It's often a quoted concern of hybrid owners and hybrid haters, will the battery hold up in hybrid cars, and how much will it cost to replace?

Hybrid batteries work like the lead-acid batteries (in gasoline only cars) in that they produce energy through a chemical process. What's unlike your typical battery, is the hybrid battery is made up of hundreds of cells filled with a nickel metal hydride (NiMH).

From all reports (admittedly from the carmakers themselves), these batteries have been very reliable. They have also been tested by government agencies with great results.

But they are expensive to replace, typically costing two or three thousand dollars. Prices of hybrid batteries should come down as more and more companies get in on the act and that is happening as sales of hybrids continue to increase.

In the meantime, carmakers have been willing to warranty these batteries for a lifetime, i.e. 8 years or 80,000 miles. Note that in California the requirements are for 10 years or 100,000 miles.

If a hybrid battery does die, it can cost thousands to replace. Like all depleted batteries, hybrid batteries should be treated as hazardous waste and recycled. These batteries can be fully recycled, however. Toyota has set a bounty of $200 on hybrid batteries and followed up by placing a phone number on each battery.
