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.

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).

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.

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.

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.

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

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

Suggest to adjust the knob of the charger to make charging current at 6A (the maximum) and charge for 30 mins.

Some laptops take Ni-Cd cells as well as Ni-Mh. However, we do not recommend changing the cell chemistry.

A good charger incorporates several of the features which are also found in Li-Ion chargers. However, these chargers are not compatible with both types of cells unless specifically designed for this job. The chargers may also include V detection delay for more accurate sensing of this parameter.

Yes. We do refill service for Li-Ion batteries. Refill service for the Li-Ion battery pack requires not only special equipment, but also years of technical expertise.
