|I went looking for a replacement battery for a Uniden DGA940 cordless phone handset.|
Quotes ranged from $30 to $35 (Australian). That seemed more than a little excessive for something the size of three AA cells.|
I asked the retailers why the price is so high. One answer attributed it to the fact that the DGA940 is digital. Another said that you've got to allow for the value of the case (of the battery pack).
So I opened the case and found - three AA NiCad cells:|
The flimsy case is stuck to the cells with double-sided tape, lending the pack some rigidity.
A multimeter confirms that one cell is dead. The other two are still operating at full capacity.
|Apart from the print on the wrapping, I discerned no difference between the the AA cells in the battery pack and a bog-standard Sanyo CADNICA N-600AA:|
From a consumer's point of view, Uniden's decision to employ this type of battery pack (when ordinary AA NiCad cells would do the job nicely) inflates the price by over 100% and reduces the value by two thirds: the whole pack must be discarded when only one of three components has failed.
The kicker is inside the battery compartment of the handset:|
Not my area of expertise, but:
So the life of the product is effectively limited by how long the battery packs continue in manufacture (and remain affordable).
|The packaging reveals the brand that, I guess, Uniden reckons will cause their handset to burst into flames:|
|On the new battery pack, beneath a cheap sticker:|
|Is another label:|
