The difference between the two batteries lies in their ability to store energy. The Group 24F battery stores more energy because of its high-capacity rating. On the other hand, the Group 35 battery stores less energy because it is rated at a lower capacity.
Understanding Different Battery Sizes
To understand the different battery sizes, let’s first review a few key concepts:
How Do I Know What Size Battery I Need?
The size of your battery bank depends on how much energy you need to run your appliances; your battery system’s energy capacity should always be greater than your energy demand.

Final Thoughts
When it comes to sizing your battery bank, there are different types of batteries and capacities to choose from. Moreover, it can be confusing to determine what battery size you need for your specific needs.
What is the diameter of an AA battery?
Same diameter as AA battery, used in small electronics, including electric shaver. 14.5 × 25.0 (max.) Same diameter as AA battery, used in small electronics, including pulse oximeters, as well as use in some computer models (such as most pre-Intel Macintosh models and some older IBM PC compatibles) as the CMOS battery.
How much does a lithium battery weigh?
Commonly used on computer motherboards as nonvolatile BIOS memory and real-time clock (RTC) backup batteries. Weighs around 2.9 g.
How long is a lithium ion battery?
Many are also available with internal protection circuits that can increase their physical length; for example, an 18650 is around 65 mm (2.56 in) long, but may be around 68 mm (2.68 in) long with an internal protection circuit. Some such circuits increase cell diameter instead. The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry.
What does CR mean in lithium?
The IEC prefix "CR" denotes lithium manganese dioxide chemistry. Since LiMnO 2 cells produce 3 volts there are no widely available alternative chemistries for a lithium coin battery. The "BR" prefix indicates a round lithium/carbon monofluoride cell. See lithium battery for discussion of the different performance characteristics. One LiMnO 2 cell can replace two alkaline or silver-oxide cells.
How much air does a hearing aid battery need?
Each cell needs around 1 cc of air per minute at a 10 mA discharge rate. These cells are commonly used in hearing aids. A sealing tab keeps air out of the cell in storage; a few weeks after breaking the seal the electrolyte will dry out and the battery becomes unusable, regardless of use.
What is a full battery?
The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per cell) and the number of cells in the battery. For example, a CR123 battery is always LiMnO 2 ('Lithium') chemistry, in addition to its unique size.
How many volts does a lithium battery have?
All these lithium cells are rated nominally 3 volts (on-load), with open-circuit voltage about 3.6 volts. Manufacturers may have their own part numbers for IEC standard size cells. The capacity listed is for a constant resistance discharge down to 2.0 volts per cell.
Group U1 Alternatives and Closest Battery Groups by Dimensions
These groups have the same dimensions and performance but can have different terminal post types, post locations, and polarity.
How to Get 24 Volts from 12V of a U1 Battery Group
If you need 24 Volts, you can connect two group U1 batteries in series to double the voltage. The voltage of a series connection is equal to the sum of the voltages of all its batteries. If one 12V lead-acid battery is connected to another 12V lead-acid battery, you have 24V total power output.
Increasing a Capacity of U1 Batteries with a Parallel Connection
If you need to increase current capacity and reduce charging time, connect batteries in parallel. When group U1 batteries are in parallel, their voltage is equal to the voltage of one battery, while current capacity equals to the sum of all its battery capacities.
What is Battery Group Size?
When purchasing a battery, you will see a series of numbers and letters in the name. These numbers and letters are the BCI group size of the battery. BCI stands for Battery Council International. This is a trade association that includes manufacturers, recyclers, distributor, and retailer organizations that supply original and after-market batteries.
What is the best source of information to find the recommended battery group size and specifications?
The best source of information to find the recommended battery group size and specifications is your Owner’s Manual.
How many volts does a car battery hold?
Most car batteries are labeled as 12 volts. However, they can hold closer to 15 volts due to power from the alternator. When the car is running and the alternator is charging, the voltage (electrical pressure) should measure between 13.7 to 14.7 volts. An actual reading of 12.4 volts when the car is running means that the battery is only at about 75% of its optimal capacity. Your car will still run, but you need to get the battery checked because it can be a sign that it needs to be replaced soon. If it falls below 10.5 volts, your car probably will not start, but some can go as low as 9.5 volts and still seem fine.
