How To Put A Charge Into Your Battery Savings-瀬名アスカ

.puters-and-Technology CopperTop and Energizer Bunny are marketing terms most Americans are familiar with, but they don’t necessarily represent the brands of batteries consumers should be buying. It’s not that Duracell or Energizer batteries are bad; it’s just that cheaper, lesser-known brands perform about the same, at least for traditional disposable alkaline laptop batteries , according to recent testing by the Worcester Polytechnic Institute for a report at DealNews… The report found "no measurable difference in quality among these batteries." In the testing, brand-name batteries were tested alongside generics and a cheaper brand, Rayovac. Those findings echo other studies, including one by Consumer Reports, which found so little difference among alkaline batteries that it re.mended cheap Kirkland Signature brand batteries sold at Costco. Online retailer Zbattery.. also did its own tests and found less than 20 percent difference among brands of alkalines, while price differences are often much greater than 20 percent, said owner Jim DeWitt. To be fair, big-name laptop battery -makers manufacture some excellent, albeit expensive, high-capacity, long-lasting batteries, such as lithium batteries. But that only highlights the growing .plexity of buying batteries, especially when you add the topic of rechargeable batteries. The myriad choices mean you might be overspending or purchasing the wrong type of batteries for your needs. Here’s what you need to know. Don’t buy heavy-duty batteries. If ever a product was misnamed, it’s heavy-duty batteries, which are just about the lightest-duty, lowest-capacity batteries you can buy HP Pavilion dv9000 Battery . They have a fraction of the capacity of alkalines but don’t cost much less. "I see no use for heavy-duty batteries for the average consumer — zero," DeWitt said. Sometimes, manufacturers that include batteries with their products — for a remote control, for example — might use the short-life batteries to cut costs, he said. Disposable akalines simply work. Quality of single-use alkaline batteries is similar among brands, so shop by price. A notable exception is the Energizer Max Alkaline, which was a poor-performing battery in Consumer Reports tests reported in December. Alkalines have a long shelf life, usually more than five years, making them ideal for seldom-used devices such as flashlights and smoke detectors. They’re also best for low-draw devices like wall clocks. "There are definitely times when you want to stick with regular alkaline HP Pavilion dv8000 Battery ," said Christine Frietchen of ConsumerSearch.., which .piles and summarizes other reviews. Buy akalines in bulk. In small quantities, a good price on standard alkalines would be 50 cents each for standard AA cells. But you can pay near half that if you’re willing to buy in bulk. You’re not taking a huge risk of batteries going dead before you use them, because alkalines have such a long shelf life. Best storage is a cool, dry place, but not a refrigerator or freezer, according to manufacturers. A recent offer found via DealNews.. was for a 24-pack of Duracell Procell AA Dell Inspiron 1545 Battery for about $8 from Amazon… That’s just 33 cents per battery, excluding shipping cost. Zbattery.. sells a case of 98 Sony AA batteries for $25.95, or 26 cents each before shipping costs. And keep an eye out for manufacturer coupons. Stacking a sale and a coupon might mean you get name-brand batteries cheaper than generics. Rechargeables can be a very good option. Besides being an environmentally appealing option, creating less battery waste, rechargeable batteries can make great financial sense. They are more expensive upfront, perhaps $2 to $4 each, but they can be recharged hundreds of times. Dell Inspiron 1420 Battery for dell inspiron 1420 laptop. With some AA batteries costing 50 cents to $1 each, rechargeables pay for themselves in just a few charges. Rechargeables can be especially good for cameras, DeWitt said. "Rechargeables in most cameras actually perform better because they deliver more current," he said. "Some cameras just don’t do well with alkalines, even the high-capacity ones." You will also need a HP Pavilion dv5 battery charger, sometimes sold as a package with rechargeable batteries. Rechargeable batteries should be recycled.
