What is a LR41 battery?

LR41 (also sold as LR41H) is a 1.5V Zn-MnO₂ button cell rated 34mAh. 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.

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. The LR41 is produced on our own lines in China and can be supplied as a bare cell, on a blister card or in a printed box. Each is marked for LR41 and ships with its own EU declaration of conformity.

Documentation

What do buyers ask about the LR41 data sheet and EU declaration?

Where is the EU declaration of conformity for the LR41?
Every LR41 shipment carries its own EU declaration of conformity (document TQ-EUDOC-LR41-20260701) and an MSDS. Ask for the current file set and we send the signed copies.
How is this page different from the LR41 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 LR41 as a product — interchangeable numbers, packaging formats and bulk supply.
Are the LR41 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 LR41?

How long does a LR41 battery last?
LR41 is rated 34mAh and runs for 530.0 hours under our published test — test conditions: 22KΩ 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 LR41 battery?
The LR41 is built from Manganese, Graphite — a Zn-MnO₂ system at 1.5V, rated 34mAh, about 0.6g. 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 LR41 be stored?
Our storage statement for the LR41 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 LR41 rechargeable?
No — the LR41 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 LR41 order?
Each LR41 consignment carries its own EU declaration of conformity (reference TQ-EUDOC-LR41-20260701) and an MSDS. Transport documentation is issued for the consignment as the destination market requires.
How do I order the LR41 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 LR41 wholesale pricing?

Factory-direct with OEM custom label & packaging. Samples available.
