Asian B and D case batteries are taller (around 225 mm) and narrower: 127-129 mm for B cases and 173 mm for D cases. ## Dimensions by case size | Case | DIN equivalent | Dimensions (L × W × H) | Base hold-down | Varta in this case size | See batteries | |---|---|---|---|---|---| | L0 | H3 | 175 × 175 × 190 mm | B13 | Varta A16, Varta B36 | L0 car batteries | | L1 | H4 | 207 × 175 × 190 mm | B13 | Varta A9, Varta B19, Varta B20, Varta C22, Varta C30 | L1 car batteries | | L2 | H5 | 242 × 175 × 190 mm | B13 | Varta A8, Varta C14, Varta C15, Varta D15, Varta D24 | L2 car batteries | | L3 | H6 | 278 × 175 × 190 mm | B13 | Varta A7, Varta E11, Varta E12, Varta E13, Varta E44 | L3 car batteries | | L4 | H7 | 315 × 175 × 190 mm | B13 | Varta A6, Varta F16, Varta F19, Varta N80 | L4 car batteries | | L5 | H8 | 353 × 175 × 190 mm | B13 | Varta A5, Varta F6, Varta G3, Varta H3, Varta N95 | L5 car batteries | | L6 | H9 | 394 × 175 × 190 mm | B13 | Varta A4, Varta I1 | L6 car batteries | | LB1 | T4 | 207 × 175 × 175 mm | B13 | Varta A17, Varta B18, Varta C6 | LB1 car batteries | | LB2 | T5 | 242 × 175 × 175 mm | B13 | Varta C11, Varta D21, Varta D59 | LB2 car batteries | | LB3 | T6 | 278 × 175 × 175 mm | B13 | Varta D54, Varta E9, Varta E38, Varta E43 | LB3 car batteries | | LB4 | T7 | 315 × 175 × 175 mm | B13 | Varta E46, Varta F17, Varta F18 | LB4 car batteries | | LB5 | T8 | 353 × 175 × 175 mm | B13 | Varta F5 | — | | B19 | — | 187 × 127 × 227 mm | B00 | Varta A14, Varta A15 | — | | B24 | — | 238 × 129 × 227 mm | B00 | Varta A11, Varta B31, Varta B32, Varta B33, Varta B34 | B24 car batteries | | D23 | — | 232 × 173 × 225 mm | B00 | Varta D47, Varta D48, Varta N65 | D23 car batteries | | D26 | — | 260 × 173 × 225 mm | B01 | Varta E23, Varta E24, Varta N72 | D26 car batteries | | D31 | — | 306 × 173 × 225 mm | B01 | Varta G7, Varta G8, Varta N85 | D31 car batteries | Dimensions from our product datasheets; DIN equivalent and hold-down code from VARTA's technical datasheets. The hold-down code identifies the ledge at the base that secures the battery: it must match your current battery. ## L and LB cases: the European sizes - **L (H in the DIN standard):** 175 mm wide and 190 mm high. The most common in European cars: the [Varta E11](https://bateriasonline.es/en/varta-e11) and [Varta E44](https://bateriasonline.es/en/varta-e44) are L3 (H6), the [Varta D24](https://bateriasonline.es/en/varta-d24) is L2 (H5) and the [Varta C22](https://bateriasonline.es/en/varta-c22) is L1 (H4). - **LB (T in the DIN standard):** the same width and length as the L with the same number, but 15 mm lower (175 mm). For example, the [Varta E38](https://bateriasonline.es/en/varta-e38) and [Varta E43](https://bateriasonline.es/en/varta-e43) are LB3, the [Varta D59](https://bateriasonline.es/en/varta-d59) is LB2 and the [Varta B18](https://bateriasonline.es/en/varta-b18) is LB1. - An **R** after the case (L3R, H6R) means reversed polarity: the positive on the left, as on the [Varta E12](https://bateriasonline.es/en/varta-e12). ## B and D cases: the Asian sizes Many Japanese and Korean cars use JIS-standard cases: B cases (B19, B24) are narrow and tall, and D cases (D23, D26, D31) are 173 mm wide. The number roughly gives the length in centimetres. They usually have a different hold-down from European batteries (code B00 or B01 on the manufacturer's datasheet) and sometimes thinner terminals, so it is not a good idea to replace them with an L case even if the capacity matches. ## How to find out which case your car uses - Look for the reference (E11, D24…) or the 9-digit ETN code on the battery label and find it in [Varta, Bosch, Exide and Tudor car battery equivalents table](https://bateriasonline.es/en/varta-bosch-exide-tudor-car-battery-equivalents). - If you cannot read it, measure the length, width and height (including the terminals) and compare them with the table. - Check which side the positive terminal is on, with the terminals facing you. - Check how it is held in place: with a clamp on the base ledge or with a frame over the top.

It is the size of the Varta E11, E44, N70 and A7, and corresponds to the H6 case in the DIN standard. ### What is the difference between an L3 and an LB3 case? The height: the L3 is 190 mm and the LB3 175 mm. Length and width are the same. Only choose an LB if your original battery is LB or if there is no room for extra height. ### Can I fit an L4 instead of an L3? Only if there is room: the L4 is 315 mm long, 37 mm more than the L3. Before buying, measure the space and check that the hold-down clamp still reaches. ### Can Asian D23 or D26 batteries replace an L2 or L3? Not as a general rule. D cases are taller (225 mm) and slightly narrower (173 mm), and they have a different hold-down. Always look for a battery with the same case as the original. ### What does the R in L3R or H6R mean? That the polarity is reversed compared with the standard layout: the positive is on the left. The Varta E12 is an L3R; the E11, with the positive on the right, is an L3. --- *bateriasonline.es — Batteries and accessories · 2026-11-11*
