 About us

   Prius Hybrid Battery
(also called a "battery pack" because inside it is a string of little batteries, and is usually sold with the associated switches, relays, and computer housed within the same box)

WHEN WILL THE BATTERY FAIL?  First, let us note that it is now apparent that the failure of the hybrid battery (the expensive one) occurs at about ten years.  Except for vehicle used entirely on rough dirt roads, this failure seem unrelated to mileage covered:  we have seen battery failures at as low as 80k miles and some as late as 160k.

WHAT WARNING WILL I HAVE?  Essentially none.  You might hear the fan running hard and long, down by the sill on the right rear door; you might notice the gas engine rarely seems to want to turn off at lights.  Probably, even the best of you out there will not be able to discern any significant change in the battery state behavior on the touchscreen.

CAN I DRIVE THE CAR WHEN THE BATTERY IS BAD?  The red 'triangle of death' will be illuminated, so technically, you really should not.  The car may be willing to proceed for a good number of miles, but the triangle-warning is also the indicator of an overheating system or serious brake fault, and should never be ignored.

Battery Replacement Options
    • We used to rebuild hybrid batteries in house by buying used cells which matched the remaining good ones in the battery pack, and replacing the bad ones (usually one or two cells).  As the batteries aged, and the supply of good cells dwindled, the long-term success rate of this approach became so dismal that it was no longer cost-effective.  We no longer offer hybrid battery repair.

    • We now offer a factory rebuilt battery pack.  It carries a two-year free-replacement parts and labour warranty if we determine that the unit has failed; it is not transferable to another owner of the car.  Further, on the same terms, it carries a third year part-only free-replacement warranty. For current pricing see our Prius home page.

    • Also, we offer a genuine new Toyota hybrid battery.  It carries a one-year free-replacement warranty.  This might be the wiser choice if planning to keep the car much outside of the 3-year span of warranty provided with the rebuilt units.  For current pricing, call our office at 520-294-3572.

    • We do not offer used hybrid battery installation.  It costs too much to figure our that it is bad or nearly so, missing pieces, etc.

No Triangles! That's it for now. Please use the links to learn more about us and our little Independent Prius workshop in Tucson.
