Can the LTC2941 or LTC2942 be used with a 3-Cell Series NiCD?

Hello.

I'm looking at using the LTC2941 (or 2942) for use as a gas gauge for a 3-Cell In Series NiCD Pack for general gas gauging. The datasheet mentions it's designed for Li-Ion but the operating voltage checks out (even under my charger, a PowerStream PST-3P10-N0508 which is 1.6V/cell and peaks at 5.25V).

I'm still relatively new to the fuel gauge space, but I'd imagine there's no chemistry limitations here since this is a fuel gauge and not a charger IC. So I suppose I'm looking for any underlying asterisk so I don't get burned.

Any advice is appreciated.

Thanks.
