Toyota Hybrid Generations: Which Pack Fits Which Year
The model year is not enough to pick a hybrid battery. Three Alphards, three different packs. How to read the generation code and get the right…
What a 3-Year Hybrid Battery Warranty Actually Covers
A warranty is only worth what it pays for. What our 3-year / 100,000 km cover includes, what it excludes, and why we replace a module…
Why Hybrid Batteries Struggle in Cold Weather (and What Actually Helps)
Cold reduces usable capacity, and a worn pack fails first when the temperature drops. What is normal winter behaviour and what means the pack is finished.
NiMH or Li-ion for the Same Car? How to Choose a Replacement Pack
Both chemistries fit the same battery bay on most Toyota and Lexus hybrids. What actually differs — weight, capacity, discharge rate, cold behaviour and price.
How to Test a Hybrid Battery Before You Buy a Replacement
Three checks anyone can do before spending money on a hybrid battery — block voltages, EV mode behaviour, and the two free fixes people miss.
Solid-State Hybrid Cells: What Is Real and What Is a Roadmap
3 V per cell, 210 Wh/kg, 30,000 cycles — what our solid-state programme is targeting, and why you cannot order it yet.
Bipolar NiMH Modules: 2× the Power, 1.5× the Energy, 300% Better Cooling
A bipolar stack shares plates between cells, so the cooling path is direct and the packaging disappears. What it changes: 2× power, 1.5× energy density, 300%…
Side Current Collection: 50% More Power from the Same Chemistry
Why a single tab limits a NiMH cell, and how collecting current from both sides of the can raises power density by 50% — with the…
Capacitor-Type NiMH Cells: Materials, Manufacturing and Why They Last 10,000 Cycles
What is inside a capacitor-type NiMH cell, how it is built, and why it holds more than 10,000 cycles at 10C — with the comparison against…
