I have a Riva 510 (not sure what type of battery is in it - lithium ion, NiMH or whatever else there is out there), and always assumed you should charge a battery fully, then let it drain fully, to avoid memory effect. I've read some posts which suggest you should never let the battery drain, but rather top up charge it. What types of battery are in the 510, and how should you charge and discharge them?
Thanks
