Good for NiMH batteries, but look for Lithium Ion batt's for best performance today
Nice small form factor charger set with four AAAA batteries included. This is a NiMH model. Better than NiCd but not as good as the newer Lithium Ion technology. NiMH imseems to be the most common battery tech currently due to its product maturity and value over the oldest NiCd tech, which only stays rechargeable for a year or two if you're lucky. The total voltage is slightly less per battery than "normal" non-rechargeable Alkaline batteries so they will not last long in power hungry devices. If your standard Alkaline batteries lasted a year in the device, expect NiMH to last maybe 30-90 days before recharge.

Seems Good.
These batteries seem ok. So far so good. I have not attempted charging one from a discharged state yet. I think they are delivered in a charged state. Initial charge time in charger was only a few minutes. I then used the battery in my tablet pen and it seems to work ok. Note that as these are NiMh batteries, even when fully charged, the voltage will be lower than disposable batteries. Consequently they may not be suitable for all applications. I saw one review that stated that the charger as a simple diode and resistor. I doubt that is the case as when viewing the charging current it seems to burst to about 330ma then turns off and repeats cycle. Some detailed instructions explaining how the charger is to be used would be helpful. ie does it stop charging when battery is fully charged etc.

Las pilas AAAA recargables para plumas Lenovo
Funcionaron a la primera, espero no tengan fugas y duren. Se pueden cargar con cualquier otro cargador ajustable de 1.2 NiMH o NiCD así que usé el mio de siempre. No he probado aún el cargador incluido. La pluma de la tableta Lenovo funcionó a la primera y sin problemas.
