EBL C 1.2V 5000mAh NiMH Rechargeable Batteries

A C battery, also known as a C cell or R14 battery, is a standardized cylindrical battery commonly used in portable electronic devices. It is larger than an AA or AAA battery but smaller than a D battery. Here's an overview of its characteristics:

Electrical Specifications

• Voltage: Typically 1.5 volts for non-rechargeable batteries (alkaline, zinc-carbon) and 1.2 volts for rechargeable types (NiMH, NiCd).
• Capacity: Ranges from 3,800 mAh to 8,000 mAh, depending on the chemistry and brand.

Chemistry Types

• Alkaline: Common for general-purpose use; long shelf life.
• Zinc-carbon: Economical but lower capacity and shorter lifespan.
• Rechargeable (NiMH or NiCd): Can be recharged multiple times; environmentally friendly.

Common Uses

C batteries are typically used in devices that require medium power consumption, such as:

• Flashlights
• Radios
• Toys
• Musical instruments (e.g., portable keyboards)
• Medical equipment

The C battery's size and capacity make it suitable for devices needing sustained power over a longer period than AA or AAA batteries can provide.

A standard C (or "D cell") battery typically provides a voltage of 1.5 volts (V). This is the nominal voltage for alkaline C batteries, which are commonly used in a variety of household and commercial devices, such as flashlights, portable radios, and some types of toys.

For rechargeable C batteries, the voltage can vary depending on the chemistry:

NiMH: Rechargeable C batteries using Nickel-Metal Hydride chemistry usually have a nominal voltage of 1.2 volts.

Li-ion: Rechargeable C batteries with lithium-ion technology typically have a nominal voltage of 3.7 volts, but they are often used in configurations that provide a lower voltage suitable for certain devices, such as 3.6 volts when two cells are connected in series.

C and D batteries differ mainly in size, capacity, and usage. C batteries are smaller (50 mm long, 26 mm diameter) with a capacity of 3,800–8,000 mAh, suited for medium-power devices like flashlights and toys. D batteries are larger (61.5 mm long, 33 mm diameter) with a higher capacity of 12,000–20,000 mAh, ideal for high-power devices like large flashlights and stereos. Both provide 1.5V, but D batteries last longer in high-drain devices due to their greater energy storage.

A C battery has a simple, cylindrical shape and is larger than AA or AAA batteries but smaller than a D battery.

You can sometimes replace D batteries with C batteries using adapters, but they are not directly interchangeable due to differences in size and capacity. While both provide the same voltage (1.5V), C batteries are smaller and hold less energy, so they may not last as long or fit securely in devices designed for D batteries. Adapters can help fit C batteries into D battery slots, but performance may be compromised, especially in high-drain devices that rely on the larger capacity of D batteries.

Rechargeable batteries have been around for a long time as power sources, but they’ve never been as efficient, long-lasting or affordable as they are today. In almost every case, rechargeable batteries are the better option, but there are still plenty of uses for disposable, alkaline batteries. For C batteries, disposables are good for emergency kits and flashlights.

This may be due to several reasons:

1. Over-discharged battery: If the battery has been left unused for a long time, it may need a brief “activation”. Try leaving it in the charger for an additional 20-30 minutes, and it may begin to charge normally.
2. Incorrect installation: Ensure the battery is inserted with the correct positive (+) and negative (-) polarity. Improper placement will trigger an error.
3. Incompatible charger: Some chargers only support lithium batteries or specific chemistries. Make sure you're using a Ni-MH-compatible 9V battery charger.
