Introduction:
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.
Storage
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.
