Instructions for battery patch improvement (all numbers in hex).

1) Find four bytes '0D 00 1A 00' twice - origin of full battery
   and empty battery pictures. Replace bytes with following sequences:
     1. For first picture (full battery):
        0D, 0A, 1A, 00,
        0F, 87, 11, C7,
        6F, F7, C7, DF,
        EF, FF, C7, DF,
        EF, FF, C7, DF,
        EF, FF, C7, DF,
        EF, FF, C7, DF,
        EF, FF, C7, DF,
        EF, FF, C7, DF,
        EF, FF, C7, DF,
        EF, FF, C7, DF,
        EF, FF, C7, DF,
        EF, FF, C7, DF,
        6F, B7, 3F, E7
     2. For second picture (empty battery):
        0D, 0A, 1A, 00,
        0F, 87, 11, C7,
        7F, F7, 81, 5F,
        81, 2F, 80, 5F,
        81, 2F, 81, 5F,
        80, 2F, 81, 5F,
        81, 2F, 80, 5F,
        81, 2F, 81, 5F,
        80, 2F, 81, 5F,
        81, 2F, 80, 5F,
        81, 2F, 81, 5F,
        80, 2F, 81, 5F,
        81, 2F, 80, 5F,
        41, 37, 3F, E7
        
2) Find from last position byte '14' and replace by '17'
