Eneloop Battery charger Kits

Panasonic Eneloop Battery Charger Kits

Eneloop kits bundle low self-discharge NiMH batteries with smart chargers that charge each slot independently. They are a reliable, reusable alternative to disposable batteries for AA/AAA devices at home or on the job.

What you get

• AA/AAA Eneloop batteries (standard or Pro)
• Smart charger (e.g., BQ‑CC17 for gentle charging or BQ‑CC55 for faster charging)
• LED status and automatic shutoff to prevent overcharge

How to choose your kit

Batteries

• Eneloop (everyday use): AA 2000 mAh (min 1900), AAA 800 mAh (min 750), up to 2100 recharge cycles. Best for remotes, toys, keyboards/mice, headlamps, and emergency lights.
• Eneloop Pro (high-drain): AA 2550 mAh (min 2450), AAA 950 mAh (min 900), up to 500 cycles. Best for camera flashes, gaming controllers, high-output flashlights, and audio gear.

Chargers

Model	Charge current (AA/AAA)	Typical time (2× AA)	Typical time (4× AA)	Highlights	Best for
BQ‑CC17	~300 mA / ~150 mA	~6–7 h	~7–9 h	Gentle charge, independent bays, LED status	Max battery life, overnight charging
BQ‑CC55	AA: up to 1000 mA (1–2 cells), 500 mA (3–4); AAA: up to 400/300 mA	~1.5–2 h	~3.5–4 h	Fast charge, per‑slot LEDs (red/yellow/green), auto shutoff	Quick turnaround, frequent use
USB‑input models (e.g., BQ‑CC87)	Varies with USB source (5 V/2 A recommended)	~2.5–4 h	~4–6 h	USB power, travel‑friendly, per‑slot control	Travel, charging from power banks

Quick recommendations

• Choose Eneloop (standard) for most devices you use daily or occasionally.
• Choose Eneloop Pro for high‑drain devices or cold weather use; expect fewer total cycles but longer runtime per charge.
• Pick BQ‑CC17 if maximizing long‑term battery health matters; pick BQ‑CC55 if you need fast turnarounds.

Real‑world runtime examples (estimates)

• Game controller (80–150 mA): Eneloop AA ~12–20 hours; Eneloop Pro AA ~15–25 hours.
• LED flashlight at 1 A on AA: Eneloop AA ~1.5–2 hours; Eneloop Pro AA ~2–2.5 hours.
• Wireless mouse/keyboard: weeks to months per charge (usage dependent).
• Emergency flashlight kept in a drawer: ready after months thanks to low self‑discharge.

Actual runtimes vary with device draw, temperature, and age of the cells.

Use if / Avoid if

• Use if you want reusable power for AA/AAA devices, quick charger feedback, and dependable cold‑weather performance.
• Avoid if a device explicitly requires primary (non‑rechargeable) batteries—common for some smoke alarms, medical devices, or sensors that require 1.5 V primaries. Check the device manual.

Setup in 5 steps

1. Insert AA/AAA NiMH cells into the charger, matching polarity.
2. Plug in (AC or USB as applicable). LEDs indicate charge state by slot.
3. Allow full charge. Typical times are in the table above.
4. Remove and install in your device. For devices using pairs, keep cells as a set.
5. Label sets (e.g., A/B/C) to rotate evenly and maximize lifespan.

Care, safety, and longevity tips

• Only charge NiMH batteries. Never attempt to charge alkaline, lithium primary, or damaged cells.
• Charge at room temperature on a hard, nonflammable surface; keep vents unobstructed.
• Do not mix capacities or old/new cells in the same device; replace and cycle sets together.
• Store at 20–25°C (68–77°F) in a dry place; top up every 6–12 months if stored long‑term.
• Gentle charging (e.g., BQ‑CC17) can extend overall cycle life; fast charging prioritizes time.
• Recycle end‑of‑life NiMH cells at an approved collection point.

Compatibility notes

• Nominal voltage is 1.2 V vs. 1.5 V for alkaline; most electronics work fine, but a few devices may show “low battery” earlier.
• AA‑to‑C/D spacers let you use AA cells in larger battery compartments for low‑to‑moderate drain devices.
• Chargers listed support AA/AAA only.

Specs at a glance

• Eneloop AA: 2000 mAh typical (min 1900), up to 2100 cycles; AAA: 800 mAh typical (min 750).
• Eneloop Pro AA: 2550 mAh typical (min 2450), up to 500 cycles; Pro AAA: 950 mAh typical (min 900).
• Low self‑discharge: Eneloop retains charge for long storage; Pro prioritizes high capacity with higher self‑discharge.
• Operating range commonly −4°F to 122°F (−20°C to 50°C).

FAQ

Which Eneloop should I use for a camera flash?

Use Eneloop Pro for faster recycle times and longer shooting between charges. If you shoot occasionally and want maximum total cycle life, standard Eneloop is sufficient.

Can I leave batteries in the charger?

Smart chargers stop charging when full, but it’s best to remove cells within a few hours of completion. Avoid storing batteries in the charger long‑term.

Can I mix different capacities or brands?

Avoid mixing in the same device. For devices that use two or more cells in series, use matched cells of the same type and age, and keep them as a set.

Do Eneloop batteries work in devices that expect 1.5 V?

Most devices work fine with 1.2 V NiMH under load. A few may indicate low battery earlier; check your device manual.

Are these good for emergency kits?

Yes. Low self‑discharge means they stay ready for months. Top them up every 6–12 months for best results.
