I ordered five CR2025 batteries on ebay for my Canon Optura 20 camcorder, whose CR2025 backup battery died. Ebay auction page I got a letter in the mail with 5 CR2016 cells, not the 5 CR2025 cells I expected. Unless I'm mistaken, these cells have rather different specifications. Even the seller's page doesn't indicate that CR2016 are a replacement for the CR2025 cells. Should I complain to the seller and demand a replacement? The manual for the camcorder says to use only certain manufacturer's CR2025 (including Maxell, which is what the listing specifies) and that "use of other batteries may present a risk of fire or explosion." What would you do?
