<p data-mce-fragment="1">This battery is compatible with most cartridges up to 11mm in diameter and features a magnetic cart connector with universal 510 threading, making it a breeze to switch out tanks. But that's not all - the PHD 510 Battery also functions as a preheating device, with two dual-mode preheat settings. Cartridge preheat mode heats from the coil up for the first fifteen seconds, while Shell preheat mode heats the entire unit for the next 15-45 seconds. So whether you're looking for fast cartridge heating or more thorough heating of your shell and contents, the Pulsar PHD 510 Battery has you covered.</p> <h3 data-mce-fragment="1"> <strong data-mce-fragment="1">Features:</strong><br data-mce-fragment="1"> </h3> <ul data-mce-fragment="1"> <li><span data-preserver-spaces="true">0.62 x 3.86 inches</span></li> <li><span data-preserver-spaces="true">450mAh battery</span></li> <li><span data-preserver-spaces="true">4 voltage settings (2.8v - 4.0v)</span></li> <li><span data-preserver-spaces="true">Metal body</span></li> <li><span data-preserver-spaces="true">Side button activated</span></li> <li><span data-preserver-spaces="true">Magnetic cartridge drop-in feature</span></li> <li><span data-preserver-spaces="true">510 threaded connection</span></li> <li><span data-preserver-spaces="true">Dual preheat option (Cartridge and Shell preheat modes)</span></li> </ul> <ul data-mce-fragment="1"></ul>
