( because it doesn't measure how much current the battery can deliver.) I guess a 12V lead-acid battery might read 13.5V immediately after disconnecting from a charger, but half an hour later it's likely to be between 12.8 and 13 if it's in top shape, less if not. But at least if it reads close to 13V you know that it's accepting some amount of charge. I suspect there are a lot of dumb chargers going into the landfills - I just noticed a little 'brick' in a friend's garage amongst a bunch of old unused similar stuff. On the cheap plastic stamp, it reads 'output - 12V, 1.0 A'. He couldn't remember what old electronic device it came with. I believe most of these little transformers/power supplies are unregulated, so that one will probably show 14 or 15V open circuit if he were to plug it in. I'd think it would charge a bike battery in a half dozen hours. |
