FAQ

In this section, you will find all the frequently-asked-questions concerning cell and battery technology. If you do not find your answer here, do not hesitate to contact us.

WHAT IS AN ELECTRICAL ACCUMULATOR?

An electrical accumulator is a reservoir that stores energy to later release it.

WHAT IS A BATTERY?

A battery is made up of a set of electrical accumulators linked to each other to create a direct current generator that delivers the desired voltage and capacity.

WHAT ARE THE DIFFERENT BATTERY TECHNOLOGIES?

There are four types of technologies:

  • lead acid 
  • nickel-cadmium (NiCd) 
  • nickel-metal hydrure (NiMh) 
  • lithium (Li-Ion, LiFePO4, Li-Po)

HOW CAN I CHOOSE THE BEST BATTERY?

To correctly choose your battery, a number of parameters are to be taken into consideration:

  • Application: stationary, mobile, power, emergency … 
  • Conditions for use: temperature, cycling, seasonal … 
  • Restrictions: dimensions, weight, safety…
  • Lifespan

VLAD has acquired a solid expertise to help you define the product that exactly matches your needs.

CAN I REPLACE THE ORIGINAL BATTERY WITH A BATTERY FROM A DIFFERENT BRAND?

It is possible to replace an original battery with a compatible product, provided that it complies with the same features and level of quality.

This is why VLAD offers only compatible batteries that are carefully chosen, assembled with reliable elements from a leading brand, with at least the same features as the original batteries.

Be careful however, as for certain medical applications (defibrillation), we provide only the original batteries.

MY BATTERY RUNS FLAT TOO QUICKLY, CAN I REFURBISH IT?

Send us your faulty battery and our technicians will exchange the faulty accumulators with quality cells adapted to the use of your equipment. The battery will be returned to you in 72h with autonomy equal to or greater than that of the original.

WHAT IS A CELL?

An electric cell is an energy generator that operates via a chemical reaction. This chemical reaction is called oxidation reduction and provides a continuous current.

There are three types of cell technologies:

  • Saline: adapted to intermittent use (ring tones, flashlights, etc.) 
  • Alkaline: provides greater energy density.
    They have a long lifespan and constant voltage. 
  • Lithium: has the best weight/power ratio.
    Very long lifespan

If a device uses a number of cells, you should change them all at the same time to prevent new batteries from compensating for the weakness of older batteries and therefore deteriorating more quickly.
