Removing the Power Meter RAM Battery (BT1)
1 Remove the A2 processor assembly as described on page 109.
2 Remove the A2J1 link to disconnect the battery from the rest of the circuitry.
3 Verify the battery protection circuitry by:
– Ensuring that there are no electrical short circuits across the battery
terminals.
– Ensuring that there are no voltages present which could apply a charging
voltage.
4 Once the protection circuit has been verified remove the battery. The battery is
siliconed to the assembly. It may be necessary to remove it using a scalpel.
5 Store the battery individually in an anti-static (dissipative) bag or suitable
non-conductive packaging.
6 After replacing the battery secure it using a tie wrap. This should be secured
from the top of the A2 processor assembly. The recommended tie wrap part
number is 1400-1154.
7 Replace the A2J1 link.
This power meter uses a lithium battery which may explode if mishandled.
The battery should not be subjected to short circuit of the battery terminals
or to excessive heat.
Do not recharge this battery or dispose of it by burning. Check local country
regulatory requirements on the disposal of lithium batteries.
