What is a battery?

A battery can be any device that stores energy for later use. The word battery is limited to an electrochemical device that converts chemical energy into electricity, by use of a galvanic cell. A galvanic cell is a fairly simple device consisting of two electrodes (an anode and a cathode) and an electrolyte solution. Batteries consist of one or more galvanic cells. A battery is an electrical storage device. Batteries do not make electricity, they store it. As chemicals in the battery change, electrical energy is stored or released. In rechargeable batteries this process can be repeated many times. A battery is an electrical storage device. Batteries do not make electricity, they store it.

What is an Amp Hour Rating?

An Amp Hour Rating is dependant on the time which is specified. Eg: A new battery with a 20 amp hour rating will deliver a minimum of 1.75 volts per cell over a 20 hour period at 25 degrees Celsius. This described as “Amp Hours”. To select the correct deep cycle battery with an amp hour rating for your specific use, you should consider the hours of use before the battery must be recharged and the amount of power or watts for each piece of electrical equipment you are intending to use. This can be done by multiplying by the amount of watts by the hours required and then dividing these by the voltage be it either 6, 8 or 12 volt system to determine the required AH (Amp Hour) required.

How can batteries be connected?

Series (pos to neg) When interconnecting batteries (cells), they must be identical in voltage and amp rating! Batteries may be connected in series. The positive terminal of the first battery is connected to the negative terminal of the second battery; the positive terminal of the second is connected to the negative of the third, and so on. The voltage of the assembled battery is the sum of the individual batteries. The batteries are connected: + to – to + to – to + to -, etc. The capacity of the battery is unchanged. Parallel (pos to pos) Batteries may also be connected in parallel. The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third; the negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third and so on. The batteries are connected: + to + to + and – to – to -. In this configuration, the capacity is the sum of the individual batteries and voltage is unchanged. For example, (5) 6V 10AH batteries connected in series produces a battery array that is 30 Volts and 10AH. Connecting the batteries in parallel produces a battery array that is 6 Volts and 50AH. Ordinary auto batteries are designed in the same fashion. Six 2-volt cells are arranged in series to produce a 12v battery. Many Ni-Cd batteries are arranged in the same way.

What is a valid warranty?

The warranty for batteries, like for most manufactured goods, is a warranty against faulty materials and workmanship. The warranty period in months for each product type is indicated in each of the battery as well as in the application manual. As soon as it is determined that the battery is defective and is within its specified warranty, due to faulty manufacturing, it will be replaced with an equivalent battery free of charge. The guarantee is void if the battery has been subjected to overcharging, abuse, faulty vehicle charging system, neglect, failure to maintain acid (water) levels, tampering of markings or broken or removed vent plugs. Failure to use distilled water when topping up a battery will also void warranty. Installing a battery that has a lower capacity than is originally specified by the manufacturer of the equipment will likewise void warranty. Warranty periods indicated are for private use only. A 12-month warranty applies for commercial use. A 6-month warranty applies for taxi use. Proof of purchase is needed to claim warranty.

How do I identify my battery?

The first information to provide would be the make and model of the equipment that you require the battery for. There is also usually a label on the battery, and some of this information on the label will help our sales team to identify your battery quickly. This information includes the voltage of the battery pack (note: this is not the same as the voltage on the power supply), the capacity of the battery pack and the chemical construction of the battery pack e.g.Li-ion, Ni-MH or Ni-Cd. This information can be used to ensure the information you have provided matches the information we have about your battery. Many battery packs also have part numbers on the label; this can sometimes be used to help identify the battery. We would suggest that it is best to have all this information written down or close to hand before you call our sales team. This will help us deal with your call in an efficient manner.

How long will the new main battery power the laptop?

Battery run-time on a laptop is difficult to determine. Actual battery running time depends upon the power demands made by the equipment. The use of the screen, the hard drive and other accessories results in an additional drain upon the battery, effectively reducing its running time. The total run-time of the batter y is also dependent upon the design of the equipment. Generally, a new Hi-Capacity battery will run 30% to 50% longer than the old battery did when it was new.

How long do batteries last?

The life of a Notebook battery is about 1.5 to 3 years operating under normal conditions. As the rechargeable battery begins to die, the user will notice a decline in the running time of the battery.

What is the %22Memory Effect%22?

Ni-Cd batteries, and to a lesser extent Ni-MH batteries, suffer from what’s called the “memory effect”. What this means is that if a battery is repeatedly only partially discharged before recharging, the battery “forgets” that it has the capacity to further discharge all the way down. To illustrate: If you, on a regular basis, fully charge your battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of its extra 50% capacity which has remained unused. The battery will remain functional, but only at 50% of its original capacity. The way to avoid the dreaded “memory effect” is to fully cycle (fully charge and then fully discharge) the battery at least once every two to three weeks. Batteries can be discharged by unplugging the device’s AC adapter and letting the device run on the battery until it ceases to function. This will insure your battery remains healthy.

Does it really help to store batteries in the refrigerator?

Yes, but only if they can be kept dry as well, the higher the temperature, the more the free flow of ions or self-discharge from the battery. Storing primary batteries (D’s, C’s, AA’s, AAA’s, 9 volt, etc.) in a cooler environment slows down this rate of discharge that all batteries experience even when not in use, hence a longer shelf life. However, if this is done, it is important that the batteries be kept as dry as possible by keeping them in an airtight container in the driest part of the refrigerator, the door for example. Long term exposure to moisture inside the refrigerator can cause internal corrosion to the battery. Always allow batteries to warm up to room temperature before using them in your device.

