VSR stands for variable speed reversible. These drills come in both corded and cordless versions as will most all the drills we discuss from here on out. The drill speed is varied by the amount of pressure applied to the trigger. The farther the trigger is pulled, the higher the RPM will be. There is also a switch, usually near the trigger which reverses the operation of the drill. As you can imagine, these have distinct advantages over the basic corded drill. In addition to being able to perform all the functions of the basic corded drill, they also have a better suited although still limited ability to drive screws, and small lag bolts. Since the speed is variable, you have the ability to drill into harder material without overheating the bit. lithium ion batterty stocks First on my small list may be the Coda electric car available with a 4 seats capacity and powered by a 728 cell lithium-ion phosphate battery. The vehicle includes a range of 90-120 miles and can achieve a maximum speed of 80 mph. It comes with an interesting warranty: 3 years or 36,000 miles. An interesting fact is the battery which equips this car is covered for 8 years/100,000 miles. If you are interested in buying this electric vehicle you should know that the prices are around $37,000. cobalt ontario canada Li-ion batteries have a low self discharge rate as well, that means the battery stays charged longer when you're not using it.I also have a Milwaukee Sawzall with Li-ion batteries. For some jobs I'll be using it all day, and put it to charge at night. But a lot of time I'm just using it for the odd cut here and there, and I just don't bother charging it. It never discharges itself, I don't think that saw battery has ever been flat, but I only ever charge it for the big jobs. By changing to a hybrid vehicle, it will help erase some of your gasoline bill while helping the environment. If you spend $300 to $400 a month (or more) on fuel, multiply $400 a month times 12 months, that's $4800 a year on fuel. It would take several years to pay off the Volt. By that time, the car may be shot. You won't erase your entire gasoline bill - because you use both battery and gasoline - but it will help reduce it. I think purchasing a hybrid is a good thing but it's too long for a payback. I know the technology is available but the ROI, return on investment, is not there. If you spend $40,000 to $50,000 you may not be able to get that back within 5 years or longer. A powerful 18 volt Lithium-Ion battery supplies sufficient power to produce 1,280 in./ft. torque which can handle the toughest of jobs for a hand-held tool, but will not be so powerful that it is dangerous to use. In addition, this battery provides a much longer run time, a slower self-discharge, and a super fast re-charge time of only 15 minutes. The charger also has an embedded memory chip which allows continuous communication between the charger and the battery for the most efficient possible charge. Plus, a built-in fan provides cooling for the battery which helps prolong the battery's life. Now some may be too scared to gamble money that's easily understandable , so how would we fight back? Last year in late November a News report of Fox came up about car owner's running their vehicles on water now. A company called Water4gas invented a way to use your car battery to turn your tap water into HHO ( 2 hydrogen 1 oxygen ) gas which runs 40% longer than gasoline and is safe. lithium cobalt mining The basic rule of getting a replacement battery is that it should have the same voltage as the original. An 18V drill cannot run on a 12V battery. It can only run on a 18V battery. The other thing is that the physical packaging of a battery can be different from company to company. A 12V Ryobi battery may not fit into a 12V Makita cordless drill unless the battery has the right physical dimensions. So make sure the replacement battery looks the same as the old one before you order it. Also, if li ion stock are looking for a replacement battery of the same voltage rating and by the same company, know that battery technology is changing rapidly. An 18V lithium-ion battery has a different physical packaging than a NiCad 18V battery. The Super Soaker Thunderstorm is splash proof and constructed from durable plastic. A common fear about battery operated water guns is water leaking into the battery compartment. The battery compartment is completely enclosed and has a rubber seal that works well to keep water out. We've put plenty of water rounds through the Thunderstorm without any leakage issues.
