The Rechargeable Batteries
Borek says that rechargeable batteries are a growing part of his business as eco-conscious Austinites try to avoid waste and go green.Unlike regular batteries, though, rechargeables — including speciality ones in devices like cordless phones and some video-game controllers — require maintenance for Sony-VGP-BPS2. It’s always best, Borek says, to let rechargeables run down all the way and then charge them back up. Rechargeables have a memory that can be scrambled by overcharging or by cutting short the discharge cycle.
If you leave a cordless phone on a cradle charging all the time, “you’ve trained that battery to be bad,” Borek says. “What batteries need are cycles. They’re like your heart. They need exercise and rest every day for Dell C1295 battery .”Rechargeables can be retrained by wearing them down until they’re drained and then recharging, but there are also “smart rechargers” that can discharge and charge batteries until they’re like new and that won’t overcharge a battery.
Over the past five years, as digital camera adoption has exploded, chargers have been introduced that can juice up batteries in as little as 15 minutes. Charging at this high speed for Dell KD476 battery ,, however, can shorten the life of recycleables, just like overcharging can.Serge Traylor, a brand manager at Energizer Holdings Inc., says you get what you pay for when it comes to rechargers. “The low-end chargers, typically, you have to manage more on your own. More expensive battery chargers have all that built in.”
Borek explains that when buying rechargeables, it’s best to look at the milliamp hours (mAh). While traditional battery power is measured in volts, rechargeables are measured in this unit, which tells you how much power they can store on a single charge for HP F4809A battery . “The higher the milliamps, the more gasoline it has in its tank,” Borek explained.
Chargers start at about $10-$20 and go up past $50 for tricked-out units with LCD displays that can charge eight or 10 batteries at a time (often with batteries included). Who uses them? Everyone from real-estate agents using digital cameras to hobbyists who power radio-controlled cars and model helicopters.
Borek says that the biggest enemy to battery life is disuse.In motorcycles and boats that are only used seasonally or in camcorders that only come out during the holidays for C1295 battery , a sitting battery may expire long before its time.”This time of year, we’re selling camcorder batteries like you wouldn’t believe,” Borek said. “It sits in a bag all year, never used. Batteries just laying around never used tend to go bad.”
For camcorders and cordless drills, he suggests power-draining and recharging the devices once a month to keep them fresh.For motorcycles and boats, devices called battery tenders can cycle a battery, topping off the energy without overcharging and preventing the battery from going bad. With a tender for KD476,, a boat or motorcycle battery can last two or three years.”If you don’t use anything, that battery will be dead inside of 13 to 14 months,” Borek said.With our suffocating Texas summers, car batteries last three or four years, Borek said, until they finally succumb to heat and vibration.
