FAQ about Battery

Battery Glossary

  • Battery Charge: This is the process of passing electricity into the battery pack so the pack can be used to provide power when the user is away from mains power 
  • Li-ion: Lithium Ion. This is one the newest battery types available. It can offer the same power as a Ni-MH battery in a smaller and lighter package. This type does not suffer from 'Memory Effect' but it is expensive to manufacture. 
  • Ni-Cd: Nickel Cadmium. This is one of the oldest battery technologies that are still in use. Usually found only in older equipment or applications that require a high power drain. Very prone to 'Memory Effect'. 
  • Ni-MH: Nickel Metal Hydride. This battery type has virtually replaced the Ni-Cd batteries. This type offers higher capacities, around 30% more than a Ni-Cd cell of the same physical size. This type is also reported to suffer less from 'Memory Effect'. 
  • Battery Float Voltage: A unit for measuring electrical pressure. All batteries provide DC (Direct Current) electricity. It is important to ensure that the equipment you are powering is being provided with the correct volt or else damage may occur.
