Yep, the older models had charging cradles that sometimes died within a year and they had to be re-designed and eventually replaced. One thing that also took me a long time to realize with the original battery in my Harmony One is that with these rechargeable Lithium batteries you have to practically run them down to almost nothing before you recharge it again otherwise if you place the remote back in the charger every time you are not using it, it prematurely starts to lose its ability to hold the charge for any length of time. I was making the mistake of doing the above and it got to the point that within a year it wouldn't hold its charge for more than a few hours and I had to replace the battery before its time.
