One of the characteristics of a ni-cad battery is that it has a memory. A fully charged battery should give you around 1,000 shots. But if you constantly shoot 500 shots and then charge the battery for 7 hours, your battery wouldn't give you 1,000 shots anymore; it would only give around 500 shots. In order to insure that the battery will operate at full capacity, it must be fully discharged and fully recharged occasionally.

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. See similar questions...

Ni-Cd rechargeable batteries are a mixture of Nickel and Cadmium. The cadmium represents +/- 15 of 20% of the battery weight. They are ideal for most types of domestic devices such as alarm-clocks, calculators, remote controls, torches... Ni-MH rechargeable batteries are a mixture of Nickel and Metal Hydride. They are 2 to 3 times more powerful than cadmium-based rechargeables and they have no memory effect. See similar questions...

The Olympus Ni-MH batteries will provide approximately 200 shots with typical usage (half of the images shot with flash/half without flash and minimal use of the LCD monitor). See similar questions...

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. See similar questions...

What is a battery? 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. See similar questions...

This is due to Digital Memory Effect (please read faq #20). All refilled laptop batteries are required to be fully charged/discharged a minimum of 3 times (3 cycles). Some batteries require over 10 cycles to fully recognize their new refilled cell capacity. Here is an e-mail from one of our customers: I also purchased the battery refill at BatteryRefill.com about a month ago. However, the battery situation was exactly the same as before.

All refilled batteries has to be fully charged/discharged at least 1 to 3 times(3 cycles)depending on your computer. Some batteries require more than 10 cycles to fully recognize refilled cell capacity. This is because of the Digital Memory effect. To change memorized charging capacity prior to refill, you need to reset power Options. Follow these steps, After changing these settings, charge and discharge battery fully one to three times.

Ni-Cd batteries must be fully discharged every 5 to 10 charges to avoid memory effect. If the battery has not been entirely discharged, the charge will not be complete and will set a new lower energy capacity. This is called the 'memory effect'. See similar questions...

The memory effect does not occur with Nickel-Metal Hydride batteries. They can then be recharged before being fully discharged. See similar questions...

Ni-Mh batteries can be recharged up to 1000 times* and can reduce the volume of waste batteries by 1000 times* and can help you saving money! However it is important to store them in good conditions to keep them longer. * depending on usage See similar questions...
