DigitalDeliveryWorld.Com HOW TO FIX YOUR NiCd BATTERY INTRODUCTION This book will give you the required information on your NiCd batteries to help you better understand the lifecycle of NiCd. It will also show you how to re-energize and revive these batteries through the “RVD” (Re-vitalization through Vaporization of Dendrites) process. We will also discuss the effect of RVD process on the NiCd. We strongly suggest that you read the whole book before subjecting your NiCd batteries to the RVD process. At the end of their usual life-cycle, NiCd batteries often die in such a way that they no longer take a charge and have zero voltage. This usually means they're shorted out by crystal dendrites growth. We will explain what these crystals and how they are formed. By eliminating the accumulated dendrites, the NiCd batteries can be given extended lease on life! We will show you how desirables results can be achieved through the RVD process. The RVD process works on a simple principle of using electric pulses to vaporize crystal dendrites from the cell plates, thus making the battery rechargeable again. One can use a car battery as a power source. Other choices might include a battery charger, a DC power supply, a welder, or almost anything with some DC voltage. Charged-up capacitors are also useful to provide the required surge for the RVD process as quick electrical pulses can be sent through them while still limiting the maximum surge. We live in the wireless age. Cordless drills, cellular and portable phones, Electric toothbrushes, cordless shavers, and many other home appliances rely on rechargeable batteries to keep them wireless. We all have faced the dilemma of what to do with a given appliance, big or small, when the batteries run out of juice. We want to be fiscally responsible and environment friendly, but what good is a device without power? Should we throw it out and just buy ourselves a new gadget? Most of us do just that as cost of replacing the battery, often times, is so ridiculously high that getting a new device is a no-brainer. Well, not anymore! Now you can give a new life to your NiCd batteries that don't hold charge by re-energizing them using our RVD process. 99% of NiCad batteries can be re-incarnated and given a new lease on life including: Black and Decker, Dewalt, Ryobi, Panasonic, Makita, Porter Cable, Bosch, Craftsman etc . When a Firestorm or Versapak NiCad battery would no longer hold a charge or is close to being useless, just apply the RVD process. Your wallet and the environment would thank you! We hope you will find the information useful, and will take the safety precautions during all your RVD processes. Special precautions must be taken to avoid NiCd battery fire up or explosion that can cause serious injuries. Page 5 of 35

DigitalDeliveryWorld.Com HOW TO FIX YOUR NiCd BATTERY OVERVIEW Nickel Cadmium (NiCd) is one of the most established amongst the various commercially available rechargeable battery systems. The energy density of NiCd batteries are lower than the newer battery systems, such as Nickel Metal Hydride and Lithium-Ion. However, the robust NiCd batteries are very durable, reliable, easy-to-use and economical. They remain a popular choice for many electrical and electronic applications that emphasize lower cost while maintaining good performance. Page 6 of 35

DigitalDeliveryWorld.Com HOW TO FIX YOUR NiCd BATTERY NiCd PRINCIPLE As with any other rechargeable battery systems, NiCd batteries operate on the principle that electrochemical reactions at each of the electrodes are reversible; this enables energy to be stored during charging and released during discharging. In the event of deep discharge, depreciation of battery performance may occur. To minimize the possibility of damage, the “antipolar material” (i.e. the active material used in the negative electrode) is added in the positive electrode to prevent the generation of hydrogen gas, which can increase the internal pressure and may destroy the seal or at least cause water loss with resealing valves. NiCd PERFORMANCE There are five major characteristics of NiCd battery that we should look at, which are charging, discharging, storage, cycle life and safety. Page 7 of 35

DigitalDeliveryWorld.Com HOW TO FIX YOUR NiCd BATTERY CHARGING A battery should always remain cool during charging because high temperatures shorten battery life. Some temperature rise with nickel-based batteries cannot be avoided. The time during which the battery temperature remains elevated should be as short as possible. The temperature rise occurs in the second half of the charge cycle. The battery should cool to room temperature when on trickle charge. If the temperature remains above room temperature after a few hours in ready mode, the charger is performing incorrectly. In such as case, remove the battery when ready. Most rechargeable cells are equipped with a safety vent to release excess pressure if over- charged. The safety vent on a nickel-based cell opens between 10-13 Bar (150-200 psi). (The pressure of a car tire is about 2.3 Bar or 35 psi.) With a reseal able vent, no damage occurs after venting. Some electrolyte is lost and the seal may leak afterwards. A white powder accumulating at the vent opening indicates venting activities. Page 8 of 35

DigitalDeliveryWorld.Com HOW TO FIX YOUR NiCd BATTERY CHARGING METHOD The main concern in charging a NiCd battery is the build-up of temperature and internal pressure due to high overcharge rates. The cell design applies the concept of oxygen recombination in lowering the battery's internal oxygen level during standard charging. However, if the cell is subjected to severe charging conditions (such as overcharging at a current rate over 1C), the rate of oxygen evolution from the positive electrode increases rapidly, exceeding the recombination reaction rate. As the oxygen recombination reaction is exothermic, this results in excessive oxygen pressure and increased temperature. The excessive pressure will then be released through the safety vent causing a reduction in the cell electrolyte; the excessive heat will eventually degrade the cell's internal contents. These two factors are considered to be the major limitations to the battery's service life. The overall charge efficiency of nickel-cadmium is about 90% if fast charged at 1C. On a 0.1C overnight charge, the efficiency drops to 70% and the charge time is 14 hours or longer. The C-rate is a unit by which charge and discharge currents are scaled. A charge current of 1000mAh, or 1C, will charge a 1000mAh battery in slightly more than one hour. A 1C discharge lasts one hour. Page 9 of 35
