Since May 3, I test this basic charger and AA and AAA batteries with a consumer site. I am fan of rechargeable batteries in recent years but before the price of major brands I had opted for a private label charger as for batteries. 1 loading Duracell batteries fairly simple although I found the location of small batteries were sketchy, the batteries are not very well maintained and have a tendency to skew. Although it is nice to be able to charge two battery types together is not new to a charger so no bonus for this. Where I am satisfied is that the batteries are equipped with the system duralock which keeps the load 6 months when not used In terms of the first normal load use 4:20 for AA or AAA batteries for 6:00. For now these are my wireless mouse since May 4 and the automatic sanitary fragrance diffuser and everything works perfectly yet I use a lot my PC so I think they are much more effective.
