JIS N150 vs N200: Which Heavy-Duty Truck Battery?¶
TL;DR — N150 (145G51) is the standard heavy-duty JIS battery at 135Ah / 900A CCA; N200 (190H52) is the larger, more powerful option at 200Ah / 1100A CCA. Choose N200 when you need maximum cranking power or cold-climate reliability and your tray fits it; otherwise N150 is lighter, cheaper and enough for most heavy trucks.
Key Takeaways¶
- N200's capacity jump doubles its CCA jump — 48% more capacity (200Ah vs 135Ah) but only 22% more CCA (1100A vs 900A), so the N200 mainly buys runtime and cold-weather margin, not proportionally more starting punch.
- Tray depth is the real decision gate — the N200 is 278mm deep versus the N150's 222mm, so fit often overrules the electrical spec before you even compare CCA.
- 900A CCA covers most heavy diesels — if the engine starts reliably on the 145G51's 900A, paying for the 190H52's 1100A just adds weight and cost you never use.
- Both are 12V — 24V trucks need a pair — wire two N150 or two N200 in series for 24V, and always replace the pair together.
- Reserve capacity widens the gap further — 320 min (N200) vs 220 min (N150) matters more than CCA if the truck idles with heavy electrical loads.

What "N150" and "N200" Mean¶
In the JIS (Japanese Industrial Standards) system, large commercial batteries are identified by a model code where the number roughly tracks size and capacity. The "N" prefix denotes a large heavy-duty battery. DINWEYS manufactures these as the 145G51 and 190H52 models.
| Specification | 145G51 (N150) | 190H52 (N200) |
|---|---|---|
| Voltage | 12V | 12V |
| Capacity (C20) | 135 Ah | 200 Ah |
| CCA (SAE) | 900 A | 1100 A |
| Reserve capacity (RC) | 220 min | 320 min |
| Dimensions (L×W×H) | 508 × 222 × 212 mm | 520 × 278 × 220 mm |
| Terminal | JIS type A (large post) | JIS type A (large post) |
| Typical use | Heavy trucks, buses | Largest trucks, buses, generators |

Side-by-Side Comparison¶
Capacity and CCA¶
The N200 delivers about 48% more capacity (200Ah vs 135Ah) and 22% more CCA (1100A vs 900A) than the N150. This makes the N200 the better choice for:
- Large-displacement diesel engines (bigger starter current draw)
- Cold / Arctic climates (where CCA matters most)
- Vehicles with heavy electrical loads when idling
Size and Weight¶
The N200 is deeper (278mm vs 222mm) and heavier than the N150. Before choosing, confirm:
- Your battery tray dimensions
- The hold-down bracket compatibility
- That the added weight is acceptable for your application
The dimensions hide a less obvious point: the N200's extra volume buys more than its share of capacity. The N150 displaces roughly 23.9 L (508×222×212 mm) and the N200 roughly 31.8 L (520×278×220 mm) — a 33% larger case. But capacity grows 48% (135Ah → 200Ah), so the N200's energy density works out about 11% higher (≈5.6 vs ≈6.3 Ah/L). The N200 is not simply a bigger N150 — it is a slightly more compact battery per amp-hour, which matters when tray space is fixed and every amp-hour counts.
Cost¶
The N150 is the more economical choice. If your engine starts reliably on 900A CCA, the N150 gives you the same chemistry and build quality at a lower cost and weight.
How to Choose¶
| Question | Choose N150 (145G51) | Choose N200 (190H52) |
|---|---|---|
| Tray depth | Up to ~222mm | Up to ~278mm |
| Engine size | Standard heavy diesel | Large / high-compression diesel |
| Climate | Temperate / hot | Cold / Arctic |
| CCA need | Up to ~900A | Up to ~1100A |
| Budget | Lower | Higher |
Confirm against your manual
Always confirm the required group size and CCA in your vehicle manual. The wrong physical size cannot be safely installed, regardless of electrical rating.
24V Systems¶
Both the N150 and N200 are 12V batteries. In 24V heavy-truck systems, two are wired in series — for example two N200 units for maximum 24V cranking power. Always replace the pair together. See the 12V vs 24V guide.

Frequently Asked Questions
What is the difference between JIS N150 and N200?
The N150 (model 145G51) has 135Ah capacity and 900A CCA in a 508×222×212mm case. The N200 (model 190H52) is larger and more powerful with 200Ah and 1100A CCA in a 520×278×220mm case. N200 suits larger engines and colder climates.
Is N200 always better than N150?
Not necessarily. N200 has more CCA and capacity, but it is physically larger and heavier. If your battery tray only fits N150, or your engine does not need 1100A CCA, N150 is the correct choice.
Are N150 and N200 interchangeable?
No. They have different dimensions (508×222×212mm vs 520×278×220mm) and terminal positioning. A battery must physically fit the tray — always match the group size.
What CCA does an N150 provide?
The DINWEYS 145G51 (N150) provides 900A CCA (SAE) — suitable for many heavy-duty diesel engines.
What CCA does an N200 provide?
The DINWEYS 190H52 (N200) provides 1100A CCA (SAE) — the highest in the JIS truck range, suited to large diesel engines and cold climates.
