Efficient Bosch cooling technology in and around the battery prevents heat damage, gives up to 65% longer run-time and up to 100% longer lifetime.
4.0Ah CoolPack cells have finer 'windings' than 3.0Ah allowing more power density ('fuel (Ah)) in the same pack size and less electrical resistance (so more fuel efficient).
That means less frequent battery charges; and 4.0Ah batteries are fully charged in just 45 minutes (charger AL1860CV)!
Heat commonly caused by electrical resistance can damage or even kill cells. Bosch CoolPack technology inside and around the pack balances and dissipates this heat effectively so the batteries stay cooler and live longer!
