Dear Ian
We thank you for your valued enquiry and have pleasure in quoting as follows: NiMH battery AB2761 for the Car Alarm (Audi and Vauxhall Omega Powersounder).
The original battery for this unit was 2 button cells each 3.6 volts 150mAh (Emmerich batteries that are now obsolete). The 2 batteries were set side by side in the alarm unit with a spring connector inside the “figure 8” battery location to connect them in series, and 2 more spring connectors to connect to the circuit board. There is no direct equivalent to the obsolete Emmerich batteries so this battery (Univercell AB2761) is offered as single 7.2v 150mAh battery to do the same job inside the alarm. Some modification will be required to the plastic moulding of the battery location in the alarm. The new battery is 7.2volts so the spring connector inside the “figure 8” battery location is not required. Connection to the circuit board can be by the existing spring connectors on the board or by soldered connection to the tags on the battery. Please observe the battery polarity and install correctly, red is positive. Take care to avoid short circuit when installing the battery.
See pictures attached to email. If the user can suggest any detailed changes to improve the design please contact Univercell. These batteries are made to order.

That's helpful, although my power sounder is a different setup, the two batteries are soldered to the PCB.

A little bit steep perhaps? The two PCB mounted batteries for the newer style sounders are under 4 quid each (2 required) IIRC, and I'm sure they could be bodged to fit just as easily.

The ones quoted in the maintainance guide are discontinued by Maplins?

That was a radio controlled car battery, IIRC? Overkill for a power sounder anyway.

Have a look at BN24B. They are a bit more expensive from Maplin but that's pretty similar to the PCB mounted batteries except the pin arrangement is slightly different.
