🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Battery model: For Anbernic RG353M
Capacity: 3500mAh
Rated voltage: 3.7V
Charge limit voltage: 4.2V
Battery type: Li-ion Polymer (Grade A cells, low internal resistance <60mΩ)
Compatible with: Anbernic RG353M, Anbernic RG 353M (metal shell version only)
Package include: 1 x battery
Give your Anbernic RG353M the reliable power it needs for extended retro gaming sessions. The RG353M stands out in Anbernic’s lineup for its premium CNC-machined aluminum alloy shell — a design that provides excellent durability and heat dissipation but also creates unique challenges for battery replacement. The metal housing has extremely tight internal tolerances; generic 3500mAh cells are often slightly thicker or have the connector cable positioned incorrectly, causing the backplate to bulge, the aluminum shell to not close fully, or the battery to shift during gameplay. This Li-ion Polymer replacement battery is specifically dimensioned to fit the RG353M’s precision-milled interior, maintaining the exact thickness (≤5.2mm) and small 2-pin connector placement required for a proper fit. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Why Metal Shell Matters — And Why Your Original Battery Has Degraded: The Anbernic RG353M was released as the premium metal variant of the RG353 series, featuring a 3.5-inch 640×480 IPS screen and a Rockchip RK3566 processor capable of emulating systems up to N64, Dreamcast, and PSP. The aluminum shell not only looks and feels premium but also acts as a heatsink, drawing heat away from the processor during gaming. However, this heat dissipation works both ways — the metal shell can get warm during extended play, and over 2-3 years, this consistent thermal cycling (heating and cooling) accelerates battery degradation faster than in plastic-shell devices. Common signs that your RG353M battery needs replacement include: the device no longer lasting through a typical gaming session, unexpected shutdowns during demanding emulators (especially N64 or PSP), the battery indicator dropping rapidly from 30-40% to 0%, or the handheld needing frequent recharging. This replacement battery restores the full 3500mAh capacity, giving you back 4-6 hours of mixed retro gaming. The low internal resistance (under 60mΩ) ensures stable voltage delivery during peak draw — critical for maintaining performance in PPSSPP or Mupen64 without frame drops or sudden shutdowns.
Compatibility and Installation Note: Fits Anbernic RG353M and RG 353M (metal shell) only. This battery is NOT compatible with the plastic-shell RG353V, RG353VS, RG351 series, or other Anbernic models. The RG353M’s metal backplate is held by four small Phillips screws — use a PH00 screwdriver for removal. After removing the screws, gently separate the backplate starting from the bottom edge (the battery is in the lower half). Use a plastic spudger to lift the original battery, disconnect the old connector by pulling the plug (not the wires), then connect the new battery. The small 2-pin connector is keyed and only fits one way — do not force it. After reassembly, if the device doesn’t power on immediately, leave it plugged into a 5V/2A charger for 10-15 minutes to activate the protection circuit. Always use a standard 5V/2A charger — do not use QuickCharge or Power Delivery fast chargers, as they can confuse the RG353M’s charge controller and reduce battery life.

Frequently Asked Questions

Yes, this battery is specifically dimensioned for an Anbernic RG353M battery direct fit in the metal alloy shell. The RG353M's aluminum housing has very tight internal tolerances — generic 3500mAh cells are often slightly thicker (over 5.5mm) or have the connector cable on the wrong side, causing the backplate to bulge or not close fully. For a replacement battery for Anbernic RG353M metal shell that fits without modification, this battery matches the original cell's dimensions with a thickness ≤5.2mm and uses the correct small 2-pin connector with the cable exiting at the proper angle. It is not compatible with the plastic-shell RG353V/VS or RG351 series. For RG353M metal shell battery thickness, this replacement is precisely matched. Please confirm your device is the RG353M (metal) before ordering — the metal shell version is heavier and has a different texture than the plastic variants.

Absolutely. The RG353M's Rockchip RK3566 processor draws higher current when running demanding emulators like PPSSPP (PSP) or Mupen64 (N64). For RG353M battery for PSP N64 emulation, this 3500mAh Li‑ion Polymer battery is built with grade A cells that have a low internal resistance (under 60mΩ), which means it can sustain the required discharge current (up to 2.5A continuous) without voltage sag. Many cheaper batteries use low‑grade cells that cause the RG353M battery no sudden shutdown — instead, the device shuts down at 30-40% indicated charge during heavy gaming. This battery maintains stable voltage output until the true low‑voltage cutoff. For 3500mAh low internal resistance RG353M, this cell provides reliable power for 4-6 hours of mixed retro gaming, depending on screen brightness and CPU load. The metal shell acts as a heatsink, helping to keep the battery cooler during extended sessions, which further improves voltage stability.

Use a standard 5V/2A USB charger (or a regular USB-A port on a computer). Do NOT use QuickCharge (QC) or Power Delivery (PD) fast chargers — they can confuse the RG353M's basic charge controller, leading to incomplete charging or reduced battery life. For RG353M battery charger recommendation, stick with the charger that came with the device or any standard 5V/2A adapter. After installing the new 3500mAh replacement battery for Anbernic RG353M charging, follow this calibration process: 1) Drain the device until it auto-shuts off (run a game or video to speed this up). 2) Charge it uninterrupted to 100% (about 2.5 hours with a 5V/2A charger). 3) Disconnect and use normally. For Anbernic RG353M battery calibration guide, this process helps the RG353M's firmware re-learn the battery's full capacity range and resets the charge controller's lookup table. If the battery indicator seems inaccurate after 3-5 charge cycles, perform the calibration once more. Avoid frequently draining to 0% — that shortens overall battery lifespan. For long-term storage (more than 3 months), keep the battery at approximately 60% charge.
