I bought my Canon A550 in May last year and only buy the Energizer Rechargeable Battery a month later when I went shopping in Penang! I clearly remembered that I bought the batteries from Toy ‘R’ Us. 
The batteries finally RIP a few days ago after faithfully serving me for more than a year. Time to get a new one.
Why you have to die when I am financially tight??? 
Stumble it!
You should get Eneloop batteries. They can be charged over a 1000 times.
