Getting a speedlight requires to buy batteries, but question: what kind of batteries to buy? I am by myself a person who uses a lot of batteries. A lot. My kid has plenty of toys which run by battery energy, so I have my ”energy box”.
To be honest, I am a bit shocked that speedlights are not rechargeable itself, but it is what it is, and here I am wondering about the battery choice.
When buying my first speedlight, I also added into my cart Panasonic Eneloop USB battery charger for AA/AAA batteries, and package of 4 Panasonic Eneloop AA batteries. The cost of these two packages been 398,- NOK. These batteries, according to package, can be charged 2100 times. What is not clear, is how long they might hold contrary to regular, single-use batteries. If I buy for example Varta battery package of 24 at Clas Ohlson, the price is 199,- NOK. So I would have these batteries for 6 changes.
Then I looked into the power specifications of these batteries:
| Panasonic Eneloop AA | Varta Longlife Power | |
| Capacity | 2000mAh | 1500mAh |
| Voltage | 1.2 V | 1.5 V |
To understand this chart better, here is a short description from ChatGPT: ,,The rechargeable batteries have a higher total energy storage capacity (2.4 Wh) compared to the regular batteries (2.25 Wh). Therefore, the rechargeable batteries should theoretically work longer in terms of total energy delivered, assuming similar efficiency and discharge characteristics.”.
In conclusion, I will give a try for rechargeable batteries. According to calculation, this product should be not just financially more better, but also environmentally. #thinkgreen
