Power problem in CADDX RANGER 7600

Hi all,
I have a CADDX RANGER 7600 alarm at home for more than 10 years without problems, but now the red led "Power" is blinking instead of fixed. According to documentation, it is low battery indication, so I've replaced but still the same. Then I measured the voltage that alarm is providing to the battery and I found that it is providing only 13 volts to the battery (measured without battery connected) instead typical 13.8 volts, and I guess that it can be the cause of the problem. There is a variable resistor named "P1" which could set the output power to battery, but I am not sure. Could anyone help?.
Thank you a lot.

Give it 24-48 hours. The new batteries often aren't fully charged, and the system needs some time to equalize them (it's really a trickle charger). You should not need to adjust the trimmer pots on the power supply.

It was one month ago when I installed the battery. Now the battey voltage is the same than output power 13v, but still the led flashing.

You can try fooling with that trimmer pot, but this may be a sign that this system (which is 20+ years old, at it's newest) is fading for the fence. The law of entropy hasn't been repealed.
