What is the memory effort?
The memory effect is where if a battery is repeatedly used in the same way, it looses the ability to be used in any other way. For example, if a battery is repeatedly fully charged and then only discharged down to 50% capacity, and then recharged, it will then only be capable of holding half its charge, even though it is fully charged. For this reason, occasionally fully discharging batteries is useful. However, the memory effect only occurs where the use is very repetitive, as it would be in a video camera, for example. In model railway applications, the load on the batteries is very variable, so the memory effect is unlikely. Also, the batteries sold by Antenna Models are manufactured in such a way as to minimise the memory effect.
