Ni-CD High-Temperature Batteries

Brief introduction

In certain electrical apparatus, it is required that the battery equipped to be charged at lower current and under relative high temperature environment(up 50℃).Under such a condition, the normal batteries owing to the limits of their structure and material can't be fully charged, and thus low discharge capacity occurs, it is no help even if the charge time is extended. Yinyoo high temperature batteries have been developed aiming to such special application by adopting material and technology. We ensure that the type of batteries have the features of the high charge efficiency trickle charge condition under high temperature, as well as prolonged cycle life and safety.



1. Compared with the normal battery with the same size, the high temperature batteries not only have full advantages of the high charge efficiency at very low current and high temperature, but also have the approximate electrical characteristics as those of the normal battery.
2. Compared with the Ni-CD high temperature battery, the Ni-MH high temperature battery can reach the same capacity in smaller size. It hence saves space for the electrical apparatus. Also as it is well known that Ni-MH battery is environmental friendly battery, but the price of the Ni-CD high temperature batteries is cheaper than that of the Ni-MH high temperature batteries


The Usage Introduction

1.Trickle charge current:1/30C-1/20C,Applicable ambient temperature:0℃-70℃;
2.Due to the specific design in certain conditions, overcharge at the current above 0.15-CmA is not allowed.
3. The battery performs better when it is discharged at the current of less than 1-CmA,as it is not designed for the application of high current discharge.
4. The battery can meet the high temperature accelerating life test and last more than 4 years under floating charge. During this period, no maintenance is needed for the battery, as considering the battery is mostly for the applications of emergency facilities. We recommend the end user have the battery checked every other year. A compulsory substitution of battery is required when it is in service of 3-4years.


The Applications

Emergency lights; guidance lights; robot; power-protecting equipment; medical instrument; solar battery; backup storage appliance.
