I found on the internet a guy who has reverse engineered one of these USB Ni-MH cheap chargers. It's circuit is shown below.
I have 4 questions:
1. How does it work?
2. Will it stop the battery from charging when it is fully charged?
3. What is the charging current for the values shown?
4. I need to charge a 750mAh AAA Ni-MH battery, how many hours should I wait to get charged with these values?
I won't expect any kind of performance and the battery may be mischarged, but will it really work without exploding the battery?
