A fellow-townsman took a good thing yesterday, dynamoelectric spanner, repair to old boy look. This plays meaning old boy trashy pass. That with respect to problem of look look what. Fellow-townsman says this have more than is needed, also cannot develop report. Batteries is inserted on charger, have a permission to go ahead with some project. Be charger problem or batteries problem after all? Tear open next charger to measure, have voltage output. Why to measure directly charge contact? Because some charger designs are a few more complex, do not output voltage without batteries. Ravel so charger measures electronic transformer directly sub commutate is outputted more intuitionistic. Result charger is no problem. Such word measures batteries, output terminal does not have voltage completely. Have two kinds of possibility at that time, put protection too, bring about batteries to was not outputted, or electric core damaged, without output. Output of voltage of this batteries group is quite high, output carries normal condition should be 20V, the discovery after ravelling is 10 electric core of 18650, two paralell connection become a group, again 5 groups of series connection. Measure electric core with avometer two end do not have voltage completely also, can explaining only so is electric core discarded as useless thoroughly. Two groups of batteries were finished. Uncle said to put 3 years two trashy over- . Batteries is afraid of what deposit for long basically, deposit time too long bring about invalidation easily. Uncle said, buy the fund of two batteries, can buy a new spanner quickly. Do not have method, old boy also was forced to abandon.
