What type of battery should I use?

The most commonly used battery of all is an alkaline battery (meaning it contains an alkaline electrolyte, usually potassium hydroxide). Best use: "Low-drain" devices such as LED headlamps, LED flashlights, toys, remote control devices, clocks and radios, and even moderate-drain items such as lights using incandescent bulbs.

How long does a lithium battery last?

Estimated shelf life (at 68°F/20°C): 5-7 years. Lithium, an exceptionally light metal, gives lithium batteries the highest energy density of any battery cell. Thus, they can store more energy than alkaline batteries or any single-use battery of a comparable size. And they are superb performers in extreme temperatures, both hot and cold.

Are Li-ion batteries recyclable?

Recyclable. Cons: More expensive. Even if left unused, is negatively impacted by age. Volts: 3.6 (with some variations). Estimated number of recharging cycles: 500-1,000+. Self-discharge rate: Very low, but age is the enemy of Li-ion batteries. Even if unused, the simple passage of time robs them of some energy capacity.

How do you store a lithium ion?

Storage: Store at roughly 60°F/15.5°C, either fully charged or at 50 percent of capacity (opinions vary on this topic). Tips: Recharge often, even if only a modest amount of energy has been drained. Avoid fully exhausting a Li-ion before recharging. Doing so won't ruin a Li-ion, but it is not viewed as a recommended practice.
