The Petromax 4-piece set of 18650 lithium-ion batteries has been specifically designed for the LM500 LED lantern and offers an impressive capacity of 3450 mAh per battery. This allows for a lighting duration of up to 160 hours on the lowest setting or 5 hours on the highest – ideal for long nights outdoors or relaxed evenings at home. The batteries are temperature resistant up to 45 °C, leak-proof, and pre-charged, so you can get started right away. Charging is incredibly simple: in just 1 hour and 45 minutes, the batteries can be recharged directly in the LM500 via USB-C cable and power adapter. Thanks to their low self-discharge rate, they remain reliably usable even after long storage periods. And if you want to use the batteries for other devices with the 18650 battery type, that’s no problem. Another advantage: the memory effect is a thing of the past with these batteries. You can charge them at any time – regardless of the current charge state – without losing capacity. Whether camping, traveling, or in the garden: with the Petromax 18650 batteries, you have a durable, powerful power source for your LM500 – and always reliable light at hand.
