The different chemistries makes a different voltage. The alkaline is 1.5 volts and the NiCad is 1.2 when fully charged. If it will work with the lower voltage then it may only assume that the battery is low. But when the NiCad actually gets low then the device may not work properly.
They should be dropped in a battery recycling bin. Such bins often exist in or near electronics stores. Make sure they accept alkaline batteries. Some only accept rechargeable batteries. Using rechargeable batteries can save you money and greatly reduce the number of batteries you need to dispose of.
While it is possible with some, but not all NiMh chargers, it is not recommended. Charging alkaline batteries can make them leak chemicals. Only attempt this if you are experienced with electronics and are willing to deal with leaking batteries. The batteries often leak while being recharged, but sometimes they leak later in the device they power. Even if they do recharge, you will probably only get about 5 cycles. I would highly recommend that you get some NiMh batteries. They only cost about 6 times as much as alkalines, but they can be recharged hundreds of times.
Im not an expert or have full knowledge of this so don't take my word for it. But I think it's to do with the energy given from alkaline and other substances used in batteries. Maybe alkaline batteries don't give enough energy.
This is not necessarily true. Usually the brand of battery is not as important as the technology used. An alkaline battery should last longer than a regular carbon battery, no matter what the brand.
Rechargeable batteries are an excellent alternative to regular alkaline batteries. Although they may initially cost a little more than regular batteries, the money you save in the long run definitely outweighs the initial price difference.
Most things that you use on a daily basis require the use of alkaline batteries. Most stores sell alkaline batteries, but there are some places where you should be wary of purchasing the batteries at. Dollar stores and other discount locations sometimes get batteries that are left over from other stores, and they may not last as long as newer batteries.
For Alkaline batteries i recommend putting in great sunlight or buying an electrical battery charger.
Unless you want to see batteries burst, you should never charge normal alkaline batteries with any charger. Brand names don't matter much in this sense either. Only charge batteries that have the word "Rechargeable" or "NiMH" on them. Though there are some alkaline batteries that are rechargeable, a regular battery faces the risk of explosion or severe damage when charged.
Lithium batteries use some type of lithium in their construction and are different from more traditional alkaline batteries. One of the key features of lithium batteries is the increase in the amount of electricity that is produced from a certain size of battery when compared to alkaline batteries. This feature also has a drawback, however, since a lithium battery can have a very harmful reaction when short circuited inside of a device. This can actually cause the battery to discharge electricity and heat very quickly, potentially igniting the battery itself.
Depends. Because alkaline batteries do not exhibit the characteristics to be classified as a reactive or ignitable waste; and because the batteries pass the Toxicity Characteristic Leaching Procedure (TCLP) test; and because the batteries do not meet the required definitions to be a corrosive waste, alkaline batteries are not hazardous waste under Resource Conservation and Recovery Act (RCRA). (Mercury was phased out of alkaline batteries in conjunction with the "Mercury-Containing and Rechargeable Battery Management Act," passed in 1996) States can be more restrictive than the federal government, but most states classify alkaline batteries according to RCRA regulations. However, some states, have more rigorous regulations. The hazardous waste characterization requirements of Alaska, California, Minnesota, Rhode Island and Washington include a bioassay component. Additional states such as South Carolina regulates all types of batteries as special waste.
Some D batteries are made up of alkaline, zinc-carbon, lithium iron disulfide, nickel cadmium, and nickel-metal hydride.
For the most part batteries brands do not make a huge difference but there are some things to know about purchasing cheap batteries so you can ensure you get the most bang for your buck. Always check the expiration date on the package. Batteries do not hold a charge long after their expiration date. Expired batteries are most commonly found at discount retailers. Alkaline batteries last considerably longer than regular batteries so if the dates are not an issue always go Alkaline.
