Ordering

What do buyers ask before ordering the LR1120?

How long does a LR1120 battery last?
LR1120 is rated 29mAh and runs for 470.0 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 LR1120 battery?
The LR1120 is built from Manganese, Graphite — a Zn-MnO₂ system at 1.5V, rated 29mAh, about 0.78g. 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 LR1120 be stored?
Our storage statement for the LR1120 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 LR1120 rechargeable?
No — the LR1120 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 LR1120 order?
Each LR1120 consignment carries its own EU declaration of conformity (reference TQ-EUDOC-LR1120-20260701) and an MSDS. Transport documentation is issued for the consignment as the destination market requires.
How do I order the LR1120 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 LR1120 wholesale pricing?