What is a CCA and RC Rating?

CCA (Cold Cranking Amperes) is an international standard for measuring the performance (current in amperes) of the battery. CCA measures the cranking capacity of a battery at a fixed temperature (at -18 degrees Celsius) and maintain a terminal voltage of 1.2 volts per cell or more (under load). This standardized system of measurement has been adopted to be the only true comparison of starting power between batteries. RC (Reserve Capacity) is another international standard for measuring the performance of the battery. RC measures how many minutes a battery can supply the electrical load of a vehicle once the charging system has failed. The more accessories are added in the vehicle the higher the RC requirements are needed. Both CCA and RC are the benchmark measurements that Original Equipment Manufacturers and Automotive Electrician/Mechanics use to determine the appropriate replacement battery for the vehicle. In short the higher the CCA of a battery, the more power for the engines cranking ability.
$

What is a battery cycle?

Cycle life is measured by the amount of times a battery may be charged and discharged. Every time a battery is charged and discharged, it uses one cycle. Cycle life is very important in battery applications such as laptop batteries and emergency light batteries. A Ni-Cd battery has a cycle life of about 500-1000 or more cycles.

The rating for batteries

Volts: The voltage of the new battery should always match the voltage of the original. mAh: It stands for milliamp hours(1 mAh=0.001Ah)

Is it true that vehicles will have a hard time charging Calcium Batteries?

New vehicles because of the additional accessories and equipment are designed to require a fully sealed calcium-calcium battery, as evidenced by the new vehicles coming from Europe and Asia. Holden is also releasing its new models with fully sealed calcium-calcium batteries. Moreover, the charging system in these vehicles are designed to charge calcium-calcium batteries and at times will boil a below specification conventional antimonial battery.

What is the difference between Ni-Cd, Ni-MH and Li-ion?

Ni-Cd (Nickel Cadmium). This is one of the older cell types and is generally only found in older laptops. The main pro for this cell type is its ability to handle higher loads, and therefore is more commonly found in portable power tools or devices that need a lot of power to work efficiently. The main downside of this cell type is that it is notorious for suffering with memory effect so good care must be taken with this battery to ensure most effective use of battery.Ni-MH (Nickel Metal Hydride). This cell type is the most common cell type currently available for laptop computers, (although Li-ion is rapidly becoming the most popular) this battery type is relatively cheap to manufacture and therefore tends to be cheaper than Li-ion. Some of these cell type are prone to ‘memory effect’ so it is important to take good care of your Ni-MH battery to ensure that you obtain the best runtimes. Ni-MH (Nickel Metal Hydride). This cell type is the most common cell type currently available for laptop computers, (although Li-ion is rapidly becoming the most popular) this battery type is relatively cheap to manufacture and therefore tends to be cheaper than Li-ion. Some of these cell type are prone to ‘memory effect’ so it is important to take good care of your Ni-MH battery to ensure that you obtain the best runtimes. Li-ion (Lithium Ion). This is one of the newest cell types available. It is also the lightest battery type currently available on a commercial basis and can provide more power than the other main cell types. There are no known problems of memory effect with this battery type and it is the easiest battery type to care for. The downside of this battery is that it has the highest engineering costs and therefore the price is usually considerably higher than other cell types.

How to maximize battery performance

It is recommended to condition (fully charge and discharge) the new battery a few times to allow it to reach its maximum rated capacity.Condition the Ni-MH and Ni-Cd battery at least once a month. It will reduce the memory effect. Condition the Ni-MH and Ni-Cd battery at least once a month. It will reduce the memory effect.Use the battery at least once a month even it was kept in a dry and cool storage. Use the battery at least once a month even it was kept in a dry and cool storage.Clean the metal connector (the contact to the notebook, usually in Clean the metal connector (the contact to the notebook, usually in colour of gold or silver) by alcohol or Electronics Cleaner Degreaser. It will maintain the good conductivity, which improves the power conduction from battery to Notebook. Fully optimize the Power Management features this provides in system BIOS and Operating System will also improve the battery performance. Consult the user’s manual to fully understand the usage of these features.

How do I charge my batteries?

Our Ni-MH chargers are fully automatic. Plug your charger into an A/C power source and place your batteries into the charger in matched pairs of two or four batteries to begin charging. Red lights indicate charging in progress. The lights will turn green when charging is complete and the charger will automatically switch to a trickle charge. The trickle charge will keep your batteries fully charged and ready for use. Refer to our Charger Manuals page for more detailed operating instructions for your model charger.

Can I use my older Ni-Cd battery charger to charge my Ni-MH batteries?

No, you can use a newer Ni-MH charger to charge your old Ni-Cd batteries but you should not try to charge Ni-MH batteries with a Ni-Cd charger. Here’s why: Ni-MH and Ni-Cd batteries are chemically very similar and when both are fully charged the battery voltage will start to drop. The Ni-MH voltage drop is much more subtle and more difficult to detect. Ni-MH chargers usually have over temperature sensor and shutoff to prevent overcharge as well as a more sensitive voltage drop detector where Ni-Cd chargers usually only use the voltage drop to determine when to stop charging. If you charge Ni-MH batteries in a Ni-Cd charger it will probably miss the voltage drop and keep right on charging causing the batteries to overheat. Overcharge and overheating Ni-MH batteries can damage them internally and reduce battery life.
