Rechargeable Battery – Cost-Effective Sources of Power

One of the most powerful and useful innovation of modern times is indeed the rechargeable battery.

With increasing demand and use of portable devices by consumers, the need for rechargeable battery power has undergone an upsurge over the years.

Rechargeable Battery

A group of two or more secondary cells when restored to full charge by application of electrical energy is called as a rechargeable battery. These prove cost-effective in comparison to the disposable ones as they do not need constant replacement. All you need to do is keep recharging when the charge is over.

These cheap sources of power have made our life much more convenient. However, they may prove more expensive than the regular disposable ones, but they do provide financial advantage by optimum utilization of the cell.

The rate of recharging batteries has increased substantially over the years, from the times when it used to take as much as 12 to 16 hours, to the charging times of today, an hour or less to recharge it complete.

Now manufacturers are working on new models that promise to increase the life of the batteries. The lifespan depends on many factors such as

  • the chemical makeup,
  • total usage,
  • temperature,
  • humidity
  • and other environmental conditions.


Other crucial factors that contribute to increased lifespan are how they are maintained and the number of life cycles or discharge. The life expectancy of each type is different. recargas telcel

A rechargeable battery made of nickel and cadmium (NiCd) and nickel metal hydrides (NiMH) have less storage capacity, approximately half, of alkaline cells.

They tend to discharge faster and perform less efficiently at lower temperatures. However, the life of rechargeable battery depends completely upon its usage and the power of NiCd and NiMH batteries dies out gradually.

Overcharging is yet another factor that affects life and this can result in overheating producing leakage or overflow of charge.

Rechargeable Battery Types

Many portable compact mobile devices and electronic gadgets run on stored power. Devices like laptop, cell phone, digital camera, camcorder and remote control run on different types of rechargeable batteries. These are listed below:
