HKJ為優質充電器所下的註解 http://www.candlepowerforums.com ... wfull=1#post4141186
For people that wants 4.20 volt on their batteries, this is not the charger, this charger uses the correct algorithm and the battery voltage will drop slightly below 4.20 volt when the charge is stopped.
During charge it will go up to 4.20 volt, but when charge is finished it will probably drop to 4.19 or 4.18 volt (Depending on age and size of battery).
Me remark above was because some people believes that a fully charged battery has to read 4.20 volt. That is not correct, the charger has to use 4.20 volt and that is not the same.
