The BDC70 is a longer lasting Li Ion rechargeable battery for Topcon and Sokkia surveying instruments. With an output voltage of 7.4V and 5200 mAh capacity, it is an excellent choice as a replacement or spare for the Topcon/Sokkia BDC70  battery.

This rechargeable battery works with TopconES, OS, DS, PS  series total stations, Sokkia CX, FX  SETX, SRX,  SX series total stations, Topcon HiPer II and Hiper V GNSS receivers, Sokkia GRX1 and GRX2 GNSS receivers.



The batteries can be stored at –40 °C to +55 °C (–40 °F to +131 °F). Do not store batteries inside the surveying instrument. After storage, charge the battery fully before use. NiCd NiCd batteries can be stored for an unlimited period in any state of charge. NiMH NiMH batteries must always be stored fully charged and recharged after 180 days at the latest. High temperatures and high atmospheric humidity accelerate self-discharging. We recommend storage in the range from 0 °C to +20 °C (+32 °F to +68 °F) in a dry environment. If NiMH batteries are stored in the discharged state for an extended period irreversible damage can be caused. Li-Ion Li-Ion batteries start to deteriorate from manufacture. To reduce the aging effect, store the battery in a cool place at 10%–50% state-of-charge. Li-Ion batteries do not require regular charging while in storage.


Charging temperature

The charging temperature (ambient temperature) has a significant impact on the life of the batteries. Charging at high temperature can cause loss of capacity. These losses in capacity are irreversible. Even with several charging and discharging cycles, the original capacity can no longer be obtained. For optimal charging, we recommend that the batteries be charged at ambient temperatures as low as possible (+10 °C to +20 °C / +50 °F to +68 °F). The permitted temperature range in which charging can still be performed is between 0 °C and +35 °C (+32 °F and +95 °F). 


Useful capacity

The temperature has a particularly significant effect on the useful capacity of a battery. In accordance with the operating range for the surveying instruments, the batteries can be operated from –20 °C to +55 °C (–4 °F to +131 °F). With reducing temperature the useful capacity drops rapidly. Continuous use in the upper temperature range (> +45 °C / +131 °F) shortens the life of the battery.
