The current output is sufficient for me. I take care of so that a slightly stronger consumer (Kofferraumkit, powerful traction motor for opening the tailgate with remote locks and handles. Universal, 12V.) And the already approved themselves a lot. So I had to charge the battery in the first month of use, because the open circuit voltage was then only just under 11.8V. Since I'm in 4-6h again at full capacity. Am happy with it. But I do think that the battery was fully charged on delivery. The battery, there is also more Ah, but also the more difficult the chunk is then. I find that this battery is a good compromise with 7.2Ah.
