9V Batteries
Smoke detector starting to beep in the middle of the night? That means it's time for reliable energy. The VIDEX 9V battery offers a long and stable lifespan for devices your safety and work depend on.
VIDEX 9V Alkaline strengths:
- Long-term stability: Ideal for smoke and carbon monoxide detectors requiring continuous current for years.
- Professional application: A reliable choice for microphones, multimeters, and measuring instruments.
- Anti-leak casing and a guaranteed 5-year shelf life.
Don't overpay for a loud name - choose excellent quality at a fair price. Find your 9V battery in our e-shop!
Q: Why are 9V Krona batteries classified as a block and what is the difference between 6LR61 (Alkaline) and 6F22 (Zinc-Carbon) electrochemistry?
Q: Why is it mandatory to use 9V VIDEX Alkaline or Lithium batteries in smoke and gas detectors?
Q: Why do the contacts of 9V Krona batteries have different shapes and how to prevent short circuits during storage?
Q: Why is a 6LR61 alkaline block important in electric guitars and wireless microphone transmitters?
Q: Does a rechargeable 9V Krona NiMH battery completely replace a 9V alkaline battery?
A: Inside, the 9V Krona block consists of 6 series-connected 1.5V cells (6 x 1.5V = 9V), hermetically sealed in a rectangular housing. The 6LR61 alkaline block provides a capacity of up to 550 mAh and low self-discharge in smoke detectors, whereas the 6F22 zinc-carbon model rapidly loses voltage under load.
Q: Why is it mandatory to use 9V VIDEX Alkaline or Lithium batteries in smoke and gas detectors?
A: Smoke and vapor detectors continuously scan their optical chambers and require strong audio signal power in the event of an alarm. A 6LR61 Alkaline block guarantees at least 2–3 years of continuous standby operation without a voltage drop, preventing false warning beeps or the device failing to respond during an alarm.
Q: Why do the contacts of 9V Krona batteries have different shapes and how to prevent short circuits during storage?
A: Both contacts of a 9V Krona battery are located on the same plane: the narrower one is positive (+), and the wider socket-type contact is negative (-). If the contacts touch metal objects during storage, an instant short circuit and rapid overheating occur; therefore, the protective plastic cap must be kept on until installation.
Q: Why is a 6LR61 alkaline block important in electric guitars and wireless microphone transmitters?
A: Active guitar pickups and audio transmitters demand a constant direct current voltage without fluctuations. If the voltage drops below 7.5V, the audio signal begins to distort, background noise appears, and sound drops out, whereas the 6LR61 Alkaline block maintains a stable audio path throughout the load cycle.
Q: Does a rechargeable 9V Krona NiMH battery completely replace a 9V alkaline battery?
A: A rechargeable 9V NiMH battery nominally provides 8.4V (consisting of 7x 1.2V cells), which is slightly lower than the 9.6V starting voltage of an alkaline element. In audio equipment and microphones, it provides the economy of regular charging cycles, while in smoke detectors, due to low self-discharge, preference should be given to the single-use Alkaline 6LR61 battery.
