Batteries Reviews

But I digress. Being someone who owns and regularly plays/uses a couple dozen hand-held/portable electronic games (see what I'm talkin' about at http://www.amazon.com/exec/obidos/tg/listmania/list-browse/-/3U1GDAL5MCFA4/ref=cm_aya_av.lm_more/102-0973344-6392964), a trio of remote controls, a pair of mini-flashlights and a graphing calculator, it's pretty much a given that I go through AA batteries like a fiend. However, I do not wish to spend money on new AAs like a fiend. So when my supply is running low I'll usually buy a bulk pack (24+ cells) that gives me the best value for my scratch. Almost invariably, the brand that occupies the best-value end of the battery-purchasing spectrum is Ray-O-Vac. From what I've experienced, they work just as well and last just as long as their Energizer and Duracell counterparts. Which means I can play my fave hand-helds for a good while, and have a few shekels left over to buy a new AA-powered doohickey to add to my already-overflowing collection...

Final aside: Who the hey came up with the bright idea to saddle this product with the three-part fun/educational/durability rating that Amazon/Toys-R-Us reserves for toys and games?! Anybody out there have a clue on how I should rate this product on the 'fun' and 'educational' scales? Um... hello? A little help here...?

'Late

The Sony BP-T31 is a 3.6V, 600mAh, Nicad battery
The AGAIN & AGAIN STB-931 is a 3.6V, 700mAh, Nicad battery

When I received the battery, it was dead: it tested at 0.0V - a bad sign.

I put it on charge in the spare battery charger compartment for 3 days - it came up to 2.5V. It wouldn't power the phone.

I swapped it with the Sony battery in the phone & charged it for 5 days in the phone while charging the Sony battery in the spare battery charger. The Sony battery read 4.05V (it's 2 years old). The STB-931 read 2.547V - it still wouldn't work.

The Sony battery continues to work fine but the STB-931 never would work.

The Sony battery is no longer available; this is the only replacement I've found. I needed this one because my spare Sony battery died.

I rotate batteries at every discharge. It's not what the Nicad battery manufacturers recommend but it's what THEY do.

The STB-931 DOES make a nice paperweight.
