Purchase the right type of rechargeable battery for your device.
Not all rechargeable batteries are created equal. Wonder why some are so much more expensive than others? There are factors other than just the name brand to look at when searching for the "best" rechargeable battery. If your digital camera dies only after a few hours of use, it could be the type of rechargeable batteries you are using.
Instructions
1. Review the latest technology before purchasing a rechargeable battery. In July 2011, Consumer Search rated the hybrid Nickel-Metal Hydride (Ni-MH) cell batteries the best among the best for high-draining rechargeable devices, such as digital cameras and gaming remote controls. Ni-MH batteries come charged, so there is no waiting to charge them after buying. Ni-MH batteries also hold their charge well during use, and for an extended period of time while being stored away. Technology changes rapidly, however, and next year the Ni-MH might be old news; for right now, however, they're considered the "best."
2. Review each battery's mAh rating. A battery's mAh stands for milliampere-hour, and indicates the battery's energy storage capacity -- the higher the rating, the better it can handle constant high-drain devices. As of the date of this publication, high-capacity Ni-MH batteries can have up to 2900 mAh. An mAh of 2850 or 2700 is also very good. This is where price differences play a factor in determining the best battery for your needs, so be sure that you are comparing the same mAh rating when comparing different batteries.
3. Calculate your device usage. Think about the device you are buying the rechargeable battery for, and how many hours per day you plan on using it. Take the knowledge that you have gained about Ni-MH batteries and their mAh ratings and determine how much power your battery is going to need. If you are purchasing a battery for your digital camera before your vacation, a higher mAh will give your camera longer life; purchasing rechargeable batteries for your son's game controller ... and want an excuse to have him stop playing after a certain amount of time? Purchase lower mAh batteries that need to be charged more frequently.
4. Purchase your rechargeable battery from your favorite electronics store or online. As discussed, compare prices based on your individual device needs and find your best price from a reputable manufacturer.
