DIN88 vs DIN100 Heavy-Duty Truck Battery
The DIN100 (60038) is simply a longer version of the DIN88 (58827) — same 175mm width, same 190mm height, but 40mm more case length. That extra length buys more capacity and stronger cold cranking, but only if your truck's tray has the room for it.
Direct Answer
DIN88 (58827) = 12V, 88Ah, 800A EN, 150min RC, 353×175×190mm. DIN100 (60038) = 12V, 100Ah, 870A EN, 170min RC, 393×175×190mm. Both are EN 50342-1 flooded batteries with European conical (T1) terminals, available in flooded, EFB and AGM. The only physical difference is case length — the DIN100 is 40mm longer, so it needs a longer tray than the DIN88.
Key Takeaways
- "DIN88" and "DIN100" are size classes, not ratings — the model code (58827 / 60038) carries the actual capacity and cold-cranking figure.
- The upgrade is length-only — DIN100 keeps the DIN88's 175mm width and 190mm height; it is just 40mm longer, unlike a JIS N150→N200 jump where width is the blocker.
- EN cold-cranking is not JIS CCA — 800A EN is measured to EN 50342-1 and cannot be compared against a JIS or SAE figure.
- Size and technology are separate decisions — both sizes come in flooded, EFB and AGM; don't let the size choice force a technology choice.
- Check the tray length, not the width — a tray that holds a DIN88 will usually hold a DIN100 only if there is 40mm of spare length.
Specification Comparison
| Specification | DIN88 (58827) | DIN100 (60038) | What it means |
|---|---|---|---|
| Voltage | 12V | 12V | Identical — both are single 12V batteries |
| Capacity (C20) | 88 Ah | 100 Ah | DIN100 stores ~14% more energy |
| Cold-cranking (EN 50342-1) | 800 A | 870 A | DIN100 gives a stronger cold start |
| Reserve Capacity (SAE J537) | 150 min | 170 min | DIN100 = +20 min engine-off buffer |
| Dimensions (L×W×H) | 353×175×190 mm | 393×175×190 mm | Same width & height — DIN100 is 40mm longer |
| Terminal | European conical (T1) | European conical (T1) | Same terminal type, left positive |
| Technology | Flooded / EFB / AGM | Flooded / EFB / AGM | Same technology options |
| Typical application | Standard European trucks, buses, cold climates | Larger European trucks, high electrical loads | DIN100 for the heavier duty |
Figures are DINWEY first-party specifications (EN 50342-1 cold-cranking). Third-party DIN88 CCA commonly ranges ~800–850A and height varies (190mm vs some 174mm builds) by manufacturer — always compare within one standard and confirm against the specific datasheet.
What Is the Difference?
The DIN88 and DIN100 are the two core DIN-format heavy-duty battery classes for European commercial vehicles. Both are 12V batteries with European conical (T1) terminals, built to the EN 50342-1 cold-cranking standard, and both are offered in flooded, EFB and AGM construction.
The difference is case length and the output that comes with it. The DIN100 is 40mm longer (393mm vs 353mm) but shares the exact same width (175mm) and height (190mm). That longer case holds more plate area, which is why the DIN100 delivers more capacity (100Ah vs 88Ah), stronger cold cranking (870A vs 800A EN) and more reserve capacity (170min vs 150min).
Why the Difference Matters
Tray Length
The DIN100 needs 40mm more length than the DIN88. In the tight battery tray of a European truck, that extra length — not width or height — is what decides whether it fits.
Cold-Start Margin
870A vs 800A EN is a modest but real gain for the largest engines and the coldest mornings. If the engine is marginal on cranking, the DIN100 is the safer bet.
Electrical Load
The extra 20 minutes of reserve capacity helps when a truck runs telematics, lighting or lift-gate loads with the engine off.
Are They Interchangeable?
Only if the tray has spare length. Because width and height are identical, the only fit constraint is the 40mm length difference. A DIN100 will not drop into a tray sized exactly for a DIN88 without 40mm of free length and a hold-down that reaches the longer case.
The reverse is easier: a DIN88 will usually fit a tray built for a DIN100 (leaving 40mm of empty space, which may need a spacer or block), but it delivers less capacity and cranking, so only step down if the DIN88 meets your engine's requirement.
Buyer Decision Guide
| Your situation | Choose | Why |
|---|---|---|
| Standard European truck, tray sized for DIN88 | DIN88 (58827) | Fits the tray; 800A EN meets normal diesel cranking |
| Larger truck / high electrical load / cold climate | DIN100 (60038) | 100Ah and 870A EN with 170min RC for heavy duty |
| Tray has 40mm spare length and wants more power | DIN100 (60038) | Length-only upgrade — no width/height change |
| Existing DIN88 battery, working fine | DIN88 (58827) | Direct replacement — no tray change needed |
| Wants maintenance-free but tray is DIN88-sized | DIN88 AGM | Keep the size, upgrade the technology to AGM |
| 24V system, replacing a pair | Two identical | Two DIN88 or two DIN100, never mixed |
What to Check Before Ordering
- Tray length — the DIN100 is 40mm longer than the DIN88; width and height are the same.
- Terminal orientation and cable reach (European conical T1, left positive).
- Engine cranking requirement — compare within EN 50342-1, not against JIS or SAE figures.
- Whether the vehicle is 12V or 24V (two batteries in series).
- Technology choice — flooded, EFB or AGM — independent of the DIN88/DIN100 size decision.
Verification note: Specifications vary by manufacturer. The DIN88 and DIN100 figures above are DINWEY first-party specifications. Always confirm the exact group size, terminal type, polarity and tray dimensions against your vehicle manual before replacement.
Frequently Asked Questions
What is the difference between DIN88 and DIN100?
The DIN100 (60038) is 40mm longer than the DIN88 (58827) — 393mm vs 353mm — with the same 175mm width and 190mm height, giving 100Ah and 870A EN vs 88Ah and 800A EN.
Can I replace a DIN88 with a DIN100?
Only with 40mm of spare tray length. The DIN100 keeps the same width and height but is longer, so it will not fit a tray sized exactly for a DIN88.
Is the DIN100 always the better battery?
No. It is higher-output but longer and heavier. If the DIN88 meets your engine's requirement and fits your tray, it is the correct and more economical choice.
Are DIN and JIS cold-cranking ratings comparable?
No. DIN uses EN cold-cranking (EN 50342-1), a different test from JIS CCA or SAE CCA. An 800A EN rating is not comparable to an 800A JIS figure.
Does the DIN88 or DIN100 come in AGM?
Both are available in flooded, EFB and AGM. The size decision (DIN88 vs DIN100) is separate from the technology decision.
