Thanks for the link to the thread..
It was a very informative thread...

But I think, most of the problems came out because the charger "fried" the batteries.... in a sense that most of them had their covers peeled off.

But IMO, this problem lies mostly with the batteries itself.
The Rayovac pumps as much as 1++ amp. into the batteries, and the batts will naturally get hot.

If the batts are sub-standard, I think the heat will make the batt covers peel off...

So should the problem lie on the charger or the batt?
My hunch points at the batts...

Anyone would like to comment about this?
 

depnd on the batt, as most of the rechargeable batt does have much durable cover in order to hold the heat that are flowing thru, consider GPSmart 1 hrs charger which charge any mah in/below 1 hrs, just imagine if u keep using the batt on cam and it get so hot, the cover does obstruct the handling toand from the batt slot on the cam if...the cover peel off

Hmm..
But GP Smart 1 hour charger is also a rapid charger right?
It will also have the same problem... Since they are all 1 hour rapid chargers.

It's the current passing through that heats up the batts..
So any charger which pumps in current furiously will have this problem...

So far, no problems with my Sanyos on my Rayovac.. I hope.
 

No problems with my sony, gp and rayovac batteries.
 

IMO, this is the drawback of utilising a charging current which is too high, especially when you have not so ideal operating environments and perhaps lower quality rechargeable batteries. I wonder if there is any relation to the price reduction of the Rayovac 1hr chargers?!!
