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.
Store the nickel and lithium based rechargeable battery at about half their charge. Storing them at full charge will drastically shorten their life. It depends on the specific battery type, but in general about half charged or 40% charged is good. Also, don't store lithium-ion battery that have no charge.

A lot of radio-control fliers quickly grasp the meaning of most of the battery-associated acronyms but one: the C rating. In fact many experts cobalt mining copyright have tripped over themselves trying to explain it. However, I've heard a graspable explanation of it from an old Chinese battery manufacturer/expert very recently. Which is: The "C Rating" is the number which you multiply to the capacity of the battery to get its discharge rate.
OLithium Ion (Li-Ion) - This was the latest battery technology before lithium polymer. They have a higher power density than NiMh and NiCd batteries. Li-Ion batteries generally come standard with most phones. For most people, this battery technology represents the best combination of size, capacity, and value. These types of batteries don't suffer from the poor memory effect and can be recharged anytime.
Some years lithium mines ontario had more than one Privy mark coin issued for example had a Fireworks an Expo Hanover and a Year of the Dragon. There has been a theme of the Chinese Zodiac series and covered all 12 months.
The i3 concept lends its modified electric dive system to the i8 concept, which takes the game further with its engine that presents 220 hp and 300 Nm torque. The powerful engine provides incredible performance for a sports car, but the fuel consumption is similar to that of a smaller vehicle. It has a very fast acceleration, so quick, in fact, that the car's speed can go to 62 mph from 0 in just 5 seconds. The fuel consumption is also at a remarkable rate at with 3 liters consumed for every 100 kilometers. This means that the i8 has a much better efficiency than the cars today with the same performance.
