I want to know what are the voltage and A/h of the two little rechargeable battery into the AudioControl SA-3055 RTA/SPL meter. I need to remplace it because they are supposed to hold 4 hour with the rta ON and they just supply it for around 30 to 40 min... and they leak!! (but my rta is OK..)
they are in series and i think they are 4 volt each because i saw that each battery are diveded into two cell (the plastic separation) and normally one cell is 2 volt no ?
Well.. if anyone can get me any info about it i'll appreciate !
thanks !

They probably use Nickel metal Hydride or Nickel Cadmium batteries, so each battery is going to be around 1.2V nominal. If you tell me the approximate size of the individual cells I can give you a rough estimate on the Ah.

The batt are dark grey plastic (like in small UPS)and the dimension are around 1,5 x 1,5 by 4 inch height for each batt (2 total).They are sealled lead battery and the shape is square prism. Usually, the other battery like this have spec writed in red on one side, but the battery in my RTA have nothing. I said that i think that each block are divided in two compartment. Usually a 12volt nominal batt like this have six compartment and logically they should have 2 volt nominal each..

Yes, if the batteries are lead acid they are 2.1V per cell. I'm not sure of the Ah rating on lead acid but I would think maybe 1.5Ah would be close.
