High quality and cheap power tool batteries, such as Makita power tool batteries, Bosch power tools batteries, Dewalt power tool battery, Ryobi power tool batteries, and more. Please select your power tool brand from the list below.
What is the CCA rating?
The cold cranking ampere (CCA) rating refers to the number of amperes a battery can support for 30 seconds at a temperature of 0°F until the battery voltage drops to 1.20 volts per cell, or 7.20 volts for a 12V battery. Thus, a 12V battery that carries a rating of 600 CCA tells us that the battery will provide 600 amperes for 30 seconds at 0°F before the voltage falls to 7.20V.
Do I have to condition my Laptop or Notebook battery?
Yes, it is very important to condition or fully discharger and then fully charger the battery every two to three weeks. Failure to do so may significantly shorten the battery's life (this does not apply to Li-ion batteries, which do not require conditioning). To discharger, simply run the device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in the user's manual
How do I Jump Start my Battery using booster cables?
WARNING-BATTERIES PRODUCE EXPLOSIVE GASES. These instructions are designed to minimize the explosion hazard. Keep sparks, flames and cigarettes away from batteries at all times. Both batteries should be of the same voltage (6, 12, etc.).
What is the pulse cranking amp rating (PCA)?
Unlike CCA and MCA the pulse cranking ampere (PCA) rating does not have an "official" definition; however, we believe that for true engine start purposes, a 30 second discharger is unrealistic. With that in mind, the PCA is a very short duration (typically about 3 seconds) high rate discharger. Because the discharger is for such a short time, it is more like a pulse.
