EnerCellix builds brand-new replacement hybrid battery packs for Toyota, Lexus, Honda and GM hybrid vehicles — complete assemblies that drop into the original battery housing, in Ni-MH and Li-ion, from 100.8 V to 288 V.
Who is behind EnerCellix
EnerCellix is the hybrid and EV battery brand of Polytone Technology Co., Ltd., a Shenzhen battery manufacturer founded in 2010. The company has been building rechargeable battery packs for over 15 years and now supplies hybrid replacement packs to workshops, distributors and individual owners worldwide.
What we cover, in numbers you can check
Our catalogue currently covers 67 hybrid models from 10 manufacturers, in 9 voltage specifications from 100.8 V to 288 V. Every figure on this page can be checked against the fitment index or the price by pack size table — count them yourself.
What we actually sell
A complete pack, not loose cells. The customer removes the original assembly from its housing and fits ours in its place; the cells inside are our construction choice, which is why a car that left the factory with Ni-MH can run a Li-ion pack and the reverse.
What is in the pack
- Brand-new Grade-A cells — never salvaged, never re-cased.
- Capacity, internal resistance and open-circuit voltage matched before assembly, so the modules age together rather than one drifting ahead of the rest.
- Independent serial number with QR traceability — production date, grading parameters and test log per module.
- Every pack discharge-tested and shipped with a capacity and resistance report.
Chemistry options
For most vehicles we build both Ni-MH and Li-ion versions of the same voltage. Ni-MH takes repeated high-rate cycling and extreme temperatures better; Li-ion is lighter and, on our current pricing, cheaper for the same module count. Which one suits a particular car is an engineering question, not a marketing one — the comparison is here.
Sodium-ion, too
EnerCellix sits inside a battery manufacturer that has been building rechargeable packs since 2010, and sodium-ion is part of that wider business — it is already supplied into industrial, rail and stationary-storage projects where its cold-weather behaviour and cycle life matter more than energy density.
The hybrid replacement catalogue on this site is Ni-MH and Li-ion today. Sodium-ion packs for hybrid vehicles are quoted per project rather than listed as stock items — if you are specifying for a very cold market or a fleet with an unusual duty cycle, send us the requirement and we will tell you honestly whether sodium-ion is the right answer yet.
Fitment before payment
The same model year can carry two different packs, and three Alphard generations use three different architectures. Before dispatch we confirm the pack against the VIN or chassis code. If we confirm the fitment and the pack does not fit, we take it back and cover the return freight.
Warranty
3 years or 100,000 km, whichever comes first, against manufacturing defects. If a module fails we replace that module rather than the whole pack — a pack rarely fails as a unit, and changing the single failed module is what restores the car. The replacement module is supplied free; freight in both directions is not covered.
Shipping
Hybrid packs ship as Class 9 dangerous goods with the required transport documentation. Selected routes are DDP, with duties and taxes included in the price you see; on other routes the import bill is settled separately. In-stock packs dispatch in 3 business days.
Where we are
Office: Floor 5, Block A & E, Donghaiwang Industrial District, Yangmei, Longgang District, Shenzhen, Guangdong, China.
Manufacturing is carried out across three sites in mainland China — Hunan, Dongguan and Guangzhou — each tooled for a different part of the process. Final assembly, capacity testing and packing are completed before any pack is released for export.
We supply trade customers, workshops and distributors as well as individual owners, and we ship worldwide.
What we do not do: we do not operate an installation network and we do not service vehicles. A hybrid battery swap is a high-voltage job — we recommend a qualified hybrid workshop. An incorrect installation is not covered by the warranty.
