I purchased a used canon 350D SLR camera body from amazon . It came with all the necessary wires , software discs, manual and four batteries with charger. I charged one battery for 24 hrs to see the camera operation . A second was on the charger the same amount of time.
As The camera was in use a light kept flashing . I bought these four batteries cheaper than one original battery . I charged one upon opening the package , installed it 24 hrs later . A screen came on to set the time and date . As this was the first time I saw this , the batteries that came with the camera were no doubt old .
These bought from Great Offer Stock were 1/3 the price of name brand and still seem to operate well after one month. A good replacement in my opinion . Will purchase more for backup soon.
