Instead of three AAA batteries, you can use this battery, which is a very convenient and practical solution. The Petzl battery is high quality and works without any problems. I definitely recommend both this product and the store Militaria.pl.

A convenient thing if you use a Petzl headlamp regularly. After switching from batteries, it's really less hassle: charge it via USB and forget about it, you don't need to keep buying new batteries. The runtime depends on the mode, but in real use it lasts just fine, and most importantly, it charges without any problem and stably. One thing to note: any battery loses power in the cold, so in winter it's better to keep the headlamp closer to your body or have a spare option. Also, if the headlamp lies unused for a long time, it's better not to leave the battery fully discharged. Overall, I am satisfied with the purchase, for frequent use it is much more practical than regular batteries.

I've been using it for some time with my headlamp and it's really a convenient solution. USB charging is fast and hassle-free—no need to worry about spare batteries outdoors. It holds a stable charge, and during night trips I haven't noticed any sudden drops in power. It works very well for everyday use, especially when frequently using the light. Another plus is the lack of memory effect. The downside might be the price compared to ordinary batteries, but the comfort and long-term savings make up for it.

In my opinion, this is an essential accessory for flashlights. You can use it as a backup in your backpack or as the main power source, keeping batteries as a reserve. Charging is quick, and its performance is very good.

Instead of using regular disposable batteries, it's better to buy this rechargeable battery – it lasts long and lets you easily check the charge level.

A great accessory. A fantastic addition for Petzl headlamps, especially to get the full performance out of the lamp. Super quick and easy to use, very easy to charge thanks to the USB-C port, including a charging indicator with colored LED. Absolutely recommended.

The product matches the description and fits the headlamp perfectly, there were no issues with delivery. The charge level indicator works properly and the USB-C port is available.
