Disposable Batteries

These batteries hold more power than rechargeable batteries but must be replaced more frequently. When choosing a battery, use the capacity, measured in milliampere-hours, to compare among similar sizes. The higher the mA-hr. rating, the longer the battery should last.

Alkaline Battery—Use alkaline batteries in low-drain devices such as clocks and radios.

Lithium Battery—Lithium batteries are lightweight and long lasting. They work well in high-drain devices such as digital cameras.

Rechargeable Batteries

AAA

Battery

Reduce battery costs by powering devices with rechargeable batteries. These batteries work well in high-drain devices such as digital cameras. When choosing a battery, use the capacity, measured in milliampere-hours, to compare among similar sizes. The higher the mA-hr. rating, the longer the battery should last.

Nickel Metal Hydride (NiMH) Battery—Nickel metal hydride (NiMH) batteries last longer than nickel cadmium batteries. Recharging without completely draining first does not affect battery life.

Nickel Cadmium (NiCad) Battery—Nickel cadmium (NiCad) batteries should be drained completely before recharging for maximum battery life.

Cannot Be Sold to Canada—Chargers cannot be sold to Canada due to import regulations.

Long-Shelf-Life Rechargeable Batteries


AAA Battery	Chargers

Shipped fully charged, these batteries hold their charge even after months on a shelf. They are nickel metal hydride (NiMH), so recharging them without completely draining will not affect battery life. They work well in high-drain devices such as digital cameras.

Cannot Be Sold to Canada—Chargers cannot be sold to Canada due to import regulations.

Battery Holders with On/Off Switch

Battery holders with an on/off switch can be turned on and off without opening the enclosure, reducing the risk of damaging internal components. You can also power them on and off without desoldering the wire lead to your application when making configuration changes. Because they’re easy to turn off, these holders help preserve battery life longer than holders without an on/off switch.
