Aside from providing vital knowledge about this matter, our article will also give you plenty of information that you have to know more about 26r batteries. Some awesome brands are also included here to consider in choosing the perfect ones for your vehicles. 

BCI Group 26 & Group 26R Batteries Dimensions 

BCI Group 26 and Group 26R batteries are relatively similar when you compare their dimensions, terminal types, and features. The only basic difference between the two types of batteries is the terminal orientation. Just BCI Group 26 has a negative terminal to the right and positive to the left. Alternatively, BCI Group 26R has the negative terminal to the left and positive to the right in most cases. 

The nominal dimensions of the group 26 and group 26R batteries are 8 3/16″ X 6 13/16″ X 7 3/4″ or 20.8 CM X 17.3 CM X 19.7 CM.  The 6 13/16 inch (17.3 CM) length adds the flanges.  Again, a 7 ¾ inch (19.7 CM) height adds the Flat Classical top. The average weight of the most lead-acid batteries is 28 to 30 pounds or 12.7 to 13.6 kg. 

Here are the electrical and mechanical specifications of the group 26r batteries. 

Specifications:

The most common thing is the battery power depending on the nominal voltage and capacity. Fortunately, maximum group 26 and 26R batteries come with 12 volts that is strong & standard for vehicles. On the other hand, capacity measures the number of electrons provided by a battery. 

Remember, the capacity of a battery, however, varies on the brands and the manufacturers. Measuring the capacity number of watt-hours or amp-hours. And, it provides information about how much electrical power is supplied to start the engine. 

You can also measure the instant hours using amp-hours and Cold Cranking Amps. We already showed the group 26R batteries provide at least 235 CCA and a maximum amount of 540 CCA. 

Moreover, the deep cycle capacity is measured in Amp Hours or Reserve Capacity Minutes. These batteries provide from 60 to 80 reserved capacity minutes. Want to compare the several battery features, CCA, RC? A cross-reference chart can help you find an overall idea about group 24, 26, 26r, 48, or more.
