Battery Akyga AKY0580 mobile phone spare part, Li-Ion, 50×80×8 mm, Silver

Akyga AKY0580 replacement battery is a lithium-based rechargeable cell designed for mobile devices that accept a 50×80×8 mm pack. The unit provides a nominal voltage of 3.7 V and a rated capacity of 4000 mAh, delivered in a silver housing. The pack uses lithium‑polymer (Li‑Po) chemistry with an integrated protection circuit module (PCM) and is supplied with a 2‑pin 2.54 mm JST connector and three 150 mm leads for connection. The battery is offered as a single removable spare part for compatible devices.

Advantages

The built-in PCM protection helps prevent overcharge, overdischarge and short circuits, supporting safer operation during charging and discharging cycles. A 4000 mAh nominal capacity provides extended runtime compared with smaller cells of the same voltage. Compact dimensions (50×80×8 mm) and a standard 2‑pin JST connector simplify installation in devices designed for this form factor. The pack is accompanied by compliance documentation such as MSDS, CE and RoHS.

Suitable for

• Replacement power pack for mobile devices and handheld electronics requiring a 50×80×8 mm Li‑Po battery
• Service and repair of compatible phones, portable modules or custom devices using a 2‑pin 2.54 mm JST connector
• Applications where a 3.7 V nominal voltage and 4000 mAh capacity are required

How to use

Before installation, ensure the replacement battery matches the original pack dimensions, connector type and electrical specifications of the target device. Power the device off and, if possible, discharge residual voltage according to the device manufacturer’s service instructions. Connect the 2‑pin JST connector to the device socket or solder the leads as required by the device design, taking care to observe correct polarity. Reassemble the device and charge the new battery using the device’s standard charging method until the full charge is indicated.

Recommendations

Use only chargers and charging circuits compatible with single‑cell 3.7 V Li‑Po batteries. Store and operate the battery within manufacturer‑recommended temperature ranges, avoid physical damage, and do not short the leads. Dispose of or recycle the battery in accordance with local regulations and applicable directives (CE/RoHS). If the battery shows swelling, excessive heat, leaking, or other damage, discontinue use and replace it.
