Alkaline button batteries AG13 or LR44 (1.5V, 158mAh) with an 11.6 mm diameter are the world's most requested miniature power source, guaranteeing safe and stable operation for measuring tools and household electronics.
Using a modern electrochemical matrix, VIDEX engineers have achieved an impressive 158mAh capacity in a housing just 5.4 mm thick. This element can sustain a slow discharge for a long time in calipers, electronic thermometers, and laser pointers. The battery's steel housing is equipped with an industrial "Anti-Leak" capsule, which absolutely blocks electrolyte leakage — the most common cause of damage to expensive equipment. They can be safely used in sub-zero temperatures or high heat. Observe polarity and remember that these primary 1.5V elements are not designed for charging and should be disposed of in accordance with environmental norms after discharge, as they are free of mercury and cadmium.
AG13 / LR44 Engineering Data:
- Impressive 158mAh Capacity: Compared to other AG series sizes, LR44 offers the longest downtime and active usage time.
- Physical Parameters (11.6 x 5.4 mm): Precise milling ensures firm fixation in microswitches and secure contact against vibrations.
- Oxidation Resistance: The galvanized housing preserves aesthetics and current conductivity even in damp or dusty work environments.

Q: What are the standard IEC dimensions and typical capacity of an AG13 / LR44 battery?
Q: Why is it essential to use precisely high-quality LR44 batteries in digital calipers and micrometers?
Q: How are LR44 batteries connected in children's sound toys and why must they be replaced simultaneously?
Q: In which specific lighting fixtures are AG13 / LR44 elements most frequently used?
Q: How to ensure AG13 battery contact protection when inserting them into a device compartment?
A: The physical dimensions of the AG13 battery are exactly 11.6 mm in diameter and 5.4 mm in thickness, making it one of the most massive coin cell elements. This geometry allows fusing about 150 mAh of energy capacity into the housing at a 1.5V voltage, which is necessary for devices with medium and heavy micro-loads.
Q: Why is it essential to use precisely high-quality LR44 batteries in digital calipers and micrometers?
A: The measuring instrument's optical sensor operates in continuous standby mode even when turned off. Low-quality elements experience a rapid voltage drop, causing LCD screen flickering and erroneous calibration readings. VIDEX LR44 batteries provide a stable current supply (Low Self-Discharge), guaranteeing accurate measuring tool operation in high humidity and dust conditions.
Q: How are LR44 batteries connected in children's sound toys and why must they be replaced simultaneously?
A: Speaker piezo elements and electric motors in toys require a 4.5V voltage, so three LR44 batteries are connected in series (3 x 1.5V). If only one element is replaced, the difference in internal resistance causes the old battery to overheat or leak, therefore all three elements must be replaced synchronously as a single block to equalize the load.
Q: In which specific lighting fixtures are AG13 / LR44 elements most frequently used?
A: This battery format dominates in mini laser pointers and portable LED light strings (such as bottle cork strings). A laser diode requires a strong initial impulse (over 4.0V, using 3 elements), which the AG13 alkaline system can maintain sufficiently long before a voltage drop that reduces beam intensity.
Q: How to ensure AG13 battery contact protection when inserting them into a device compartment?
A: The LR44 battery housing (flat surface and edges) is the positive (+) pole, while the bottom small bump is the negative (-). When inserting multiple batteries into a metal tube (e.g., a laser), indicated polarity must be followed and side contact avoided, which is why in high-class devices the battery compartment is isolated with a plastic insert.
