Which one is right and which one would you buy? I've read that you should take out the battery because otherwise it always charges and breaks down faster. However, this should not be the case with the newer batteries. But I have an old laptop. From 2011. Will the batteries be revised so that you can leave the battery in or do they stay at the old level and I always have to take it out so that it lasts longer?
The "new" BATTERIES can be continuously charged. So don't take it out.
