STK Sterling TEK charging problem for CAN.NB-2LH type batteries

I don't know if this is the right forum for this, but I had been using these batteries for a Canon EOS Rebel XTI. I got this camera a few years ago off of ebay. I am not sure if the charger came with the camera. However, I know that the batteries use to charge effectively. The charger would show red when the batteries weren't charged, then orange, then green when they were charged. Thursday, it seemed to charge all the batteries, and I didn't use the camera. Something that was weird is that most batteries did not seem to charge very long, Note: I used a surge protector to charge them, instead of the wall like before. Today, I went hiking, and all of the batteries that I tried were not charged at all. One had barely any power left in it. One I was not able to get out of some protective cover, so I didn't use it. I am wondering if anybody has any knowledge of this issue. I never had this happen before, and I would hope to be able to use these batteries. I am hoping that this is either a charger issue, or has something to do with the surge protector being used instead of the wall socket.

I have several STK NB-2LHs to got several years ago for when I want to experiment with my S45.  I have several OEM Canon chargers (that have 4 contacts) and a third-party charger (that only has two contacts.)  The OEM chargers date from the early 2000s.  The third party charger is only a few years old.   It is a Wasabi charger I got from Amazon bundled with two Wasabi NB-2LHs.

My experience with third party Canonish betteries over the years is that they often work well, but sometimes they fail.  I've gotten into the habit of buying new ones every few years so I always have a fresh batch if any of the older ones start acting balky.

I try to stick to STK or Wasabi for third party batteries.  Both have been around for years and have a reputation to maintain.

None of this answers your question exactly, other than maybe hinting that you try a new set of batteries/charger.  They don't cost that much.

I haven't done any comparisons with surge protectors.  I usually plug my chargers into an old Radio Shack outlet strip that doesn't have any surge protectors.  Or straight into the wall.
