&lt;p&gt;Good enough for what ?&lt;/p&gt;
&lt;p&gt;The important thing to remember about batteries is that they provide a finite amount of &lt;em&gt;&lt;strong&gt;charge &lt;/strong&gt;&lt;/em&gt;(&lt;em&gt;ie&lt;/em&gt;, energy).&lt;/p&gt;
&lt;p&gt;So your job, as designer, is to ensure that the amount of &lt;em&gt;&lt;strong&gt;charge&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/strong&gt;&lt;/em&gt;your product uses will give you the required run-time from your batteries.&lt;/p&gt;
&lt;p&gt;The display shows you &lt;em&gt;&lt;strong&gt;charge&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/strong&gt;&lt;/em&gt;here:&lt;/p&gt;

&lt;p&gt;that&amp;#39;s not a good choice for long life - alkaline would be better&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
