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.

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.

Lithium ion (Li-Ion) batteries are lightweight and long lasting. For maximum battery life, recharge before they drain completely. Batteries with lithium iron phosphate (LiFePO4) chemistry can be recharged more than twice as many times as NiMH and NiCAD batteries. They’re more stable than other lithium batteries, reducing the risk of thermal runaway if exposed to overheating or short circuiting. Note: These batteries can only be used with LiFePO4-compatible chargers. Batteries with lithium cobalt oxide (LiCoO2) chemistry are long lasting on a single charge.

Chargers cannot be sold to Canada due to import regulations.

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.
