The battery slowly charges a capacitor, which is then discharged through a flashbulb to provide a high-current pulse to ignite the bulb. [2] Higher-voltage photoflash batteries were also made to fire reusable xenon electronic flash tubes, which require a high voltage, without the use of circuitry generating this voltage from low-voltage batteries.
Duracell also manufactures specialty batteries, including NiMH rechargeable batteries and batteries for cameras, watches, hearing aids, etc. Their two main battery brands are "CopperTop (Plus)," marketed as longer-lasting, and "Ultra," directed mainly at users of digital devices and devices that need more power.
A silver oxide battery (IEC code: S) is a primary cell using silver oxide as the cathode material and zinc for the anode. These cells maintain a nearly constant nominal voltage during discharge until fully depleted. [ 2 ]

Nickel–zinc batteries have a charge–discharge curve similar to 1.2 V NiCd or NiMH cells, but with a higher 1.6 V nominal voltage. [5]Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio – as little as 25% of the mass for the same power.
