Battery Guides

Battery size codes, technologies and selection criteria for automotive, pickup, truck and bus applications.

• Deep Cycle Battery Guide

  How deep cycle batteries differ from starting batteries, depth of discharge and cycle life, capacity at C5, C10, C20 and C100 rates, and 6 V, 8 V and 12 V packs for golf carts, solar and marine use.

• Forklift Traction Battery Guide

  Traction battery basics for forklifts: 2 V cells and system voltage, C5 capacity, PzS/PzB/PzV cells, tray size and counterweight, REMA and SB connectors, charging, and what to send in an RFQ.

• EV and Hybrid 12 V Auxiliary Battery Guide

  The role of the 12 V auxiliary battery in BEV, HEV and PHEV vehicles, the technologies used, venting for in-cabin and boot installations, and what to check when replacing one.

• Battery Terminal Layout Guide

  How JIS L/R codes, European layouts 0, 1, 3 and 4 and the JIS (S) suffix describe terminal position and post size, and why a reversed layout is a supply error.

• How to Select a Battery by Ah and CCA

  What 20-hour capacity, cold cranking amps and reserve capacity mean under SAE J537, EN 50342-1 and JIS D 5301, and why ratings from different standards cannot be compared directly.

• EFB vs Standard Flooded Batteries

  How an Enhanced Flooded Battery differs from a standard flooded starter battery in construction and testing, when start-stop vehicles require EFB, and what to specify when replacing one.

• N-Series Truck Battery Codes: N50 to N200

  What N50, N70, N100, N120, N150, N200, NS40 and NS60 battery codes mean, how they map to JIS D, E, F, G and H cases, and how they are used in 24 V truck systems.

• DIN and EN Battery Sizes: LN and LBN Guide

  European starter battery sizes LN0 to LN6 and LBN1 to LBN5, B13 bottom hold-downs, terminal layouts 0 and 1, and how DIN and ETN battery numbers are built.

• JIS Battery Size Codes Explained

  How to decode JIS D 5301 battery codes such as 55B24L, 95D31R and 245H52: performance rank, case group, length, terminal position, the (S) suffix and idling-stop codes.

• Truck Battery Selection Guide

  How to select batteries for trucks and buses: 12 V and 24 V systems, series and parallel wiring, JIS, N-series, DIN and BCI sizes, cranking performance, climate and dry-charged supply.

• EFB vs AGM Batteries

  How Enhanced Flooded Batteries and Absorbent Glass Mat batteries differ in construction, charging behavior, heat tolerance and application, and why start-stop vehicles must not be downgraded.

• JIS vs DIN Automotive Batteries

  The practical differences between JIS and DIN/EN batteries: case dimensions, terminal posts, hold-down design, performance ratings and when one can substitute for the other.

• How Automotive Battery Sizes Work

  How to read JIS battery codes such as 55B24L, N-series designations such as N70 and N150, and European DIN/EN codes, and what each code does and does not tell a buyer.
