Q: What kind of rechargable batteries does the Net3 RFR use?
A: The Net3 RFR uses 2 AA NiMH batteries (Nickel-Metal-Hydride). While the device can use non-rechargable AA batteries (alkaline), do NOT plug a device using alkaline batteries in via USB -- the batteries may rupture or explode.
Q: How do I change the batteries on my RFR?
A: There are four screws, two on each side of the unit. Remove them, and the front cover will slide off, revealing the batteries.
Q: Is there an ETC part number for the batteries?
A: Yes. The part number is BT139 (it is a single battery).
Q: Can I use Lithium Ion batteries instead?
A: No. The charging circuit is not designed for Li-Ion batteries and may damage the batteries, the unit, and the user.
