Old battery read 2.9V and wouldn't hold a charge, so I swapped this in for my 202C and it fired right up on the first try. The 500mAh capacity gives me a solid few hours of use before I need to top it off. Fit was exact, no fiddling with the connector.
Slapped this into my 280C transmitter after watching the install video and it fired right up, no fiddling with contacts. The 500mAh capacity seems to hold a charge longer than the old one that came with the unit.
Battery fits my 280C transmitter snugly and the 500mAh capacity seems right for the spec, but the included wire length felt a bit short for my setup during the swap. It's working fine so far after a couple of charges, just nothing impressive about the build quality.
