Every time we use a cordless power tools, be it hedge Trimmer, cordless drill, leaf blower or other type of cordless power tools, we certainly need Cordless tool batteries.
When we choose to buy a cordless power tools, battery voltage is not the only one of the most important factor for our consideration.
Bosch Cordless Tools
Cordless tool batteries available up to 36 volts, but other factors should we take into account also the amp/hour, and battery type too. For 14.4-volt battery and 19.2-volt battery rating will surpass the size of 36-volt battery, if the battery type and amp/hour superior and better than 36-volt sizes.
Rating Basics for Battery
For rate Cordless tool batteries we can use the voltage and amperage hours. Voltage is a measure of the power of an electric current or electric power, while Amperage hours is a measure of how long the battery will last or used.
Based on the information above, the higher voltage followed along with the higher amp/hour will be made more powerful battery. Cordless tool batteries are usually available in sizes 1.4, 2.4 and 3.o amp/hour. We can find the rating amp/hour from a battery at the bottom of the battery or on both sides of the battery.
Types of Battery
Modern cordless power tools have three types of batteries.
Ni-Cad = Nickel-Cadmium (can be 400 times recharged before replacement),
Ni-MH = Nickel Metal Hydride (more than 400 times recharged before replacement),
Li-Ion = Lithium-Ion (more than 1,200 times recharged before replacement claim up by manufacturer).
Charging Time
Many older battery requires recharging for six hours and we can only use for one hour of work time. We need to consider this when we bought Cordless tool batteries, if we have a lot of work would not be time thrown away just to wait for recharging the battery. And to overcome this problem there must be a way out is by using type Li-Ion battery or Lithium-Ion battery which takes only 15 minutes to recharge.
Maintenance and Stability
For the Maintenance and Stability we usually follow the recommendation of the factory, this will cause a high cost in terms of replacement batteries. As well as other parts of the equipment, cordless tool batteries have an expected service life. Often the two battery replacement is more expensive than buying cordless power tools with charge plus two batteries. More economical when buying cordless power tools are new, rather than replace the cordless tool batteries worn out.
