High Temprature (Temp) battery series is well developed by special engineering and special cathode and anode materials. It ensures good cyclic performance of charge and discharge in high temperature environment. The charge efficiency meets over 70% when it is under 80℃. Ronda’s high temperature battery series is widely used for electric or electronic equipment under high temperature.

Ronda have manily 2 type of temperature range: 55℃ and 70℃, they are mostly applied for emergency lights, guidance lights, robots, medical inststruments, backup storage markets. About 80% of produced high temp battery packs are exported to Europe and North American market. We have custom- made nickle tab leads and connectors for this battery pack. Below are some example:

Low temperature battery Ni-MH series is designed and manufactured by special engineering and special cathode and anode materials. The discharge efficiency is over 50% at the discharge rate of 0.2C when it is under -40℃. Ronda’s low temperature battery series is widely used in -20 ℃ and -40℃for solar lighting, cold-proof equipment, military equipment and aerospace apparatus, minging etc in the cold areas.
