AG13 / LR44

Device ran out of power and you specifically need an AG13 / LR44 battery? This small Alkaline button cell is perfectly suited for children's toys and digital calipers, ensuring reliable daily operation.


Advantages of VIDEX flat batteries:

  • Pazīstama arī kā (analogi): LR44, A76, 357, V13GA, RW82.
  • Stable 1.5V voltage output throughout its lifespan.
  • "Anti-leak" protection guarantees that acid won't leak and damage your delicate equipment.
  • Secure blister packaging to prevent accidental swallowing (crucial for homes with kids).

Don't overpay for watchmaker services - replace it yourself. Order at opentools.lv today!



Q: What are the standard IEC dimensions and typical capacity of an AG13 / LR44 battery?

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.
