasket suspension padded with seven layers, and switches that swap without solder.

Frequently Asked Questions
Does "true capacity" mean the battery lasts longer?
Not directly. It means the 10000mAh figure is the real cell size. Runtime still depends on lighting and use.
Why would AULA add the label at all?
To signal that the capacity figure is genuine rather than inflated, which is a common concern with accessory batteries.
Which modes use the battery?
The 2.4GHz and Bluetooth wireless modes. When connected by USB-C, the keyboard is not relying on it.
How does the F87 Pro V2 compare with other AULA boards?
Its 10000mAh cell is larger than the 8000mAh in the L99, F99 Max and HERO 75 HE.
Should I test the capacity myself?
No. It needs specialist gear and often opening the case. Tracking your own usage over a few weeks is more useful.
Will the battery lose capacity over time?
Yes, as all lithium cells do. Avoiding heat and full discharges slows the decline.
