Amazon.com Product Description Do away with disposable batteries and keep your portable electronics running for years with this four pack of GE/Sanyo AA rechargeable NiMH batteries. Built for long-lasting use, the 2,700 mAh batteries last up to four times longer than standard alkaline batteries, making them ideal for digital cameras, audio devices, and other high- drain electronics. More significantly, when they run out of power, you don't have to throw them away and clutter up the landfill. Simply put them in a charger and recharge them either fully or partially, depending on your needs. All told, these batteries can be recharged up to 1,000 times without experiencing a memory effect. Reviews product not as expected, have another brand of 2000 maH bateries which hold a better charge in canon camera than these do. Thought that be purchasing the 2,700mAh batteries that they would last longer. I was wrong,at least with this brand. look into another brand if you want LONG lasting batteries. Review of Sanyo 2700 mAh High capacity rechargeable batteries I recently Purchased 2 sets of these for an Olympus SP-550UZ 7.1MP Digital Camera with Dual Image Stabilized 18x Optical Zoom camera. This camera eats up batteries. You can put a brand new set of alkaline energizers in the camera and it will power up just long enough to let you know that it thinks the batteries are dead. I have been using the Sanyo Eneloop 2000 mAh Low self-discharge (LSD) for several months. They work but not well. I have to take them right out of the charger and put them into the camera to get 250 shots. If the Eneloops have been charged and have been sitting for 24 hours the camera says they are low on charge and I might get 30 shots. The Sanyo 2700s are better by a mile. For the first time ever I powered up the camera the next day, after using it the prior day, and the camera did not complain that the batteries were about to die. I highly recommend these batteries for applications where lots of power is needed. I also highly recommend using a La Crosse Technology BC-900 on it's default setting which trickle charges the batteries at 200 mAh. To fully charge a set of batteries takes around 13.5 hours, but because the Olympus SP-550UZ can't use the battery's full charge, toping the batteries of only takes about 5 hours or less. May 14 2009 update. These batteries need to be run down and recharged to get the full use of them. The first time I charged these up I only got 84 shots. After using the La Crosse Technology BC-900's discharge and recharge option several times I got 212 shots out of a set the other day. On this shoot I was using the zoom a lot and that uses a lot of power. I shoot RAW so on a 2GB type H card I get about 196 shots. So getting 212 shots out of a set of these batteries is great. I also have tested running batteries dead. When a battery is run down all the way and left for a while it tends to develop micro shorts in it. To a charger it will look dead and the charger won't charge it. Well I found that if I just left the dead battery in the La Crosse Technology BC-900 charger long enough, sometimes over night, It would start charging eventually. The charger charges at 200 mAh by default and runs a trickle charge of 20 mAh to keep a battery toped off. I suspect that even though the charger does not recognize the presence of a dead battery it is still running a small charge through it. This charge is enough to fix the micro shorts over time and then the battery will start charging normally. I purchased 3 sets of 4 of these Sanyo NI-MH. They have charged up nicely to a little over stated capacity. I have not had any problems with them thus far, and don't expect any. I also recommend the La Crosse Technology BC700 Alpha Power Battery Charger. It is the best charger, with great features, that I have ever used. Looks like Delkin has the edge with 2900mAh batteries. Additionally, they have low discharge AAs that are 2300mAh, 200 more than the other brands. [..] from the few times I have used these batteries, they work no better than cheaper brands.
