Hybrid battery repair, reconditioning and refurbishment

Reconditioning repairs the pack you already have: the weak modules come out, the rest are tested and rebalanced, and the pack goes back in. It's a real option for the right car and the wrong choice for others.

What this includes

Module-level testing rather than a single pass/fail on the whole pack
Straight answer on whether your pack is a good candidate
Cooling system addressed at the same time — it's usually part of the story
Different warranty terms than replacement, stated up front

What reconditioning actually does

A Toyota or Lexus nickel-metal hydride pack is a series of modules wired together. The pack is only as strong as its weakest link, so a pack can fail because two or three modules have degraded while the rest are still serviceable.

1The pack comes out and is disassembled down to individual modules.
2Each module is tested — capacity, internal resistance, and how it holds voltage under load.
3Weak modules are removed and replaced with tested modules matched to the rest of the pack.
4The pack is charged, discharged and rebalanced so the modules start life together at the same state of charge.
5Bus bars, connectors and the case are cleaned and inspected; corroded hardware gets replaced.
6The pack goes back in, the system is reset and the car is road tested.

Reconditioning is not a “reset”

Clearing codes or doing a forced charge/discharge cycle without opening the pack is not reconditioning. If a price sounds too good, ask whether the pack is being opened and tested at module level at all.

When reconditioning tends to make sense

The failure is clearly concentrated — a small number of blocks are dragging down a pack that is otherwise in reasonable shape.
The rest of the vehicle is sound and you plan to keep it a few more years.
You are trying to keep the car on the road on a tighter budget and understand the trade-off in expected service life.
The pack has a good cooling history: clean intake, working fan, no evidence of chronic overheating.
You want a lower up-front cost — reconditioning carries the same warranty terms as our packs.

When replacement is the better call

The whole pack has aged evenly — every module is tired, so swapping a few just moves the failure a few months down the road.
There is evidence of chronic overheating, water intrusion, corrosion or rodent damage inside the pack.
The pack has already been reconditioned once and has failed again.
You drive a lot of miles, tow, or need the highest confidence for a long commute across the Valley.
The difference in cost is small enough that the longer warranty on a replacement pack is the better value.

We'll tell you when reconditioning is the wrong answer

If the data says replace, that's what we'll recommend. We won't take your money for a repair we expect to fail.

Reconditioning vs. replacement at a glance

	Reconditioning	Replacement
Up-front cost	Lower	Higher
Expected service life	Shorter, and more variable	Longer, more predictable
Warranty	Shorter term — see our warranty page for current terms	Longer term — see our warranty page for current terms
Best for	Concentrated failure, sound vehicle, shorter horizon	Even ageing, high miles, long horizon
Risk	Remaining original modules are still ageing	Lower, assuming the cooling issue is also fixed

Frequently asked questions

Is a reconditioned hybrid battery worth it?

For the right car, yes — a concentrated failure in an otherwise healthy pack is exactly what reconditioning is for. For a pack where every module is equally tired, it's usually false economy. The module test data tells us which one you have.

How long does a reconditioned hybrid battery last?

We won't give you a number. It depends on how much life is left in the modules that stayed in the pack, how the car is driven, and how well the cooling system works. The written warranty is the commitment you can rely on.

Can you recondition a battery that's already been rebuilt once?

Sometimes, but a pack that has failed after a previous rebuild is usually telling you something — either the underlying cooling problem was never fixed, or the remaining modules were already too far gone. We'd want to see the test data before recommending it.

Do you fix just one bad cell?

Toyota and Lexus NiMH packs are serviced at module level, not single cell. Replacing one module in a pack full of tired ones rarely holds up, which is why the whole pack gets tested rather than just the block the code pointed at.
