Just got my last batch of 3600's yesterday and Over the next week or so I will put them through the testing phases to see whats what.
So far to date the three four cell packs I have been driving with have given me great performance and runtimes. I will see how these new six cell packs compare with a newer 3600 Sanyo matched pack I got from Itegy. I will post the results soon.
Thanks,
Stephen <><
