Powerex Precharged AA 2600 mAh (4-pack)

Overview

Powerex Precharged AA 2600 mAh batteries combine high capacity with low self-discharge (LSD) chemistry. They arrive charged, hold power in storage, and deliver steady output for demanding gear like speedlights and audio recorders, as well as everyday devices such as remotes, toys, and game controllers. Use them to cut waste, reduce last‑minute battery runs, and standardize on a reliable AA system.

When to Choose These

• Use if you want maximum runtime per charge in AA devices (e.g., camera flashes, headlamps, microphones, controllers).
• Use if your batteries sit in a drawer or bag between uses; LSD chemistry stays ready for months.
• Avoid if you require multi‑year shelf life without recharging (choose primary lithium AA for emergency kits).
• Avoid if a device strictly requires 1.5 V alkalines and shows early low‑battery warnings with 1.2 V NiMH (check the manual).

Quick Specs

Estimated Runtime Examples

Actual runtime varies by device, power setting, and temperature. Typical expectations:

• Speedlights: about 150–300 full‑power pops; faster recycle at lower power levels.
• Headlamps: 4–8 hours at 200–400 lumens (roughly 300–600 mA draw).
• Game controllers: about 20–40 hours of play, depending on vibration and wireless usage.
• Wireless mouse/keyboard: weeks to months between charges with normal office use.
• Portable audio recorders/transmitters: a full session or event on one set; bring a spare for long days.

Charge Time Guide

Use a smart NiMH charger with independent slots. Typical per‑cell charge times for 2600 mAh:

• 1000 mA: ~3–4 hours
• 500 mA: ~6–7 hours
• 200 mA (overnight): ~14–16 hours

Times include top‑off; actual durations depend on charger and cell condition.

Charging Best Practices

• Choose a charger that supports NiMH, has independent channels, and terminates on -ΔV or equivalent smart control.
• Let cells cool after heavy use; avoid charging or storing while hot.
• Remove cells when full; avoid leaving them on trickle for days.
• Label sets used in pairs/quads so they age together (e.g., Set A, Set B).
• Top off before important jobs if the set has been idle for weeks.

Care and Storage

• Store at room temperature; avoid hot cars and freezing environments.
• Partial charge is fine for storage; recharge before critical use.
• Keep terminals covered in cases to prevent shorting.
• Retire and recycle any cell that is leaking, swollen, or physically damaged.

Pros and Cons

• Pros: High 2600 mAh capacity, low self-discharge, stable voltage under load, hundreds of cycles, lower cost and waste vs disposables.
• Cons: Heavier than alkaline; nominal 1.2 V may trigger early low‑battery indicators in a few devices; reduced performance in extreme cold; requires a compatible charger and routine charging.

Compatibility and Alternatives

• Compatible with NiMH/NiCd smart chargers. Do not use Li‑ion–only chargers.
• Works in most devices designed for AA alkaline; voltage is 1.2 V vs 1.5 V alkaline, but output is stable under load.
• Need multi‑year, no‑maintenance storage? Consider primary lithium AA (non‑rechargeable).
• Need regulated 1.5 V output from rechargeables? Some USB‑rechargeable 1.5 V AAs exist; check device compatibility and charging requirements.

Safety Notes

• Insert with correct polarity and charge only in NiMH‑compatible chargers.
• Do not attempt to recharge alkaline or primary lithium cells.
• Do not mix old and new cells in series devices; use matched sets.
• Keep out of reach of children; avoid loose cells contacting metal objects.
