Backed by the power of 56V ARC Lithium technology, the EGO 2.5Ah battery offers long-lasting performance for use in any EGO tool. The industry-leading technology provides optimum performance to achieve the best balance between required power and usable energy. The 2.5Ah ARC lithium battery may be small, but it packs a punch. It has enough power to mow up to 400 square metres of lawn, trim hedges for up to 75 minutes, chainsaw up to 130 times or cut lines for up to 70 minutes (depending on the tool, charge level and conditions of use). When the battery is empty, you can connect it to the standard charger to fully charge it in 50 minutes or to the quick charger to fully charge it in 30 minutes.
