Hi guys,
Have popped the lid on my sony R7 reverb as every time I powered it up is says "battery low". It is a sony 3V lithium battery but it seems to be in a small clamp with tiny spot welds. Do you unsolder it or get a new clamp and put the new battery in that? Or rig up some other option? Any help much appreciated.

p.s- going back a few posts, but those times of trying to tweak and tweak reverb plugs until I was happy are over. For the little bit of extra effort feeding it out and recording it back in the aural benefits are superb. (and for not a lot of cash either)

you can buy a battery with solder tags on it, and you then unsolder it and replace from the pcb. I normally get such things from Wes Components or you could find a battery specialist.

Thanks Rob. cheers.

The battery in the R7 is a solder-tag type. You will need to desolder the existing battery and then solder in the replacement. Check the circuit board very carefully to make sure that there has been no chemical leakage from the battery - if there has been, let me know.

[i]Before[/i] doing any of this, you may want to back up any user presets you have created - this can be done by way of a MIDI file dump - the instructions are in the user manual.

Have checked WES, and a mob in perth. But can't find a CR 2025 horizontal mount with 10mm distance on the legs. Can only find 20mm?? Any heads up would be great. thanks

Try Farnell Electronic Components. I imagine that RS Components would also stock a suitable part. You can also obtain sockets for these batteries and then you only need to insert a standard coin cell into the socket.

I can't remember off the top of my head whether you can easily fit one of these sockets into an R7. In most cases you usually have to bend the legs on the socket a little to get it to fit into the original holes. You may not want to do this unless you are fairly confident with your DIY skills. The upside is that it'll make it very easy to replace the battery in future.

The last time I bought one of these I got it from Sony Spare Parts at North Ryde. Try them.

Barney is in Melbourne - North Ryde no good for him. Try Speedy Spares in Melbourne.

Thanks for the tips, I like the idea of a battery holder a lot , keep up the good work.
