Batteries Reviews

I purchased this battery because it is listed as a replacement for a Sony BP-T31 used in a SPP-S9101 cordless telephone which has a spare battery charging compartment.

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.

This is a rip-off, NOT a FUJI NP-80 Battery.
It is an overpriced counterfit knock-off product.
It may fit your device but it is not a FUJI product.
Buy the other vendors products that are clearly marked as a substitute for the FUJI NP-80. The people who admit they are selling substitutes for the FUJI NP-80 sell their batteries for half the price of these vendors who claim their product is original FUJI equipment.

Ergonomics: 2 stars.
Functionality: 1 star.
Company: 1 star.

It's a great idea. Prolong the battery life of your iPod so it's virtually infinite... that sounds great. I thought it was a great device until I had a potentially dangerous problem with it.

First off, the design is quite poor. The device is large and bulky, and the power connector should be integrated into the device so the rubber wire/cord it does not have the potential of getting torn, broken, or stripped in some way. The suction cups-- well, I haven't had any bad experiences yet, but suction-based plastic to affix a 59.99 piece of equipment to a $500 piece of equipment... I don't trust it.

The major problem with my battery pack was that it continually overheats and melts the innerds of the device. The springs are ruined, I can't use it, and Belkin refuses to replace it. Fortunately I haven't gotten seriously burned. But either way... Don't waste your money, especially since it's your safety we're talking about

This battery is supose to work in sony products that use npfm50. It does not work. I thought I would save money with this battery and now I have to send it back and buy a sony battery.

I did not realize that the Canon digital camera that I ordered through Amazon came with its own battery charger. I attempted to contact J&R Music World to get a return authorization, and after many phone attempts, I gave up. No one would answer their customer service phone. I then attempted to get this authorization via their web site (as they recommended), and I sent them all pertinent details with the return authorization request. They ignored my E-mail and never responded. I will never buy another item from them. I am now stuck with an unneeded battery charger and out the $44.78 charged by them.

I own a Canon ES8600 camcorder which is a fantastic deal for the price ($270). What blows me away is how Canon has the nerve to then charge $165.00 for an adaptor to charge your camcorder battery in your car. An item like that costs only a few dollars in parts and labor, but because it's proprietary (menaing you can'y buy generic parts and make one) to Canon's batteries, they feel they can justify the cost. This is dissapointing to say the least. There isn't much to review; the item charges your battery in your car. Done. $165.00?? Can Canon do more to say "we don't care to be in support of our customers"?

LB-51 cannot be used directly with the i70 or i80 printer. It needs the housing that is only available within the CK-51 or LK-51 (of which, the LB-51 is part of those packages)

I figured I'd save money and purchase this battery instead of one of Canon's for my S45 camera. My battery never charged. Just blinks red and green. Manufacturere wasn't any help when I finally reached them. Not worth it at all.

I use to have the old DeWalt DW911 radio where I had to put a coat hanger on to get better reception. I thought that their newer unit would be better reception, boy was I wrong. The antenna is bigger, but I can only move it in 3 -directions, side to side and towards the back. The handle prevents it from going foward. I guess I will have to find a new coat hanger. It came with this plastic CD case holder, but now I have to buy a CD player to go inside.

Who would pay $ for one battery; when you could purchase 2 batteries, a charger and the drill itself for $$???.
Why on earth do manufacturers price disposable items such as this so high?
I for one will purchase a new drill----------but it will not be a DeWalt!
Perhaps the same problem will occur with another brand, but I will feel better at the start giving Bosch or Porter Cable my commerce.
