My charger manual has the following note:</p></font><font face="ArialMT"><font face="ArialMT">

<font size="2">"Some rechargeable batteries are said to have a memory effect. If they are</font></p>

<font size="2">partly used and recharged before the whole charge is drawn out,</font></p>

<font size="2">they‘remember’ this and next time will only use that part of their capacity. This</font></p>

<font size="2">is a ‘memory effect’. NiCd and NiMH batteries are said to suffer from memory</font></p>

<font size="2">effect. They prefer complete cycles; fully charge then use until empty, do not</font></p>

<font size="2">recharge before storage-allow them to self-discharge during storage. NiMH</font></p>

<font size="2">batteries have less memory effect than NiCd."</font></p></font></font>

<font size="2">Is that old-time technology?</font></p>
