Which Batteries are the Best? Alkaline vs. Lithium

There are two main types of batteries which are sold in various sizes like AA, AAA, C and D: alkaline and lithium. Both are available as one-time use (disposable) and rechargeable. Some are better than others depending on what you need the battery for. Smart consumers choose depending on the task. So, which batteries are the best?
|
ALKALINE batteries are best for:
|
LITHIUM batteries are best for:
|
|
LOW DRAIN devices- devices that do not drain the battery
|
HIGH DRAIN devices- devices that utilize more power and may need battery changes frequently if using alkaline batteries
|
|
LOW USE devices- devices that are turned off most of the time
|
HIGH USE devices- devices that are turned on most of the time, if not turned on permanently
|
|
NON-CRUCIAL devices- devices that are not going to interrupt tasks or will not have memory affected if power was lost suddenly
|
CRUCIAL devices- devices that would pose a danger if power was lost suddenly; i.e. data gets lost/ damaged.

Since both alkaline and lithium are available in one-time use and rechargeable varieties, what are the PROS AND CONS of ONE-TIME USE VS. RE-CHARGEABLE?
|
ONE-TIME batteries
|
RE-CHARGEABLE batteries
|
|
PROS
|
PROS
|
|
Cost less at the register (making it an economical purchase for low drain, low use, non-crucial devices)
|
Can be used again and again (reducing need to buy replacements and reducing impact on environment)
|
|
Ready-to-use right out of the package. No charging, no wait.
|
Last longer (during use and overall lifespan, even though these lose lifespan, too, over time)
|
|
CONS
|
CONS
|
|
Can only be used once, requiring purchase of replacements
|
Cost more
|
|
Do not last as long as rechargeable (during use and overall lifespan)
|
Must be charged before use (including first use). Overcharging is common. This damages the battery, resulting in a shorter life span during use and overall.
