There is one potential downside. If you look at the illustration below you will see that I have circled (in white) the posts that the Polaroid battery snaps onto when you want to use battery power. In two of the three units I tested, this system worked fine. But on the third, the pins were slightly bent (received that way from the factory) and try as I might, I couldn’t get the battery to slide onto the pin. That particular light could only then be used with AC/DC power. This may simply be a case of a bad copy of the product making its way to me. But you should look closely at the design.
NiCad batteries often die in such a way that they won't take a charge and have zero voltage. It would cost you a lot of money to replace your old Polaroid battery with a new battery from the manufacturer.

I like the convenience of the item. It's nice to carry the charger and batteries without all the extra cords. The time to charge is a pain. I plan to replace them with the AA 1000-1800 Polariod Rechargeable batteries. These are rated to charge in 11-21 hours. This makes them more reasonable to take on a trip.
Whether for portable electronic accessories or for kitchen wall clocks and the like, Polaroid batteries have the long-life necessary to handle your power needs. Polaroid super alkaline batteries come in 5 different sizes to suit your specific purposes, and they're priced by the case, so these Polaroid batteries are a great deal for volume purchases. Use the drop-down menu to select 9V Polaroid batteries (comes 12 per case), "AA" (24 per case), "AAA" (24 per case), "C" (12 per case), or "D" (12 per case).
