EnerSys batteries are powering tunneling equipment beneath London. Its Hawker range of batteries is used in maintenance locomotives that install and inspect power cables. The 200V Hawker Perfect Plus batteries with 1240A/h or 750A/h capacities are ideal for the gruelling conditions demanded in the tunnelling work.
The valve-regulated lead-acid battery range supply high power and long running times, the construction of the plates using advanced components allows for far more efficient discharge over other batteries.
The demands of a subterranean locomotive on its power source are high. The battery must be the right size and weight for the locomotive and must work for the length, and number of, trips required on a shift.
