Prius Battery Specifications:
There are two batteries found in a Prius. The first is a lead-acid (Pb-A) 12v accessory battery which is commonly found in most vehicles on the road. The second is the main hybrid driving battery, which is specific to hybrid electric vehicles (HEV) and electric vehicles (EV). We at TPB are primarily concerned with the latter.
Starting in 2004 to the current models, the standard Prius battery is a Panasonic Metal Case Prismatic Module. Prior to 2004 and as early as 2000 the battery used was a Panasonic Plastic Case Prismatic Module. The first generation was sold only in Japan. Of the 70,000 sold a small but significant number of vehicles had problems with the battery pack. Furthermore, the battery pack was so large it took up the entire space between the trunk and the cabin. This led to changes in the Generation II models whose stacks were significantly smaller and far more reliable.

2012 Toyota Prius C review
Many Toyota Prius users are thrilled by the efficiency the hybrid has to offer, but want just a little more out of their car. As a result, many owners hack their car in order to achieve a variety of results. These include increasing mileage and running on electric power only (called "EV" mode).
While many hacks can be performed by the average user, you should understand the risks involved in the process before modifying your Prius. Often undertaking such modifications will void your car's warranty (most importantly the battery warranty). It is also possible to damage your car if hacked incorrectly.
