ARRIS TM822R MODEM BATTERY INSTALL

When installing a battery in my own purchased phone-internet modem - I note the following in an enclosded slip

Please check the following in place before installing or using your Battery
1) You must have an active phone service "provided only by your service provider" on your Phone Modem to use the battery pack.
2) Back Batteries only support the PHONE PART of the modem.
3) Internet part of your modem is not designed to be used with battery pack regardless   
   of if you have a phone service or not.
4) Make sure your modem is directly Plugged into the Wall. (NO SURGE PROTECTORS OR POWER STRIPS CONNECTED OR APC SYSTEMS).
5) Make sure the battery port is in good shape before you insert the battery as in most  cases used and or rental modems have bent pins and may create an issue when inserting the battery properly.
6) Your battery will now require 12-17 Hours Charge initially.
7) A new battery will undergo three battery test stages;
(a) an initial full charge,
(b) a full discharge after that
(c) a full re-charge back to a fully charged state.
8) The full process will take about 6 days.

 MY NOTE   USE 192.168.100.1 TO READ DETAILS OF YOUR MODEM

Question - WHY require plugged in to direct plug and no surge protectors?  I undeersttand the reason for NOT using a supressor on the coax- but why the caution on the 110V ac plug ??

Surge protectors / power strips can go bad, go offline and your battery would drain to zero leaving you without phone service.  Personally, I only use UPC systems and forego the use of internal batteries in my electronics.
