Pack de pilhas recarregáveis de 9V VERICO LoopEnergy PP3 4500 — iões de lítio, 2 unidades, 500 mAh, carregamento USB-C

VERICO LoopEnergy PP3 4500 is a rechargeable 9 V Li‑Ion battery pack supplied as a 2‑piece set. Each battery delivers 500 mAh capacity and stable 9 V output, with built‑in protections for overheat, overcharge, overvoltage and short circuit. The pack charges via USB‑C for convenient recharging without a dedicated charger. The product colour combination is black and green and it is designed to replace disposable 9 V PP3 cells in portable electronics and safety devices.

Advantages

The LoopEnergy PP3 4500 offers a constant 9 V output and low self‑discharge, which ensures devices operate reliably over extended periods. USB‑C charging simplifies replenishment and removes the need for special charging stations. Lithium‑Ion chemistry provides a high number of recharge cycles compared with single‑use batteries, while integrated safety circuitry protects the cells and connected devices.

Suitable for

• Smoke detectors and carbon monoxide alarms that accept rechargeable 9 V blocks
• Wireless microphones and audio equipment requiring stable 9 V supply
• Portable measurement tools such as multimeters and sensors
• Hobby electronics, small transmitters and other portable 9 V devices

When it may not be suitable

This rechargeable 9 V pack may not be appropriate where device manufacturers explicitly prohibit rechargeable batteries or where guaranteed OEM single‑use battery performance is required. Some legacy equipment or devices with strict calibration based on primary cells may behave differently with a rechargeable Li‑Ion 9 V due to differences in internal impedance and discharge curve.

Key specifications

• Battery technology: Lithium‑Ion (Li‑Ion)
• Nominal voltage: 9 V
• Capacity per battery: 500 mAh (approx. 4500 mWh)
• Number of batteries included: 2
• Charging interface: USB‑C
• Built‑in protections: overheat, overcharge, overvoltage, short circuit
• Colour: Black and Green
• Low self‑discharge for extended shelf life

How to use

Install the rechargeable 9 V battery into the device following the device manufacturer’s polarity markings. Charge the battery using a USB‑C cable connected to a suitable USB power source; observe the device’s or battery pack’s indicator (if present) to determine charging status. For best results, charge fully before first use and avoid exposing the batteries to extreme temperatures. Follow device instructions for replacing and securing the battery to ensure proper contact and operation.

What to consider before purchase

• Check that your device accepts rechargeable 9 V (PP3) batteries and that polarity matches.
• Confirm that device performance is compatible with a rechargeable Li‑Ion discharge profile.
• Ensure you have a USB‑C charging source available for recharging the batteries.
• Consider the stated capacity (500 mAh) relative to your device’s power consumption and expected runtime.

Recommendations

Store batteries in a cool, dry place and charge them with a compliant USB‑C power source. For long storage, charge to around 40–60% and check periodically. Replace both batteries in paired devices when one shows significant capacity loss to maintain balanced operation.
