Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Anbernic RG Cube / RG Cube Video — 3.7V Li-Polymer Replacement Battery (AHB104180)
This is a 3.7V 4800mAh Li-Polymer replacement battery for the Anbernic RG Cube, RG Cube Video, and RG Cube Retro handheld gaming consoles. It uses OEM part number AHB104180 and matches the original cell's dimensions at 81.50 × 39.60 × 10.30mm. Install it when the original battery no longer holds charge across a full play session.
- RG Cube series compatibility: The RG Cube, RG Cube Video, and RG Cube Retro share the same battery bay geometry and connector pinout, so one cell covers all three variants. The BMS on each model reads the same voltage window — 3.0V cutoff at the low end, 4.2V at full charge.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the RG Cube platform. The onboard charge IC accepted the new cell without fault flags, and the BMS protection circuit triggered cleanly at both the low-voltage and over-current thresholds.
- Fuel gauge calibration on first install: After fitting this cell, run one complete play session to automatic low-battery shutdown before recharging. The RG Cube's fuel gauge IC sets its empty reference point against the first full discharge — skipping this step causes the percentage display to read inaccurately for weeks.
Why the RG Cube fuel gauge jumps or reads wrong after a cell swap
The RG Cube uses a coulomb-counting fuel gauge IC that builds its discharge model against the original cell's internal resistance profile. A fresh cell has lower internal resistance, so the gauge misreads state-of-charge until it recalibrates. This shows up as the percentage jumping — often from 40% down to 5% without warning, or sitting at 100% longer than expected. Three to five full discharge-and-recharge cycles reset the learned curve and bring the display back into step with actual capacity.
Console shuts off unexpectedly while the battery still shows charge remaining
This happens when the cell's voltage sags below the BMS cutoff threshold under peak load — typically during GPU-intensive scenes or when wireless is active alongside high screen brightness. The fuel gauge percentage lags behind the real-time voltage drop, so the display still shows 15–20% when the protection circuit cuts power. To confirm this is the cause, charge to full and watch whether the console shuts off again at the same type of load. If it clears after two to three full conditioning cycles, the cell was not yet at rated capacity — new Li-Polymer cells often need cycling to reach their full 4800mAh output.

Frequently Asked Questions
The RG Cube battery percentage jumps straight from 30% to 2% and then the console dies — is the new cell faulty?
The cell is not faulty. The RG Cube's fuel gauge IC calibrated its discharge curve to the old cell's internal resistance, and a new cell behaves differently until it learns the new profile. Run three to five complete discharge-to-shutdown and full-recharge cycles without interrupting them mid-way. After that, the percentage steps down steadily instead of jumping.
My RG Cube is only charging to about 80% and then stopping — what's happening?
The charge IC applies a conservative current limit when it first sees a new cell, and on some RG Cube units this causes the first charge cycle to terminate early. This is not a faulty battery or a faulty console — it clears after the first full discharge cycle. Drain the console to automatic shutdown, then charge uninterrupted to 100%; subsequent charges will accept the full capacity.
Play time on the new battery feels noticeably shorter than the original — did I get a lower-capacity cell?
New Li-Polymer cells do not deliver their full rated capacity straight out of the box. The AHB104180 is rated at 4800mAh, but the first few cycles will fall short of that figure as the cell's chemistry settles. Run three to five complete charge-to-full and play-to-automatic-shutdown cycles, and measured endurance will increase each time until it stabilises at rated capacity.
