Trickle charge regime for NiCd Cell

[treez]

Hello,

We wish to use the NiCd D cell "D5000" (5000mAh) from Tenergy.com in our emergency light.

D5000 NiCd D cell:
https://www.tenergy.com/Tenergy-NiCd-D-5000mAh-Rechargeable-Button-Top-Battery

The recomended trickle charge in the datasheet of this cell is 0.03C to 0.05C (as in attached datasheet).

In our product, we have available a current source which is anywhere between 0.068C and 0.08C (340mA to 400mA)

What pulse duty cycle must we use with our rough current source in order to trickle charge this cell and still keep to within the battery capacity lifetime gaurantees?

A trickle charge is a continuous charge at a low current to replace the charge that leaks away.
I could not find a detailed datasheet for the Tenergy cell you are wanting to use.
