Hello, I’m new here and it’s pretty confusing! I’m looking for a source to buy good, less expensive back up batteries online. Advice appreciated. Thanks, Razormom
Hello and welcome! As far as batteries, you can buy them easily on amazon, I caution the off brand batteries as I know people have reported issues with them and issues charging. To make them cheap they short cut on circuitry inside. This could cause failure and even melting/fire in worst case scenario. I did buy a ravpower 2 battery bundle with its own charger for 30 off amazon as a backup. I do not recommend mixing cheap batteries/chargers with the official ones.
I needed a new charger for my 20D and bought one from eBay which also included two non-genuine batteries. They work OK but do not last nearly as long as the genuine Canon batteries that were in the camera when I got it. The message is that non-genuine batteries are cheaper for a reason: they are not as good as the genuine article. You get what you pay for.
