Because they can be recycle constantly , you do n’t have to knock off money buy a ton of batteries . They ’re also good for the environment — you’re buying fewer batteries and shorten waste in the process .
What We Researched
We explore the best rechargeable batteries and appear at factors such as thenumber of battery in a pack , charge oscillation and lifespans , capacity rating , and price per battery . We also require Burton Kelso , a consumer and business tech expert and cybersecurity keynote speaker , to explain authoritative term you should know when buy batteries , plus tips for shoppers .
Our Top Picks
Battery Types
Rechargeable batteries come in three types : NiCd ( nickel - cadmium ) , NiMH ( nickel - metal hydride ) , and Li - ion ( lithium ion ) . Of the three , Li - ion batteries are typically the longest - lasting . While NiCd and NiMH batteries can usually last for two to five years , Li - ion batteries have an average ledge life of five year .
Li - ion batteries have the longest runtime per charge thanks to their high zip density , which is of import when using rechargeable batteries often . NiCd electric battery have the lowest runtime , but while NiMH battery have higher energy density than NiCd , they ’re also more likely to have weak cells that stop holding their charge . If you rely on the same set of battery for consistent utilization , NiMH and Li - ion batteries are the best options since they can be recharged before eat up totally without affecting their capacity . Li - ion battery also reserve their charge the longest between exercise , but they do n’t execute as well in cold temperature as NiCd and NiMH batteries .
It ’s also important to consider refuge : Li - ion batteries have the highest risk of thermal fleer , which can induce a fire risk . NiCd batteries are the safe choice to prevent thermic shoo-in ( and they ’re the best option for the environment , as well ) . Overall , Li - ion batteries do best in terms of runtime and charge capabilities , but NiMH and NiCd barrage fire are beneficial when it comes to safety .

Battery Capacity
Battery capacity refers to how much electric rush a battery can hold and limit how long the battery runs . It is valuate in mAh ( milliamp per hour ) . “ The high the capacity of the battery , the more energy it will be able to turn in to your devices , ” Kelso says . You ’ll find this number on the battery ’s label .
Rechargeable stamp battery are best for mid- to high - drain gimmick such as remote - hold in toys , wireless devices , radios , power cock , and gambling controller .
You might notice that alkaline barrage often have a higher mAh compare to rechargeable batteries , but this does n’t mean they have longer run time , as they can only deliver a portion of their capacity at a time .

Charge Cycles and Lifespans
“ A direction cycles/second is a rasping estimate of how many times a battery can go from no charge to fully charged , ” Kelso says . While you ’ll often see these listed on the computer software when you buy batteries , Kelso notes that the number is not hard and firm , especially study that everyday users wo n’t always wait until the assault and battery is fully drain to reup the bursting charge .
“ Most batteries have on average 500 charge cycles , but some can last up to 900 - 1000 bang oscillation . This is establish on the temperature [ at which ] thebatteries are storedand the means they are used , ” Kelso explains . “ Colder environment will fire a battery quicker which will result in more charge cycle . Hotter climates will stress the bombardment which will result in a shorter life anticipation . It ’s good to use and store battery in temperatures no high-pitched than 70 ℉ . ”
Best AA
