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

A convenient thing if you use a Petzl headlamp regularly. After switching from batteries, there's really less hassle: charge via USB and forget about it. No need to constantly buy new batteries. The operating time depends on the mode, but in real use it holds up well, and most importantly – it charges without problems and stably. One nuance: in the cold, any battery loses capacity, so in winter it's better to keep the headlamp closer to your body or have a spare option. Also, if the lamp sits unused for a long time, it's better not to leave the battery completely discharged. Overall, I'm satisfied with the purchase. For frequent use, it's much more practical than conventional batteries.

I've been using it for some time with a headlamp and it's a really convenient solution. Charging via USB is quick and hassle-free, so you don't have to worry about spare batteries when you're out and about. It holds its charge steadily; I haven't noticed any sudden drops in power during nighttime trips. It works very well for everyday use, especially if you use the light often. Another plus is that there’s no memory effect. The downside might be the price compared to regular 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 fast and its performance is very good.

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

A superb accessory. A great addition for Petzl headlamps, especially for being able to use the lamp's full power. Super fast and easy to use, very easy to charge thanks to the USB-C port, including a charging indicator with coloured LED. Absolutely recommended.

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