Restore the classic vertical handheld experience with this 4000mAh Li-ion Polymer replacement battery for the Anbernic RG351V. The RG351V is distinguished by its Game Boy-style vertical form factor, featuring a 3.5-inch IPS screen (640×480 resolution) and a Rockchip RK3326 chipset. This battery matches the original cell’s dimensions — critical because the RG351V’s vertical shell has specific internal tolerances that differ from horizontal models like the RG351P or RG351M. Generic batteries often have slightly thicker cells or incorrect cable routing, preventing the backplate from closing flush.
Technical Details for RG351V Owners: The RG351V runs the same RK3326 processor as other RG351 devices but in a vertical orientation with a built-in 3.5mm jack and dual microSD card slots. This 4000mAh replacement battery for Anbernic RG351V maintains the original 4.2V charge termination voltage and uses low‑resistance cells to ensure stable power delivery during emulation. For Anbernic RG351V battery replacement, the built-in protection circuit module (PCM) guards against over‑charge, over‑discharge, short circuit, and over‑current. CE, RoHS, and UN38.3 certified. To maximize Anbernic RG351V battery life, avoid frequently draining the battery below 10% — lithium-ion cells prefer partial discharges.
Step‑by‑Step Installation Guide: 1) Power off the device and remove the six small Phillips screws on the back (use a PH00 screwdriver). 2) Gently separate the backplate starting from the bottom — the RG351V vertical shell uses plastic clips along the sides, so pry carefully with a plastic spudger. 3) The battery is located in the lower half of the vertical body. 4) Use a plastic spudger to lift the original battery (it is lightly adhered). 5) Disconnect the old battery’s connector by pulling the plug (not the wires). 6) Connect the new battery — the small 2‑pin connector is keyed and only fits one way; do not force it. 7) Place the new battery in the compartment, ensuring no wires are pinched, then reassemble. 8) If the device doesn’t power on after battery replacement, leave it connected to a 5V/2A charger for 10‑15 minutes to activate the protection circuit.
Compatibility Note: Fits Anbernic RG351V only — not compatible with RG351P, RG351M, RG350 series, or RG353 series. The RG351V is the only vertical variant in the RG351 family, identified by its Game Boy-style button layout and 3.5-inch square-ish screen. If your RG351V shuts down unexpectedly when the battery indicator still shows charge, or if it drains too quickly during Game Boy, SNES, or PS1 gaming, this 4000mAh replacement battery for Anbernic RG351V will restore stable power delivery. Before ordering, please open the back panel to confirm your battery’s connector type and cable routing.
Battery Care for Vertical Handhelds: For maximum lifespan, keep battery level between 20% and 80% for daily use. Do not use Quick Charge (QC) or Power Delivery (PD) fast chargers — only use a standard 5V/2A charger. The RG351V’s charging circuit is not designed for fast charging protocols. If storing the device for more than 2 months, keep the battery at approximately 60% charge. Avoid leaving the RG351V in hot environments (e.g., inside a car in summer). Stop using immediately if the battery shows any swelling. For optimal RG351V battery health, perform a full discharge-recharge cycle (drain until auto-shutoff, then charge uninterrupted to 100%) after installing a new battery.
