description: Decoding JIS and DIN battery model numbers — what 145G51, 190H52, 58827 and 60038 mean, and how the numbering systems work. type: article date_published: 2026-08-30 date_modified: 2026-08-30 faq: - q: What does the N in N150 mean? a: "N" is a JIS battery size class for larger heavy-duty batteries. N150 and N200 are widely used JIS heavy-duty truck battery designations. The number broadly indicates size, but the underlying JIS type number (like 145G51 or 190H52) is the precise identifier. - q: What does 145G51 mean in a JIS battery number? a: JIS type numbers encode the battery's dimensions, terminal layout and performance class. The leading digits relate to the physical size and performance, while the trailing letter/number identifies the terminal and case configuration. The full type number is the authoritative identifier. - q: What does DIN88 or DIN100 mean? a: DIN88 and DIN100 are common European shorthand for DIN-standard heavy-duty batteries, roughly tied to capacity class. The precise identifier is the full DIN/EN type number such as 58827 or 60038. - q: Why are there two numbers for the same battery? a: Manufacturers list both a market shorthand (like "N150" or "DIN88") and a formal type number (like 145G51 or 58827). The formal type number is what actually defines the physical and electrical specification. - q: How do I make sure I order the right battery? a: Read the full type number and dimensions from your existing battery or manual, and confirm voltage, CCA, terminal type and polarity. The type number — not the shorthand — is the exact specification.

Decoding JIS & DIN Battery Model Numbers

TL;DR — Battery model numbers look cryptic, but they encode real information. JIS heavy-duty batteries use type numbers like 145G51 (sold as "N150") and 190H52 ("N200"); DIN batteries use numbers like 58827 ("DIN88") and 60038 ("DIN100"). The full type number is the authoritative spec — the shorthand is just a convenient name.

JIS: The "N" Shorthand vs the Type Number

In JIS markets, heavy-duty truck batteries are often sold by a short "N" name:

Market shorthand JIS type number Capacity CCA
N150 145G51 135 Ah 900 A
N200 190H52 200 Ah 1100 A

The "N" name is a broad size class. The type number (145G51, 190H52) is the precise identifier — it defines the exact dimensions, terminal layout and performance class.

DIN: The "DIN88" Shorthand vs the Type Number

European heavy-duty batteries follow the same pattern:

Market shorthand DIN type number Capacity EN rating
DIN88 58827 88 Ah 800 A EN
DIN100 60038 100 Ah 870 A EN

Why the Type Number Matters

The type number encodes the physical and electrical specification. Two batteries that look similar in a shorthand name may have different dimensions or terminal layouts. When ordering or specifying:

  1. Read the full type number from the existing battery label
  2. Confirm dimensions (the N200 is physically larger than the N150)
  3. Confirm voltage, CCA, terminal type and polarity
