Battery eliminator
From ArticleWorld
A battery eliminator is an electrical device that acquires power from a source other than a normal battery and converts it into a direct current (DC) quantity that can be utilized for operating another device. A battery eliminator eliminates the need to recharge or replace batteries.
True to its name, the 'eliminator' does away with obsolete designs of batteries, apart from getting rid of the main disadvantages that accompany the use of normal batteries.

Need for the battery eliminator
The main drawbacks of conventional batteries are listed below:
- There is a likelihood of loss of charge even if the battery is not used for a long period of time. This applies to batteries comprised of dry cells.
- There are constant hassles of recharging batteries, if it is possible to recharge them. This applies to rechargeable lead acid batteries. There are added arrangements made to ensure timely recharging.
- Batteries, both lead-acid and dry cell batteries often tend to be very bulky and difficult to transport. If it easy to set up a battery eliminator apparatus, it is often preferred to use the conventional batteries.
- Conventional batteries may not be suitable when different values of DC output terminal voltages are to be used, as in experimental purposes. A battery eliminator offers the convenience of changing terminal voltages simply by the use of a variable switch.
- Battery eliminators do away with the problem of leakage which is seen due to improper handling of conventional batteries. Battery acid leakage can affect structures like pipes and wheels in vehicles.

Drawbacks of battery eliminator
- Battery eliminators fail to work in the absence of a constant source of alternating current power.
- Battery eliminators cannot form a substitute for situations where it is necessary to store electric power.
