Cordless drills provide many benefits over normal drills. There is no need for that big pile of mangled wires in the back of your truck. They are flexible, portable, and are the new industry standard. They used to be very expensive, but today everything is wireless so it is a must if you are a carpenter or handyman.
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 you 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 Volt also brings something new to the table in that it is a sporty vehicle. The styling of the Prius is not exactly lithium ion stocks cutting edge however the Volt takes it up a notch. With a sleek body and 21-inch wheels, it is sure to spice up the hybrid market.
Batteries - Many of the battery products found at the dollar stores are made with carbon zinc, as opposed to lithium, so they do not last as long. Carbon zinc can also leak, thus doing damage to your electronics.
Avoid buying spares: Unlike wine and cheese, Li batteries do not improve with age. Avoid the temptation to buy spares, unless you use them frequently. Check the manufacture date, and never buy an old Lithium battery stocks, even if on sale.
ONickel Metal Hydride (NiMh) - Popular battery about 1-2 years ago. They are lighter than Nickel Cadmium batteries, but heavier than Lithium mines Ontario batteries. These should be cycled once in a while for optimum performance.
Memory effect will reduce the life of a battery. Modern Lithium-ion batteries do not suffer from memory effect, although it does occur in Nickel-Metal Hydride (NiMH) units when charged from levels other than 0% of battery capacity. If the (NiMH) unit was fully charged when initially at say 20% capacity, the resulting available capacity would only be 80% of the factory original. Of course every time you charged the battery, the total available capacity would reduce and eventually your mobile phone would prove to be increasingly useless. Nearly all new electronic devices are now powered by Lithium batteries. You should always condition your (NiMH) battery from new.
Step 4 - Connect in the newly bought battery to the board of the iPod (where you unconnected the old battery) and set it on the glue that remained on the hard drive. Make sure that the battery and the wires are set properly so you can actually close the iPod. Snap the cover back together, you'll hear it when it's finished!
