I recondition high-voltage hybrid/traction batteries for all major hybrid and electric vehicle brands: Toyota, Honda, GM, Ford, Nissan, etc. In fact, I can recondition any battery, of any chemistry (NiMH, various Lithium-Ion types, lead-acid, etc) because I can program any (within reason) charge/equalize parameters into my equipment.

Pulsed-mode charging is used, which emulates energy transfers during vehicle operation (pulsed energy transfers from regenerative braking, and to/from motor/generator).

The charge cycles perform equalization/balancing between the battery modules.

Battery protection features that prevent over-voltage and over-current conditions are programmed into the charge cycles.

If you have your own charging algorithm (for example a current-limited slow charge, a special pulsed charge, etc.) I can likely program it into my equipment and charge your battery pack with it.

Note that by reconditioning your own pack you retain your own battery modules, as opposed to buying a pack that contains someone else’s modules with unknown history (and is also likely used or reconditioned, and not new).

Note that conventional multi-stage charging methods, and single- or multi-stage battery chargers, are not appropriate for these hybrid vehicle batteries. Do not use a conventional battery charger or you will destroy your battery, your charger, and maybe yourself. The charging and equalizing of these hybrid batteries requires specialized equipment where the charge parameters are tightly controlled, it requires the knowledge to develop appropriate charge parameters for each battery type/brand, and it requires the knowledge to read the battery condition and to adjust the charge parameters accordingly during the reconditioning operation.

The picture below shows a Gen II  Toyota Prius traction battery pack (28-modules) being reconditioned.

Another picture below shows the reconditioning of a Honda Civic traction battery pack (11 double-stick blocks).


Another picture below shows a large (40 modules, 300+ Volts DC) Chevy Tahoe battery pack being worked on.


And another picture below shows a Honda Accord pack (10 double-stick blocks) being reconditioned.

The prices for these services are as follows:

$500.00 for reconditioning of battery packs with fewer than 40 modules (Toyota Prius, Honda Civic, etc).

$600.00 for reconditioning of battery packs with 40 or more modules (Chevy Tahoe, Lexus RX, etc).

$150.00 minimum charge for the analysis and diagnostics of your battery pack (included in the two charges above).

Extra charge if any bad modules need to be replaced in your battery pack (parts and labor to install), but this can only be determined after the analysis and diagnostics of the pack.

All this assumes that you bring your battery pack to me. Call for some other options for pulling the battery pack out of your vehicle.

Note that this reconditioning process is not a very fast operation, due to the battery chemistry involved, and due to multiple verification steps which are needed to make sure the job is done right. For batteries brought to me in a reasonably good condition, I have had good luck with a 3-day reconditioning process.
