Positive: Lower costs
The cost-effectiveness of third-party batteries is the main justification for doing so. The producer of the camera creates OEM batteries. They therefore cost more than average.
Even a few more name-brand batteries may set you back several hundred dollars. The EN-EL18d, a brand-new Nikon battery that will be available in 2022, is quite expensive.
You are, in a sense, paying more for your added piece of mind. The manufacturers of cameras are aware that some photographers prefer to purchase name-brand products. The product may not necessarily be better because the price is more.
The price of an external camera battery is lower. The cost of good replacement batteries is typically between a quarter and half that of OEM batteries.
It’s possible that you won’t even be able to tell the difference between a name-brand and an aftermarket battery. But occasionally, you could receive what you pay for.
Cons: Lessened Strength and Durability
Users occasionally complain that aftermarket batteries don’t last as long as their brand-name relatives. When capturing images, they can run out more quickly. They could also have shorter lives.
This is sometimes anticipated. You may not always get the same capacity from third-party batteries as you would from their equivalents.
Although a battery might work with your camera, it might not have the same specifications. Consider the milliampere-hour (mAh) values for the Wasabi equivalent and the EN-EL15c from Nikon.
The 2280 mAh brand-name battery has. Wasabi features a 2000mAh battery. The greater number in the battery provides you more operational time, other factors being equal.
You might not be able to use your camera’s maximum frame rate with weaker batteries. This isn’t inherently a problem; just remember to be reasonable in your expectations.
However, aftermarket batteries aren’t necessarily inferior to their original equivalents in terms of strength. More storage capacity is available in many good aftermarket batteries.
Pro: Serious issues Rarely do photographers utilize aftermarket batteries when OEM batteries are unavailable, or stocks are low. Worrying issues are noted in certain reviews of batteries from third parties… the most concerning being a camera explosion caused by a battery!
The following are some other worst-case scenarios:
Batteries can heat up or bulge over time.
The battery is not recognized by the camera.
Cheap batteries sabotage camera equipment.
However, complaints of these problems seem to be infrequent when using aftermarket batteries made by reputable businesses. Most online reviewers are satisfied with their selection. Additionally, their worries are not overly extreme.
