Why? Because with an 18650 battery, you can achieve above-average energy density for easy and long-lasting operation of portable devices with high power requirements. In the DND Telecom webshop you will find Samsung and LG brand 18650 batteries with a capacity of 3500 mAh and a voltage of 3.7 V.


These rechargeable lithium-ion batteries have no memory effect, so they can be used at full capacity for a long time. Why choose a lithium battery? Because this type of mini battery can store around 8-13 watt/hour of energy, while ordinary NiMH batteries can only store 1-3 watt/hour. But that's not the only reason to buy a rechargeable battery.


But also because they offer a cost-effective solution and because using them also helps the environment. Many of you have asked us where we got that strange name. This battery got its name for a reason, because its dimensions are hidden right in its name. Namely, this mini battery has a diameter of 18 mm and a length of 65 mm.
