Big Billy Trip 16 - Munstertal to nr. Stollhoffen, Baden, via Titisee

Distance - 176km (3385km total)
I'm having a problem with Germany. I find the language too funny. I can't stop seeing words and pronouncing them to myself in a cod-German voice, slightly high pitched and urgent, and making myself giggle. Maybe it's too much Allo Allo as a kid. Add to that unfortunate sexual double entendre (such as the place I visited today, called Titisee) and I find I'm just walking around laughing at my host country. Not good.
My other observation so far is that the 'working leisure' hair cut is alive and well in Germany, as is the rat tail. Rock on.
(Oh, and the word for exit is Ausfart. Tee hee. Ahem)


OK geeky campervanny bit now, turn off if you're not interested. I'm having real problems with my leisure battery. I bought it anew before the trip, because the last one had karked it (or had it, I now wonder?). It is 75aH, so plenty big enough for an evening of DVD watching or accessory charging, I thought. I have a 300W power invertor, so I can plug in mains powered devices – I have a DVD player, a 14” screen, and a socket for charging this laptop and other things. The invertor has a cut-off alarm, to stop you flattening your battery, and it starts beeping when the battery reads 10.5V. At the moment, it is doing this after about 90 minutes usage, which is a bit shit. By my calculations, I'd have had to be drawing 50A for the battery to be flat in this time (which obviously I haven't been; there's a 25A fuse!). So I'm a bit confused.
My dad has suggested there's perhaps a voltage drop-off between the battery and the Invertor, causing it to read 10.5V before that's actually the case. I will do some investigating along these lines when I get home, but my voltmeter at the fusebox also reads 10.5V, and anyway I wouldn't expect to be losing so many volts from long wiring and poor connections. Even with the TV (5A) and DVD (2A) on, and the laptop charging (2A), I would expect the battery to last at least 8 hours. Maybe my idea of alive and the invertor's (10.5V = dead) are different?
The other thing that's weird is that after the invertor has beeped at me, I turn it off, and the voltmeter starts to slowly creep back up. Before long, it's at 12.5V again, but as soon as I turn the invertor back on it slowly falls back down to 10.5V over about three minutes. Is this normal?
One thing I think I will definitely invest it for 'next time' is a mains voltage hookup kit. Not to charge the battery necessarily, but just so I can run a cable into the van to run mains-powered devices. I could even have it plug into the cupboard that contains the invertor, and have a bypass switch so my devices get their power from the outside source instead.
