The battery's life in the radio is essentially its shelf life. In more recent times, they were popular in schools and colleges as a convenient variable voltage source in science classes. EverReady was still manufacturing them in the 1970s. The most popular battery is the 9-volt type with taps every 1 + 1 ⁄ 2 volts that accept banana plugs. [1]
1.5: 17 × 50 More common as a NiCd or NiMH cell size than a primary size, popular in older laptop batteries and hobby battery packs. Various fractional sizes are also available; e.g., 2 ⁄ 3 A and 4 ⁄ 5 A. B: U10 336 (Russian Federation) #3 (China) R12 (carbon‑zinc) LR12 (alkaline) 8,350 (alkaline) 1.5: 21.5 × 60
The energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity, although some are equipped to use a vehicle's 12-volt DC power outlet. The voltage of the source must be higher than that of the battery to force current to flow into it, but not too much higher or the battery may be damaged.
A C battery measures 50 mm (1.97 in) length and 26.2 mm (1.03 in) diameter. [3] The voltage and capacity of a C-size battery depends on the battery chemistry and discharge conditions. The nominal voltage is 1.5V. Alkaline C batteries have a storage capacity up to 8000 mAh while rechargeable NiMH C batteries can hold up to 6000 mAh. Zinc-carbon ...
The open-circuit voltage is 1.55 V, the average voltage during discharge is 1.25 V. [9] While the energy density is only around one third as that of a lithium battery, the distinctive virtue of the nickel–hydrogen battery is its long life: the cells handle more than 20,000 charge cycles [4] with 85% energy efficiency and 100% faradaic efficiency.
