Backup battery specifications

Hello,
I have a GRT battery backup system.
I have to replace the battery but don't have access to my plane right now and did not find any informations on the website as the item seems no longer available.
I would like to get some specifications to order a replacement battery.
I think it is a 2.2 amp/h, 12 V lead-acid sealed battery; but I lack the dimensions.

I found this one in France, would it be suitable?

Thanks

Our battery is a PS-1220. That battery looks the same (except for maybe the plastic shields on the connectors) and mentions the PS-1220 but the dimensions don't exactly match. It appears to be a few millimeters taller. I don't think that will be a problem but I don't know how much extra space the box has. The PS-1220 is currently listed as 178mm (L) x 35mm (W) x 60mm (H). I don't have any old documents to compare that with the original part though.
