The revolutionary Odyssey battery achieves both. The Odyssey battery is made from 99.9% pure virgin lead (not lead alloy). Pure lead plates can be made thinner allowing more in the battery- the greater the surface area maens more power! Odyssey batteries are capable of providing cranking pulses in escess of 2250 amps for 5 seconds- this is over double that of conventional batteies. Also they can handle 400 charge-discharge cycles to 80% depth of charge.
