C/LR14 - D/LR20
For high power demands. Gas stove igniters, vintage large flashlights, and portable radios often use C or D type (LR14 / LR20) large batteries. VIDEX guarantees long-lasting operation without interruptions.
Why buy large batteries from VIDEX:
- Premium Alkaline power: Powers high-drain devices without a quick "drop-off" effect.
- Ready for winter: Works stably even in cool and damp conditions (ideal for camping lanterns).
- 5-year shelf life: Won't leak and will retain their quality for years until needed.

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.
