RTI 40-210742-20 Replacement Battery for ISR-2, ISR-4, T2x, T3x, T4x, and T2i

This is the new replacement battery for the T2x, T3x, T4x, and now also the T2i remotes. This will also be the replacement battery for the new ISR-4 and ISR-2 remotes.

This new replacement battery is purple and has a new style label. It does not have the RTI model number 40-210742-20 printed on the back, but don't worry, this purple battery works with all T2i, T2x, T3x, T4x, ISR-2, and ISR-4 remotes.
