The AEG PRO Li THIUM ION technology protects both battery & machine in 3 ways: 1) Thermal Overload protection The thermal overload protection constantly monitors the temperature of the battery & automatically safeguards against overheating, therefore increasing the life of the battery pack. 2) Current Overload protection Too much current draw can permanently damage the cells of the battery thus reducing battery life. The Pro Lithium Ion current overload protection automatically shuts the battery down if the current levels get too high, but automatically resets its self so there is no loss of productivity. 3) Individual cell monitoring Individual cell monitoring ensures every cell in the battery is performing to its maximum capability to ensure optimum productivity. The cell monitoring also runs throughout the charge process to make sure no cells are damaged at this time. This AEG BS12C2L2 has 2 x PRO Li-Ion 1.5 Ah batteries in a kit box.
