C / LR14 and D / LR20 batteries supply stabilu darbību ar 5 gadu uzglabāšanas laiku industriālā vidē.
Heavy-duty cylindrical cells (LR14 8000mAh / LR20 15200mAh) with Anti-Leak protection and 1.5V voltage are designed for prolonged current supply to industrial equipment. Industrial measuring instruments, portable radio stations, pumps, and high-power luminaires consume a significant amount of current during long-term operation. High-power cylindrical C/LR14 and D/LR20 cells are specially developed for equipment with continuous and high current demand. The LR14 format offers 8000mAh, while the LR20 format reaches up to 15200mAh capacity with a stable 1.5V discharge curve. Equipped with a hermetic housing and a 5-year storage guarantee, these elements provide maximum autonomy in industrial facilities and prevent unplanned equipment stoppage under intensive use conditions.
Engineering parameters:
- High capacity: 8000mAh (C) and 15200mAh (D) for systems.
- Anti-Leak hermeticity: Protects measuring equipment from electrolyte.
- Energy efficiency: Reduces the frequency of equipment maintenance.
The use of industrial batteries guarantees high energy efficiency and drastically reduces the frequency of regular equipment maintenance. To ensure complete energy autonomy also for mobile communication devices during industrial trips, take a look at our Power Banks and Solar Panels solutions.
Q: What is the technical difference between C (LR14) and D (LR20) batteries and in which devices are they used?
Q: Why do gas water heaters and automatic gas boilers specifically require VIDEX Alkaline LR14/LR20 batteries?
Q: How long do alkaline D (LR20) batteries operate in a powerful LED spotlight compared to zinc-carbon elements?
Q: Is it permissible to use adapter shells (C to D or AA to C) as a full replacement for large batteries?
Q: Why is a reinforced steel housing important for large D and C batteries under heavy load conditions?
A: The difference lies in physical dimensions and capacity: the C (LR14) size is 26.2 x 50.0 mm (around 8000 mAh), while the D (LR20) measures 34.2 x 61.5 mm, reaching up to 18000 mAh capacity. The C format is intended for medium-power portable radios and mechanisms, while D elements are used in powerful industrial flashlights and gas boiler ignition blocks.
Q: Why do gas water heaters and automatic gas boilers specifically require VIDEX Alkaline LR14/LR20 batteries?
A: Gas burner spark plugs and automatic valves consume a large current impulse at the moment of ignition. Alkaline LR14/LR20 elements provide low internal resistance and a strong spark for thousands of ignition cycles throughout the heating season, preventing gas boiler startup errors (Err).
Q: How long do alkaline D (LR20) batteries operate in a powerful LED spotlight compared to zinc-carbon elements?
A: With an 18000 mAh capacity, two D (LR20) alkaline batteries provide continuous LED spotlight operation for up to 40–60 hours. Regular zinc-carbon D batteries discharge in just 8–10 hours in this mode, so Alkaline provides 5 times longer autonomy for operational services and construction sites.
Q: Is it permissible to use adapter shells (C to D or AA to C) as a full replacement for large batteries?
A: An adapter shell allows physically inserting a smaller battery into a larger socket, but the capacity remains at the level of the small battery (around 2800 mAh, not 18000 mAh). The device will work, but its operating time will be 6 times shorter, therefore original D (LR20) Alkaline batteries are necessary for prolonged autonomy.
Q: Why is a reinforced steel housing important for large D and C batteries under heavy load conditions?
A: Large batteries contain a high volume of chemical reagents, so in the event of housing damage, the consequences of a leak would be catastrophic for the device's mechanism. An impact-resistant steel casing with a safety valve prevents internal pressure deformations even under the influence of heavy impact or temperature fluctuations.
