Strato Pi Base Server; Replacing The Rtc Backup Battery - Sferalabs SPMB21X User Manual

Strato Pi Base server

The Strato Pi Base server comes pre-assembled with a Raspberry Pi 3 Model B or B+
board, in a plastic standard DIN-rail case.
There is no need to open the case, unless a change in the RS-485 termination resistors is
required (see below).
The Micro SD card (not provided) can be inserted through a small opening on the side of
the case. Use a small pen or paper clip to gently push the card in its slot.

Replacing the RTC backup battery

Strato Pi Base has a hardware real time clock with a dedicated long-life non-rechargeable
back-up battery.
Strato Pi Base is shipped with a CR1025 Lithium / Manganese Dioxide (Li/MnO2) battery
installed.
The battery is only used to power the RTC chip when the main power is not available
(when the Raspberry Pi is off). Depending on operating conditions it should last up to two
years if the Strato Pi board is not powered, more if the Strato Pi Base receives external
power.
WARNING
Improper handling of lithium batteries can result in an explosion of the batteries and/or
release of harmful substances.
Worn-out or defective batteries can compromise the function of this product.
KEEP OUT OF REACH OF CHILDREN. Swallowing may lead to serious injury or death in
as little as 2 hours due to chemical burns and potential perforation of the esophagus.
Immediately see doctor.
Replace the RTC lithium battery before it is completely discharged. Replace the battery
every 5 years even if the battery is still working properly. The lithium battery must be
replaced only with an identical CR1025 Lithium / Manganese Dioxide (Li/MnO2) battery.
Do not throw lithium batteries into fire, do not solder on the cell body, do not recharge, do
not open, do not short-circuit, do not reverse polarity, do not heat above 100°C and protect
from direct sunlight, moisture and condensation.
Dispose of used batteries according to local regulations and the battery manufacturer's
instructions.
The RTC backup battery holder is soldered to the bottom layer of the circuit board,
between the GPIO connectors. In the Strato Pi Base server, the battery is not accessible
from the outside. You should first remove the case top body to gain access to the Strato Pi
Base circuit board.
