- Do these come charged and ready to use?
- No. NiMH cells like these usually arrive with little or no charge and need a full charge before first use. Charge them in a NiMH-compatible charger, not an old NiCd-only unit.
- Will they work in any device that takes AA batteries?
- They fit any standard AA slot, but each cell delivers 1.2 V instead of the 1.5 V of alkalines. Most devices tolerate that; a few voltage-sensitive items may show low-battery warnings early.
- How do they compare with eneloop batteries?
- These hold more charge per cycle at 2500 mAh, while eneloop cells keep their charge far longer in storage. Pick these for frequent heavy use, eneloop for gear that sits idle.
- How many recharge cycles should I expect?
- Ultralast does not publish a cycle rating for this model. NiMH cells generally handle hundreds of cycles, but expect capacity to fade with heavy use and fast charging.
- Can I charge them in any charger?
- Use a charger designed for NiMH AA cells. A smart charger that stops at full charge is safer than a timer-based unit, which can overcharge high-capacity cells.
- What is in the pack?
- Four AA NiMH batteries rated at 2500 mAh and 1.2 V. No charger, case or adapter is included.
