I have now just exhausted a second battery in my 2005 Astra Bertone Cabriolet with just 49K on the clock. The new battery I connected in April now doesn't even have enough juice to lock the doors. It's been on a couple of runs, but mostly stood parked during this COVID milarky. The previous one was disconnected for six weeks, reconnected when it worked a little reluctantly and then died within a fortnight. The only conclusion is that batteries are draining away somehow. Any ideas? I can't keep replacing them, they're a bit pricier than bloody Duracells.
