+ | [* icon_caution] ***If you buy a used camera (Mirrorless, DSLR, P&S), any batteries included with the camera are likely well-used and may be EOL.*** As a rule, batteries are "consumables" with limited warranty coverage. This is especially true with a used camera. |
+ | [* icon_caution] ***There is no catch-all method for ANY brand; in some cases, monitoring is just going to be poor due to the class or age of the camera (not as bad on more recent cameras).*** On cameras with poor monitoring, you will need to make a judgment call on unreliable data. See this 80D for what proper health monitoring looks like. |
+ | [* red] Refer to your camera's menus and see how to check this, if your camera supports it. ***For example, the battery I got with my Canon 80D is from 6/2017 and is essentially "end of life", as this stuck with a recalibration. I will still use it until it's dead but I do not trust it in the field without a healthy pair of spares.*** |
+ | [* orange] ***The seller this 80D came from "included" this battery, but it likely came from a pile of batteries and was binned as "end of life, include with the 80D". I cannot verify this as an absolute fact, but this practice is VERY common with used cameras.*** |
+ | [* yellow] ***Batteries without monitoring:*** If your battery has no/poor monitoring, look for a date stamp. If it is over 3 years old WITH limited runtime, consider it consumed. |
