About Battery Disposal

AAA with Button Top

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.

Use alkaline and carbon zinc batteries in low-drain devices such as clocks and radios.

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

Rechargeable Batteries

AAA with Button Top

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) batteries last longer than nickel cadmium batteries. Recharging without completely draining first does not affect battery life.

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

Chargers cannot be sold to Canada due to import regulations.

Long Shelf-Life Rechargeable Batteries

AAA with Button Top

Charger for NiMH Batteries

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.

Chargers cannot be sold to Canada due to import regulations.

Enclosed Battery Holders

Holders have snap-on or screw-on covers to fully enclose and protect batteries.

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.

Holders with a PCB (printed circuit board) connector can be easily joined to a circuit board without soldering. They require a female printed circuit board connector (sold separately). Mount the female connector on a circuit board to serve as the receiving end for these holders.
