GP Batteries

GP Batteries at a glance

GP Batteries offers dependable, widely compatible power across three main lines: ReCyko rechargeable NiMH batteries, primary alkaline batteries, and compact power banks. The brand focuses on everyday reliability, practical pricing, and user safety, making it a solid choice for households, offices, schools, and light professional use.

Product range and when to choose each

ReCyko rechargeable NiMH (AA/AAA and others)

• Best for: High-drain and frequently used devices (flashlights, digital cameras, game controllers, wireless mice, toys).
• What to expect: Nominal 1.2V; low self-discharge that retains most charge in storage (often ~70–85% after a year); rated for hundreds of recharges (model-dependent, commonly up to 500–1000 cycles).
• Typical capacities: AA ~1900–2700 mAh; AAA ~700–950 mAh. Higher mAh = longer runtime but slightly longer charging time.
• Choose if: You use the device weekly or daily and want lower long-term cost and less waste.
• Avoid if: The device sits unused for many months and you won’t recharge regularly (consider alkaline instead).

Primary alkaline (AA, AAA, C, D, 9V)

• Best for: Low- to moderate-drain, infrequently used devices (TV remotes, clocks, basic radios, emergency torches).
• What to expect: Nominal 1.5V; long shelf life (often up to ~7 years when stored cool and dry); no charging required.
• Choose if: You want ready-to-use power for standby or low-drain applications.
• Avoid if: The device is high-drain and used daily—rechargeables are more economical over time.

Power banks

• Best for: On-the-go charging of phones, tablets, earbuds, and other USB-powered devices.
• What to expect: Compact housings, multiple ports (often USB-A/USB-C), and safety features like overcharge and short-circuit protection. Check the output rating (e.g., 10,000–20,000 mAh capacity; 18W+ output) to match your device.
• Choose if: You need portable backup power or fast top-ups while traveling.

How to choose within GP’s lineup

• Match capacity to use: AA 2000–2300 mAh suits most devices; choose 2500–2700 mAh for camera flashes or high-output bike lights. For AAA, 800–900 mAh balances runtime and longevity.
• Cycle life vs capacity: Lower-capacity NiMH often offer more recharge cycles; high-capacity cells deliver longer runtime per charge but may have fewer total cycles.
• Voltage needs: Some devices expect 1.5V. Most electronics work fine with 1.2V NiMH, but a few battery meters or older gear may read “low.” If in doubt, test or use alkaline.
• Standby devices: Use alkaline for clocks, remotes, and alarms that sit for months. For smoke/CO alarms, follow the manufacturer’s battery type recommendation (often 9V alkaline or lithium primary).

Performance snapshots (rule-of-thumb)

• LED flashlight drawing 300 mA: AA 2000 mAh NiMH ≈ 5–6 hours per charge (brightness may step down over time).
• Game controller averaging 100 mA: AA 2000 mAh NiMH ≈ 15–18 hours per charge, depending on vibration and wireless usage.
• Wireless mouse at 20 mA average: AA 2000 mAh NiMH ≈ 3–4 days of continuous run-time, typically weeks of normal use.

Actual runtime varies by device efficiency, temperature, and age of the cells.

Charging and care tips

• Use a smart NiMH charger: Prefer models with individual bay control, delta-V or timed termination, and trickle prevention to extend battery life.
• Don’t mix: Avoid mixing different brands, capacities, or old and new cells in the same device.
• Storage: Store partly charged NiMH (~40–60%) and all batteries in a cool, dry place. Keep alkalines in packaging until use.
• Temperature: NiMH performance drops below 32°F (0°C); warm cells to room temperature before use. Avoid charging when very cold or hot.
• Recycling: Recycle end-of-life batteries at local collection points. Never dispose of batteries in fire or household trash where prohibited.

Alternatives to consider

• Lithium primary (non-rechargeable): Excellent for very cold weather and long shelf life in high-drain gear (e.g., AA lithium for winter hikes).
• Rechargeable Li-ion packs: Best for devices designed for them (cameras, power tools). Use only the specified pack and charger.

FAQ

Will 1.2V NiMH work in a device that expects 1.5V AA/AAA?

Usually yes. Many devices regulate voltage internally and run reliably on 1.2V NiMH. A few products with simple battery meters may show “low” earlier; if performance is poor, use alkaline or check the manual.

How many times can ReCyko batteries be recharged?

It depends on the model and usage. Many ReCyko cells are rated for hundreds of cycles; some lines specify up to around 500–1000 cycles under ideal conditions. Heat, high charge rates, and deep discharges reduce lifespan.

Are GP alkaline batteries leak-resistant?

Modern alkaline designs include anti-leak measures, but no alkaline is leak-proof. Remove cells from devices you won’t use for months and replace any battery that shows corrosion or swelling.

Can I charge GP alkaline batteries?

No. Never attempt to charge alkaline batteries. Use only NiMH cells with a compatible charger.

Which GP power bank should I buy?

Match capacity to your needs (e.g., 10,000 mAh for a day trip; 20,000 mAh for a weekend) and check output wattage and port type for your device (USB-C PD for newer phones/tablets). Look for safety protections and airline-compliant capacities (<100 Wh) for travel.
