Duracell

Duracell is well known for their AA and AAA batteries but Duracell have been making top quality car and marine batteries for a long time. Made in the US, these batteries are now available in Australia. The East Penn manufacturing plant where these batteries come from is commonly regarded as the top battery manufacturing site and this clearly holds true if you compare Duracell to other quality brands.
As it is is common with other US batteries, the specifications are significantly under the real world values and you can count on the fact the battery will perform between 10% - 30% above the specification! Duracell batteries come in standard "wet" (or flooded) and super high performance AGM versions.
