AA 1.2V 2800mAh Ni MH Rechargeable Battery (Pack of 2) OSL-201

Description

The OSL-201 AA Rechargeable Battery (2800mAh) is a high-capacity, reliable power solution designed to keep your most demanding electronics running longer. Unlike standard disposable alkaline batteries, these advanced Nickel-Metal Hydride (Ni-MH) cells provide a massive 2800mAh of energy storage and a highly stable 1.2V output. This makes them perfectly suited for high-drain applications like robotic chassis, motorized DIY projects, digital cameras, and wireless gaming controllers.

By switching to this OSL-201 rechargeable pair, you significantly lower your long-term operating costs and help reduce environmental waste. Formulated with modern Ni-MH chemistry, these batteries feature a low self-discharge rate and suffer from virtually no "memory effect," meaning you can safely recharge them hundreds of times without a drop in maximum capacity.

Frequently Asked Questions (FAQ)

Q: My device says it needs 1.5V batteries. Will these 1.2V batteries work?
A: Yes! Standard alkaline batteries start at 1.5V but their voltage steadily drops as they discharge. Ni-MH rechargeable batteries start at 1.2V but maintain that steady voltage for almost their entire discharge cycle. They are perfectly compatible with almost all devices designed for standard AA batteries.

Q: Do these batteries need to be fully empty before I charge them?
A: No. Modern Ni-MH cells like the OSL-201 do not suffer from the "memory effect" found in older battery types. You can safely top them off on your charger at any time.

Q: Can I charge these using any battery charger?
A: You must use a charger specifically designed for Ni-MH batteries. Using a charger meant exclusively for Li-ion or Ni-Cd can damage the cells and create a safety hazard.
