What is a LR44 battery?
LR44 (also sold as LR44H) is a 1.5V Zn-MnO₂ button cell rated 118mAh. Alkaline zinc-manganese dioxide cells deliver 1.5 V with a long shelf life, which makes them the everyday choice for low to medium drain devices such as toys, torches, meters and thermometers. TIANQIU manufactures and supplies it factory-direct, with OEM label and packaging.

Documentation
What do buyers ask about the LR44 data sheet and EU declaration?
Where is the EU declaration of conformity for the LR44?
Every LR44 shipment carries its own EU declaration of conformity (document TQ-EUDOC-LR44-20260701) and an MSDS. Ask for the current file set and we send the signed copies.
How is this page different from the LR44 model page?
This page is the technical record: capacity, the performance table with its discharge conditions, materials and the compliance file. The model page covers the LR44 as a product — interchangeable numbers, packaging formats and bulk supply.
Are the LR44 performance figures measured or nominal?
The performance table is the measured data we hold for the model at the discharge conditions printed with it. Nominal figures are labelled nominal, and typical capacity is given as a range because it moves with the cut-off voltage.
Ordering
What do buyers ask before ordering the LR44?
How long does a LR44 battery last?
LR44 is rated 114mAh and runs for 560.0 hours under our published test — test conditions: 6.8KΩ 24h/day to 1.2V @ 20±2℃. Service life in your device depends on the load and the cut-off voltage, so send us the device and we will size the cell for it.
What is inside a LR44 battery?
The LR44 is built from Manganese, Graphite — a Zn-MnO₂ system at 1.5V, rated 114mAh, about 1.9g. The material list belongs to this model's technical file, and the MSDS for the chemistry comes with the documentation set.
How long can a LR44 be stored?
Our storage statement for the LR44 reads: One years under normal storage conditions. Keep the cells in the original packaging; the storage and transport guidance that applies to this 1.5V Zn-MnO₂ model goes out with the shipment paperwork.
Is the LR44 rechargeable?
No — the LR44 is a primary (non-rechargeable) cell. Charging a primary cell can cause leakage or rupture, so replace it rather than recharge it. If your application needs recharging, ask us for the rechargeable range.
Which documents come with a LR44 order?
Each LR44 consignment carries its own EU declaration of conformity (reference TQ-EUDOC-LR44-20260701) and an MSDS. Transport documentation is issued for the consignment as the destination market requires.
How do I order the LR44 in bulk?
Send the model, your annual quantity and the packaging format. First orders start from 50 cartons per product line, and printing on the cell, blister card and box is done in our own plant with your logo and barcode.
How do I get LR44 wholesale pricing?
Factory-direct with OEM custom label & packaging. Samples available.
