About this replacement
Trust GXT 35 Wireless Laser Gaming Mouse — 3.7V Li-ion Replacement Battery (SLB-10)
This is a 3.7V, 1050mAh Li-ion battery for the Trust GXT 35 wireless laser gaming mouse. It replaces part number SLB-10, the original cell that powers the GXT 35's onboard receiver and optical sensor. When the original cell degrades, this swap restores full wireless operation without replacing the mouse.
- GXT 35 platform fit: The GXT 35 uses a single Li-ion cell on a 3.7V rail. The SLB-10 form factor — 43.22 × 31.38 × 7.26mm — matches the original housing cavity and connector orientation exactly. No modification needed.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a GXT 35 unit. The BMS held stable voltage across gaming load spikes from DPI switching and click actuation. No false low-battery cutoffs were triggered during testing.
- Post-swap reconnection step: After fitting this battery, unplug the USB receiver and reinsert it before powering the mouse on. The GXT 35's wireless link re-initialises on receiver detect — skipping this step is the most common reason the mouse appears dead after a battery swap.
Mouse pointer stuttering near end of battery life on the GXT 35
As the SLB-10 cell drops below approximately 3.5V, the GXT 35 reduces its wireless polling rate to conserve power. This shows up as visible cursor lag or stuttering that isn't caused by interference or driver issues. The optical sensor continues functioning, but packet transmission to the USB receiver becomes intermittent. If the cursor recovers immediately after plugging in a fresh battery, the old cell — not the mouse — was the fault.
GXT 35 not reconnecting after battery replacement
A full power loss clears the GXT 35's active pairing state. When a fresh battery goes in, the mouse may not reconnect automatically even if the receiver is still plugged in. Remove the USB receiver, wait five seconds, then reinsert it — the mouse should respond within a few seconds of the receiver re-enumerating. If it doesn't, hold the pairing button on the underside of the mouse for three seconds with the receiver already inserted.
