Id say with your 5 yr ageing thats a little high. 7A/h are for lower than that IMO.

Plus bear in mind the A/h rating is calculated at a 24 hour discharge time, not 12 so it wont give that amount of capacity at 12 hours anyway. I know its accepted that we still use that rating as if it was a 12 hour discharge.

I did say rough idea.

This is also what Cooper recommend. Probably doesn't include ageing or an activation.

Would normally work it out including an activiton of 15 minutes, myself.

am i right in saying the following

65En control panel 200mA

Extension speaker 100mA

Deltabell Plusn60mA

Pironix MEQ blue x 19 @11mA 209mA

Keypad 90mA

Msnode x 3 @60mA 180mA

Total 839mA

i am going to use the on board communitcator to connect to the ARC

dose this mean that i will require an additional power supply to provide an additional battery as a 7AH battery wont be enough

if im correct and please correct me if i am wrong would i require a 7AH battery in the alarm panel and a 3AH battery in the additional power supply
