5 Ways Hybrid Battery Packs are Being Improved

Less Expensive Batteries

One of the biggest turnoffs for potential hybrid car buyers is the high cost of a replacement battery. Battery packs, which typically cost about $3,000, represent a significant percentage of the total vehicle cost. The fear of battery replacement due to failure has led many drivers to hold back on making a hybrid car purchase.

But battery prices -- along with battery failure rates -- have plunged since the beginning of the decade. To phrase in that a different way, batteries are now less expensive and last longer than they did in the past. In 2001, battery replacement in a hybrid car cost about $10,000. Recently, however, Honda has cut its battery replacement price from $3,400 to $1,968. In the near future, Toyota also plans to slash its replacement costs from where it stands now at around $3,000. Also, Toyota's out-of-warranty battery replacement rate has plummeted from about 1 percent for the first generation Prius to 0.003 percent for the second generation.
