Recondition Old Batteries – Give Dead Rechargeable Batteries A New Life

Rechargeable batteries over time decline in performance. Each charge they take will last a shorter and shorter time, until ultimately they are no longer usable. Before you throw them away, did you know you can recondition old batteries? A few easy to learn techniques can restore seemingly dead batteries to their former glory. Saving you money and time searching for replacements.

Electrical power from batteries is one of the greenest forms of energy, and is becoming more and more popular. Not just for powering hand held devices like lap tops and phones, but increasingly to power our cars and for storing power from solar panels or wind turbines in our homes. To be used when the sun doesn’t shine or the wind isn’t blowing. All of these forms of battery usage will only increase in the future.

Unfortunately the batteries themselves pose an environmental problem. As they contain toxic chemicals and materials that often pose a headache to dispose of cleanly. So prolonging their life not only saves you money and indeed can earn you money, but also reduces disposal problems. Using our rechargeable batteries longer makes them a lot greener.

Restoring these types of batteries is not a hard process, once you know what to do. The process can be done in your home with basic tools, and a few safety precautions. It works on the vast majority of batteries and a simple test will tell you if it is worth doing on any particular battery that you come across.

The great thing is that you can save a fortune and even make some good money by restoring batteries. Either for your own use or selling them on for less than a new battery would cost. It is possible you can pick up batteries that you can work on for free, as most people have no idea of how to dispose of them and will be glad that you will take them off their hands.

As you can see learning how to recondition old batteries can be profitable in many ways, and is going to benefit from a growing demand in the future.

Memory effect is a term that is thrown around with talking about a rechargeable battery, but there are a lot of misconceptions around what memory effect is. Memory effect is where batteries aren’t able to hold as much charge as they once could.

When a user experiences less capacity in the battery than they once had, they believe that this is memory effect, which is not the case.

The most common reasons for batteries no longer outputting as they once did are the following:

1) Over-Charging: Charging aa rechargeable batteries, even the best rechargeable batteries, for too long will result in the peak voltage dropping off much more quickly than it once used to. It would appear to an end-user that the battery capacity had in fact decreased, however this is not the case. The is more common in high-drain consumer electronics such as handheld devices and digital cameras. The device is expecting to see the higher voltage, else it produces a low battery warning or similar. Some electronic devices which are not high-drain may not even see any difference if the battery has a voltage drop. Over-charging is much more likely with cheap trickle (slow) chargers.

2) Age and Use: Shock horror, the more you use a rechargeable battery, the less effective it is due to chemical reactions! It doesn’t matter whether you run Duracell rechargeable batteries, or a no-name brand, eventually they are all going to be less effective than they once were. The thing to look out for is the number of expected recharges you can get out of a battery. Many of the Duracell rechargeable batteries will give you around 1000 charges before their life ends. Looking at the grand scheme of things, this is potentially one full charge every day for a few years! Every rechargeable battery also has an effective life, before you will begin to see some degradation of capacity, once again a good rechargeable battery will give you at least a year or two. If you are a regular user of batteries you will make your cash back tenfold before requiring to purchase new batteries, in comparison to purchasing single use batteries.

So should you fully discharge a battery before recharging?

Draining a battery to 0 volts (completely dead) can potentially cause damage, leading to a reduction in life of rechargeable batteries. If you obtain Duracell rechargeable batteries which potentially give you 1000 full charges and have a battery with 90% charge remaining, would you really want to flatten it fully with a charger (many do this for you) before recharging?

Use the batteries normally and when performance is no longer acceptable then just recharge them again. If this is truly bugging you then some of the top rechargeable battery chargers will let you discharge a battery to a specified voltage, before the recharging cycle begins. This is more friendly for the battery life than draining it completely to 0 volts and is similar to what would happen if you used rechargeable batteries in a digital camera. A digital camera will not drain them to 0 volts, it requires a certain voltage in order for the camera to switch on.

So what should you do?

People are unnecessarily caught up stressing about memory effect, and things that look like memory effect. Duracell rechargeable batteries or any of the best rechargeable batteries will most likely do the job, so just run out and get some and stop worrying.

Let’s say you spend $20.00 on 4 AA Duracell rechargeable batteries and give them only 100 of the 1000 suggested charges over a couple of years, which they will easily achieve, each battery will end up costing 5c a charge ($20.00 / 4 / 100).

Good luck finding single use disposable batteries at these prices!
