NiCad batteries are much more susceptible to this problem. ‘Memory effect’ occurs when a rechargeable battery is charged consistently at levels above recommended discharge. If 50% of a rechargeable battery’s capacity is used and then the battery is charged – and the battery is constantly used and charged at this level – the other 50% will unfortunately never be used. And so, the battery will only be using half of its power rating. For example, a 1000mAh battery will only be operating at 500mAh. (Because of the advanced NiMH technology, all top NiMH rechargeable batteries do not suffer from 'Memory Effect' )
