Recondition Old Batteries
The charger for your Li-ion battery pack will keep your tools running at peak performance. Manufacturers make smart chargers with a computer chip that reads the available charge, or history of die battery, when it's placed on the charger, and recharges it accordingly. LIGHTER TOOL. You'd think that with all this technology in the battery pack, it would weigh down the tool, but die opposite is true. ALi-ionbattery weighs about half what a NiCad battery does at the same voltage (see photo below). And with more power per ounce, you can have a higher voltage tool that weighs less. This translates to less fatigue in the shop.
In defense of Ni-Cd batteries, you can recharge them more times over a lifetime of use than today's Ni-MH batteries. Shorter run time, but more charge-ups what should you choose In the end, you'll drive about the same number of screws with either type before you wear out the battery. Used Ni-Cd batteries must be recycled, because cadmium is a hazardous waste. Under most current regulations, used Ni-MH batteries can be tossed in the trash, but we recommend that you recycle them anyway. 8 Batteries come in two types, the older, standard nickel-cadmium (Ni-Cd) and a newcomer, nickel-metal hydride (Ni-MH). Ni-MH batteries offer longer run times than Ni-Cd batteries, but take fewer charges over their life span. One-hour chargers generally contain sophisticated electronics to diagnose a battery's temperature and voltage as it's charging. Slow chargers do not. The practical difference for users is one of convenience and maximizing battery life. You can walk away and forget about a battery...
A Near-freezing temps aren't good for nickel-cadmium (NiCad) battery packs and can actually damage nickel metal hydride (NiMH) recharge-ables. However, it's exposure to higher temperatures above 80 - 85 degrees that can wreak havoc with cordless tool batteries. It tends to degrade the chemical gels and insulation materials inside the cells and significantly reduce their performance over time. Heat-damaged batteries appear to recharge as normal, but actually retain less of a charge. So cordless tool batteries should be kept in a cool spot during hot summer months. To prevent cold weather damage in the winter, move battery packs inside the house. Fortunately, you can rejuvenate NiCad battery packs that have been sitting idle for a long time by putting them back into active use. Their capacity will be restored after a few discharge and recharge cycles.
It will handle general-purpose sanding, grinding and drilling. The control is especially good on intricate projects. It has a 4.8-volt motor that runs for up to one hour on the Ni-Cad battery pack. The battery recharges in three hours in a plug-in charger. You can select from two speeds 5,000 or 10,000 RPM and the knurled collet nut can be tightened or loosened with your fingers alone. The tool accepts standard Dremel collets, bits and accessories up to a ' -in. dia. shank. (Price 39)
Hitachi's EB12BH Belt Pack Battery Holder puts the weight of your battery on your belt, not in your hand. The belt pack holds two batteries that connect to the drill with a 56-in.-long cord. Using two batteries doubles the drill's run time. Street price 90. The battery pack also comes standard with Hitachi's DS13E22B drill for about 199.
Battery technology is all about chemistry and while Li-ion batteries are built using the same basic principles as all batteries, the chemistry is a little different. The negative terminals are made of lithium ions dissolved in carbon or graphite. The positive terminals are lithium and manganese or cobalt in a lithium salt. The battery pack also includes a memory chip that stores the history of the battery (see upper photo on opposite page). By reading tins chip the charger can adequately charge it. battery packs in power tools. One of the best features of the Li-ion battery is its ability to be stored for several days in a tool case and still be fully charged when you're ready to go to work again. Smart chargers can increase battery life by monitoring the charging cycles in a battery. Rechargeable batteries have really changed over the years. First there was the nickel cadmium (NiCad) battery, then the nickel metal hydride (NiMH) battery, and now the lithium-ion (Li-ion) battery.
Walburn uses two silicon solar panels to charge a heavy-duty, deep-cycle battery, which drives a V3-HP motor on the lathe. I can work all day with this says Walburn, if I in the shade ' His sharpening wheel is mounted atop the lathe. He doesn't need dust collection the wind takes care of that. Eugene Dimitriadis
DeWalt says you'll be able to buy the drill-drivers and hammer drills with a range of battery packs including ones rated at l i.-i volts the most powerful packs available to date. The line will include both pistol-grip and T-handlc drill configurations. and tools will be li liter weight
At the heart of all PAPR systems are one or more filters, a fan and a rechargeable battery pack that powers the unit. On some systems, these com Being an experienced wearer. I had some specific ideas about what I did and didn't want to do in testing these creatures. First, I wanted to concentrate on the units that seemed most useful for woodworking, rather than looking at every conceivable system on the market. Second, 1 didn't want to get mired down in scientific lab tests that might not address real-life performance. (The chart shows the federal ratings for each unit.) Instead, I wanted to concentrate on practical issues such as weight, noise, visibility and comfort, battery life, and impact protection.
DIY Battery Repair
You can now recondition your old batteries at home and bring them back to 100 percent of their working condition. This guide will enable you to revive All NiCd batteries regardless of brand and battery volt. It will give you the required information on how to re-energize and revive your NiCd batteries through the RVD process, charging method and charging guidelines.
