Gama Sonic 3.2 V 1,500 mAh LiFePO₄ (with male adapter)

Overview

The Gama Sonic 3.2 V, 1,500 mAh LiFePO4 battery with a male adapter is a plug-in replacement for select Gama Sonic solar lights that require a 3.2 V lithium iron phosphate pack with a male connector. It provides consistent nightly runtime, strong cycle life, and easy, no-solder installation.

Who Should Choose This

• Use if your fixture's manual specifies a 3.2 V LiFePO4 battery and a male plug connector.
• Use when you want simple, tool-free replacement and dependable performance in outdoor solar lighting.
• Avoid if your light uses 3.7 V Li-ion, NiMH AA/AAA cells, sealed lead-acid, or a different connector type.

Key Specs

• Voltage: 3.2 V (LiFePO4 chemistry)
• Capacity: 1,500 mAh
• Connector: Integrated male adapter (plug-in)
• Intended use: Select Gama Sonic solar fixtures that specify 3.2 V LiFePO4 with a male plug

Runtime Expectations

Runtime depends on your light's current draw and brightness setting. As a quick estimate:

• Estimated hours per charge ≈ 1,500 mAh ÷ device draw (mA).
• Example: A light drawing 75 mA can run about 20 hours (1,500 ÷ 75).

Cold temperatures and cloudy days can reduce nightly runtime. Using lower brightness modes typically extends runtime.

Compatibility Checklist

• Voltage matches: 3.2 V only (LiFePO4). Do not substitute 3.7 V batteries.
• Connector matches: male plug fits the fixture’s female socket.
• Space fits: confirm the battery’s physical format matches your fixture’s battery bay.
• Chemistry matches: use LiFePO4-only chargers/circuits (most solar fixtures with LiFePO4 already comply).

Installation

1. Turn the light OFF and, if possible, disconnect the solar panel.
2. Open the battery compartment and remove the old battery by unplugging it.
3. Align and insert the new male plug into the fixture’s female connector—do not force it.
4. Secure the battery in the compartment and close the cover.
5. Turn the light ON and allow a full day of sun for the first charge.

Care and Maintenance

• Keep connectors clean and dry; wipe dust or oxidation gently with a dry cloth.
• If storing more than 1–2 months, charge the battery first and top up every 3–6 months.
• Avoid extreme heat; store in a cool, dry place.

Charging Guidance

• Let the solar fixture charge the battery under direct sunlight.
• If bench-charging, use a LiFePO4-specific charger set for 3.2 V cells (max 3.65 V CV) and a conservative current ≤0.5C (≤0.75 A).
• Do not use chargers intended for Li-ion (3.7 V) or NiMH.

Safety Notes

• Do not short-circuit, puncture, or disassemble.
• Do not mix old and new batteries in the same fixture.
• Do not run in series/parallel unless the fixture specifically supports it.
• Recycle at a certified battery collection point; do not dispose in household trash.

Alternatives

• If you need longer runtime, look for a higher mAh 3.2 V LiFePO4 with the same connector and form factor recommended by your fixture.
• If your fixture specifies a different voltage or chemistry, select a battery that exactly matches those requirements.

FAQ

How do I confirm this fits my light?

Check your fixture’s manual or the label inside the battery compartment. It should list 3.2 V LiFePO4 and show a matching male plug. If uncertain, compare the connector visually before purchase.

Will this make my light brighter?

Capacity affects runtime, not brightness. Brightness is controlled by the light’s LEDs and driver. A properly matched 1,500 mAh battery helps sustain brightness for longer periods.

How long does it take to charge?

Most solar fixtures need 6–10 hours of strong sun for a full charge. Cloud cover, panel size, and season can extend this time.

Can I use my old Li-ion or NiMH charger?

No. Use only LiFePO4-compatible charging (the solar fixture typically provides this). Other chemistries’ chargers can damage the battery.

What should I do with the old battery?

Recycle it at an authorized battery drop-off location. Many hardware stores and municipal programs accept rechargeable batteries.
