The Makita 12-Volt 2.6 Ah Ni-MH Battery Pack produces up to 70 percent longer run time than standard Ni-Cad batteries. These pod-style Ni-MH batteries are environmentally friendly with literally no "memory effect." The multi-contact terminals ensure a tight connection to the power tool even under extreme vibration. Shock-absorbing construction protects battery cells against dust and vibration.
