A swappable battery only helps if you have a second cell: planning around the SC900 MAX

The AULA SC900 MAX's headline feature is a battery you can lift out and replace in seconds. That is genuinely useful, but it only removes downtime if there is a second, charged cell waiting. Planning a swappable battery mouse routine means being clear about what you have on day one, and making the most of the design even with a single cell.

Quick Answer

The SC900 MAX's quick-swap trick depends on having a second charged 400mAh cell, and the listing does not include one. With a single battery, treat it like any rechargeable mouse: top it up over USB-C during breaks, or play wired while it charges at up to 8000Hz. The removable cell still makes long-term replacement simpler than in a sealed mouse, and Evetech backs the mouse with a 1 Year Local Warranty. Evetech's asking price is R749.

📦 What you start with

The SC900 MAX ships as a tri-mode wireless mouse with one 400mAh lithium battery fitted under a cover on its base. The listing describes a battery that can be swapped for a charged one in seconds, but it does not promise a spare in the packaging. So on day one, you have one cell, and the swap feature is a capability waiting for a second battery rather than something you can use straight away.

That is worth knowing before you buy, so your expectations match the box. It also changes how you should think about the feature: rather than a reason to never charge, see it as insurance for later, and as a way to keep the mouse going for years rather than until its original cell tires.

🔌 Avoiding downtime with one cell

A single battery does not leave you stuck. The SC900 MAX has two good ways to keep going.

Charge during natural breaks

The mouse charges over USB-C. Plugging in between matches, over lunch or while you step away keeps the cell topped up without interrupting play.

Play wired while it charges

The USB-C cable is also a full connection. On the cable the mouse still polls at up to 8000Hz, the same ceiling as the 2.4GHz receiver, so switching to wired when the battery is low costs you nothing in responsiveness. The only change is a cable on the desk until the charge is back up.

Build a simple routine

• Charge at the end of each day so you start with a full cell.
• Keep the cable within reach of your mouse pad.
• Use a lower polling rate, such as the 1000Hz default, for casual play and desk work, since higher rates generally use more power.
• Set the base switch to off when you are done.

🔋 Why a removable cell is still worth having

Even if you never own a second battery, the design pays off over time. Lithium cells lose capacity as they age. In a mouse with a sealed battery, a tired cell can mean opening the shell or retiring the mouse. On the SC900 MAX, the cell sits under a cover and lifts out, so replacing it later is a far simpler job.

That longer view is a big part of the appeal. The mouse's other qualities, 62g with the battery fitted, up to 8000Hz polling on the receiver or cable, and DPI steps from 400 to 30,000, will stay useful long after the original cell has done many cycles.

🛒 If you want a second cell later

Only use a battery made for this mouse. A cell that looks similar may differ in size, connector or protection circuitry, and fitting the wrong one risks damage. If you want a spare or a replacement, ask Evetech about AULA-compatible options for the SC900 MAX rather than guessing.

When you do have two cells, the routine becomes simple: one in the mouse, one charging, and a swap whenever the level drops. The exchange itself takes seconds.

Sealed-battery and removable-battery designs share shelf space among Evetech's gaming mice, while a separate wireless mouse page keeps to cable-free models. Black, White and Red are the SC900 MAX's three finishes.

Frequently Asked Questions

Does the SC900 MAX include two batteries?

The listing does not promise a spare. Expect one 400mAh cell fitted in the mouse.

Should I fit any 400mAh cell I can find?

No. Only use a battery made for this mouse. Similar-looking cells can differ in size, connector and safety circuitry.

How do I avoid downtime with one battery?

Top up in breaks, or run on the cable, which keeps the 8000Hz ceiling while the cell refills.

Is the swappable design still worth it with one cell?

Yes. It makes replacing an aged battery much simpler than in a sealed mouse.

Where would a spare come from?

Ask Evetech about AULA-compatible cells for the SC900 MAX, rather than buying an unknown battery.

How long does changing cells take?

AULA describes it as a matter of seconds: open the base cover, lift the cell out and fit the charged one.
