SINCGARS HUB and ANCD batteries look similar and can be physically

interchanged. The HUB battery is 6.5 Volts while ANCD batteries are 3

Volts each. If HUB batteries (3 of them) are mistakenly placed in the

ANCD, it will be destroyed. Placing one ANCD battery in the RT HUB

position will cause the RT to lose its fill of data.

Therefore, be sure you know which battery goes where. Always read

the label before installing either HUB or ANCD batteries!
