In almost all respects, C2 and C4 batteries are the same. Both are lead-acid batteries with flooded cells. They both have the same 12-volt rating and can be used in any application that calls for a lead-acid battery. The only difference is in their size; C2 batteries are about half the size of C4s. Here’s a look at the
key differences between these two types of batteries: There are two types of photosynthesis- C3 and C4. Both process involve the conversion of light energy into organic matter, such as glucose. The difference between the two is in how they capture carbon dioxide gas from the atmosphere. In C3 plants, the first step of photosynthesis takes place in the chloroplasts of mesophyll cells. These cells have many small vacuoles that help to keep the cell turgid (swollen). When CO2
enters these cells, it diffuses into the stroma, where it reacts with RuBP to form 2 molecules of 3-PGA. In contrast, C4 plants have a special type of leaf anatomy called Kranz Anatomy. In these leaves, there are two types of photosynthetic cells- bundle sheath cells and mesophyll cells. The bundle sheath cells surround the vascular bundles (the xylem and phloem) and have few or no chloroplasts. The mesophyll cells are located outside of the vascular bundles and have many
chloroplasts. The initial steps of photosynthesis in C4 plants take place in mesophyll cells, just like in C3 plants. However, instead of diffusing directly into the stroma, CO2 first binds to a four-carbon compound called PEP (Phosphoenolpyruvate). This reaction creates a molecule called oxaloacetate which quickly breaks down to release 2 molecules of 3-PGA. The 3-PGA then diffuses into bundle sheath cells where it is converted into G6P (glucose 6 phosphate). This process uses up ATP and
NADPH from the light reactions stage. Are C2 Batteries the Same As C? C2 batteries and C batteries are not the same. C2 batteries are a type of
button cell battery, while C batteries are cylindrical alkaline batteries. C2 batteries are generally used in small electronic devices, such as watches and calculators. They have a diameter of 11.6 mm and a height of 3.8 mm. C batteries, on the other hand, have a diameter of 26-28 mm and a height of 50-60 mm. The voltage for both types of battery is different as well – C2 batteries have 1.5 volts, while C batteries have 1.2 volts. In terms of capacity, C2 batteries can store about
500 mAh of charge, while C batteries can store around 3500-4000 mAh. Credit: www.ebay.com Conclusion C2 and C4 batteries are both types of lead acid batteries. Lead
acid batteries work by using a chemical reaction to create an electrical current. The main difference between C2 and C4 batteries is the size of the cells. C2 batteries have smaller cells, which means they can’t store as much power as C4 batteries. However, C2 batteries are typically lighter and more portable than C4 batteries.
So, which type of battery is right for you? It depends on your needs. If you need a battery with a long lifespan, then a C4 battery would be a better choice.
However, if you need a battery that’s small and easy to carry around, then a C2 battery would be a better option.Are C2 Batteries the Same As C ?
What are C Batteries?
The C battery is a standardized dry cylindrical cell defined by its roughly 50mm length and 26.2mm diameter. They can boast capacities upwards of 8,500 mAh, and are typically used in mid-drain appliances, large toys, and some searchlights. They also go by the names R14 and LR14.

Are there rechargeable C batteries?
Yes, rechargeable C batteries use NiMH (nickel-metal hydride) or NiCd (nickel-cadmium) chemistries and have a 1.2V voltage compared to the typical 1.5V. Always check with your device's user manual to see if a battery voltage or chemistry is compatible.
Do C batteries expire?
Yes, all batteries eventually expire. C-cell batteries have a range of shelf lives between 3 and 25 years, wholly dependent on the battery's chemistry and storage conditions. We list the rated shelf life on all our product listings when available so you can make an informed choice when buying spares or bulk cells. For more information, check out our battery expiration guide!
Are C cells and LR14/R14 batteries the same?
Yes, they are the same size of battery with different names. ANSI calls C-cells '14', and IEC standards call it 'R14'. The 'LR' in LR14 designates an alkaline chemistry.
Can C batteries replace D batteries?
No, unless you own a trusted battery-adapter sleeve specifically designed for that purpose. C and D cells have very different dimensions (C batteries are 26.2mm x 50mm, while D batteries are 22.3mm x 61.5mm). Do NOT use DIY (do-it-yourself) tricks and guides to modify batteries, as it can have dangerous results.
What C battery brand lasts the longest?
We don't play favorites at Battery Junction, and runtimes are often dependent on your device's battery drain and operating temperature. Typically, batteries with larger capacities (mAh) have longer overall runtimes. C cells tend to max out at 8,500 mAh, and you can filter our wide-selection of batteries by 'Capacity (mAh)'.
Do you offer bulk-pricing on C batteries?
Yes! A large selection of our batteries can be bought in bulk, letting you take advantage of huge discounts! You can filter our selection of batteries by bulk-eligibility, fill out a wholesale request form, or directly contact a member of our sales team now via phone or email!
