Ni-MH Battery Reconditioning

Ni-MH batteries are basically an extension from the verified sealed Ni-Cad battery technological innovation together with the replacement of the hydrogen-absorbing negative electrode for the cadmium-based electrode.

The replacement boosts the battery’s electrical potential, measured in ampere-hours, for any provided weight as well as volume and also gets rid of the cadmium which often increases toxicity worries, the rest of the nickel-metal hydride electric battery is rather identical to the nickel-cadmium.

Ni-MH batteries are available in several types from AA, AAA, D, C to 9volt.

And you may also get battery packages that contain Ni-MH electric batteries. Ni-MH is a type of rechargeable battery that has followed and also substituted Ni-Cad rechargeable batteries.

The Ni-Cad has been surpassed in a few ways:

  • They store more charge and last longer than the Ni-Cad batteries which are of the same size
  • Ni-MH does not suffer memory effects. Even though they suffer from voltage depression which is similar but not as serious as that of the Ni-Cad
  • The critical dissimilarities that exist in between the Ni-MH and the Ni-Cad is chemical. Cadmium does not exist in Ni-MH batteries.

The chemical is very hard to get rid of, environmentally and this makes them be lucrative to produce. Since they are very familiar, it is very essential to understand how reconditioning of Ni-MH batteries is done.

How to Recondition Ni-MH Batteries

Since we are now conversant with what Ni-MH is, we can dwell on how a reconditioning is performed.

I highly recommend learning more about the EZ Battery Reconditioning wave that’s hit recently.

You do not necessarily have to open up the batteries in order to recondition. It involves carrying out deep charge cycles to the battery so that it can regain the lost performance.

There exist other ways that will assist your Ni-MH store their power long and also retain it with time. The tips include:

  1. Make sure that the Ni-MH batteries are fully charged
  2. Fully discharge the Ni-MH batteries – You can even let the gadget stay on so that they can completely drain the batteries.
  3. Re-do Step One and Two – The two steps are called charge cycles. It is akin to an exercise, but for batteries, in order for them to regain fitness.

If you possess a rechargeable battery which is unable to store charge after cycling, this can signify that you will have to rejuvenate it.

Tips that will help maintain the NiMH battery charge

Charge cycles are very beneficial to rechargeable NiMH batteries. If you possess a device that is powered by a NiMH battery and takes long to discharge, you need to ensure that you remove the batteries after duration of 3-6 months and carry out a charge cycle on them.

When you fully charge the NiMH batteries that you dont intend to utilize instantly, you can wrap them and put the freezer. This is because the NiMH batteries discharge a lot quicker when they are warm or rather in a warm environment.

When they are in a room temperature, they will lose approximately 30-50% of their charge in a span of one month. If you keep them inside a freezer which you need to ensure that moisture does not penetrate into, they will last a little longer. Moisture penetration causes corrosion.

Application of Ni-Mh Batteries

Ni-MH has a widespread application in today’s context. It is mainly used in high electronic products which are usually portable and their battery performance requirements, usually the run time, is the greatest concern before an individual can make a purchase decision. They are put to use in:

  • Digital cameras
  • GPS units
  • Hand held games
  • Portable music players
  • Public Digital Assistants
  • Toys and Video devices
