LONGWAY electrical scales battery series are specially designed and developed for weighing instruments. It is developed according to the characteristics of small current, long-time use, low charge state storage, frequent over-discharge, and low charging voltage when the weighing scale in actual use. We adopt advanced R&D technology to ensure that the battery has high reliability, safety without leakage, strong over-discharge resistance, good recovery ability and long service life. The products have obtained UL, CE, RoHS certification, and can be shipped by sea or air.

 

General Features

Reliable without leakage

It can be charged continuously for 48 hours without leakage, and can be used in any direction such as side, horizontal, and upside down.

Super-long service life

Adopt optimization design under deep discharge,and the residual capacity shall not be less than 50% of rated capacity after 96 times of 100hr full capacity cycle life.

Low self-discharge rate & strong storage capacity

It still can be used normally after fully battery storage 2 years, and without affecting its service life

It still can be used normally after continuous storage for 120 days at 50% SOC,and without affecting its service life.

Strong resistance to overdischarge and good recovery ability

Unique lead paste formula and plate ratio design. After the battery is discharged to 0V, the wires are directly short circuited for 3 days. After recharging, the cycle test is conducted 3 times, and the discharge capacity recovers to over 95% after 100 hours.

Environmental friendly product

Meet the RoHS and REACH standards of the EU Battery Directive.
