Questions about this item

How much heat does the 12.0V 3000mAh pack generate during continuous daily use?

The Ni-MH chemistry and built-in overcharge, over-discharge, over-voltage and short-circuit protection limit heat rise during all-day operation.

Does the 132.7 x 45.4 x 45.1 mm pack need any extra connector or adapter to fit the RA Combo 4720110?

It matches the original battery specifications exactly, so it slots into the RA Combo without additional parts.

Will the 36.0 Wh replacement work reliably in an older RA Combo unit that has seen heavy cycling?

Yes, the cell-level protection circuitry and ISO9001, RoHS, CE, UN38.3 and MSDS certification ensure stable performance in aged devices.
