Apart from their normal characteristics, BMB Li/SOCl2 batteries might be the outstanding in following aspects:
1. Low Passivation. 
Passivition is the nature of lithium thionyl chloride batteries.  It is also the reason that Li/SOCL2 batteries have very low self discharge and long shelf life.  GMB’s production procedures require tight control of moisture in the assembling line and the parts used in the batteries to minimize the passivition of their Li/SOCL2 batteries.  GMB produces the best quality Li/SOCL2 batteries among all the Chinese manufacturers.

2. High and Long Discharge Curve
Safety is always the first concern when GMB designs their spiral (high power) Li/SOCL2 batteries.  With the safe design, GMB’s spiral Li/SOCL2 batteries also have high capacity.  Especially, with large discharge currents, GMB’s spiral Li/SOCL2 batteries out perform all other brands. 

3.  Quality Materials
GMB ER batteries adapt no common materials; all the materials are chosen according to their demand for 15 year shelf-life, stable performance and safety under hard working conditions
4   Safety Characteristics
A.  Electrolyte has been innovated, allowing over discharge to certain extent;

1. GMB ER batteries have to passed all these safety test before sent out:
   Vacuum Pressure Test
   Vacuum Press Test Chamber
   Imitating the condition in a flying airplane,tes the integrity of batteries with surrounding pressure as low as 0.01Kg/ cm2    . 
   
   Battery Capacity Analyzer
   Analyze battery capacity and automatically records battery capacity test data for both constant resistances and constant discharge currents.
   
   High Temperature Test Chamber
   Test batteries under high temperature up to 160℃ low temperature test chamber
   Test batteries under low temperature as low as -70 ℃
   
   Tension Strength Test Chamber
   Test the tension strength of materials and welded joint, especially for the spot welded joint.
   
   Shock Test Equipment
   Test the integrity of batteries under shock impact with
   
   Vibration Table
   Test the integrity of batteries under vibration with presetting frequency.
