What Is Battery Group Size 94R?

The Battery Council International (BCI) assigns a group number to each battery. These are the different battery casing dimensions and applications. Group Size 94r is one of them.

There are other group sizes as well, such as Group 24 Batteries, Group 34 Batteries, Group 48 (H6, L3, 66L3) Batteries, Group 65 Batteries and many more. Among them, Group 94R batteries are intended to be maintenance-free and provide a high starting current even in freezing conditions.

You might be thinking, What does 94R battery mean? BCI Group 94R batteries have a serial number of 94 on the BCI size chart and an ‘R’ on the label, indicating that the positive terminal is on the right side of the battery (reversed).

It powers a wide range of onboard equipment, charges quickly, and survives automatic start-stop operations. They’re commonly found on BMW, Mercedes, Audi, Volkswagen, and other manufacturers’ automobiles.

Group 94R Batteries Specifications

  • Battery type: Dual-purpose and Absorbent Glass Mat (AGM);
  • AH Capacity: Ranging from 60 to 76 amp-hours (Ah);
  • Cold Cranking Amp: 750 to 840 CCA;
  • Reserve capacities: 130 RC to 158 RC;
  • Physical measurements: L 12.40 x W 6.90 x H 7.50 inches;
  • Weight on average: 23.6 – 25.8 kg.

Group 94R Batteries Features-To Consider When Buying

When considering the purchase of a Group 94R battery, a few factors should be taken into consideration.

RC Score

If you need 25 amps of electricity for a specified period, this rating tells you how long it will last. Most of the Group 94R batteries have an RC rating of roughly 140 minutes. Delphi BU9094R MaxStart 94R AGM Battery is one of them. When purchasing one of these batteries, this rating is critical. It lays out just how much more weight they can tolerate.

CCA Score

The CCA rating of the battery tells you how much current it can deliver. 94R batteries have a CCA rating of average 620 to 950 amps, respectively. But the average 94r battery has 800 CCA, such as ACDelco Gold 94RAGM have.

A CCA rating of 1000 may give you excellent backup, but it will add to the overall cost of the battery. But it has a longer cycle life and better performance. Opt for a battery that has a CCA rating similar to your existing one. 


It’s important to remember; there is an insufficient amount of space available for the battery. As a result, you’ll need to select a model that’s easy to fit into the available area. If it doesn’t, you’ll have to shell out cash to fix it. The dimensions of a standard 94R battery are L 12.40 x W 6.90 x H 7.50 inches.

Capacity in Nominal

The nominal capacity of Group 94R batteries is typically between 70 and 80 Ah. Anything that happens to be located along that line is more than capable of supplying power to onboard systems for several weeks. Nonetheless, looking at this number may put you at ease.


Battery specialists would always advise you to choose the more expensive solutions available to you if your budget allows it. The rationale for this is that more costly batteries represent better value and more lasting construction materials. ACDelco Gold 94RAGM is the cheapest one I found, providing better service.

In addition, more expensive choices like Powertex Batteries Lithium-Ion LiFePO4, are typically accompanied by a warranty that can last for three or four years. As a result, you will save money over the long term.
