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.ReviewsWith all the positive reviews, I must've just gotten unlucky on a bad batch of the white wrapper version. I'm getting 1800-2100 mAh on all four of my batteries even after 2 full Refresh cycles on my LaCrosse charger. This is obviously well below the stated "minimum 2500 mAh" on the batteries. I love Sanyo normally and I'll continue to buy their Eneloop series, but as of October 5, there's at least a small chance of receiving a bad batch of these batteries.
I recently started using them about a three days ago. I put two of the 4 batteries that came in the package in a wireless mouse; two days later, the batteries were dead. I replaced the other two batteries in the same wireless mouse and they were dead as well. All four batteries had been fully charged prior just moments before placing the two batteries in to the wireless mouse. I don't know, but I think I got a bad batch. All the positive reviews and I end up with 4 that are worthless.
First off, this review is based on my experience and not scientific tests. I purchased 8 of these for use with my Nikon SB-900 and SB-600 flashes. When they are fresh out of the charger (La Crosse BC9009) they will recycle the flash extremely fast and last for about 150 shots. However, if I charge them and leave them in my camera bag for a 3 days I'll get about 50 shots. If I charge them and leave them in my bag for a week, they are stone dead. Overall, the batteries that were included with my La Crosse charger (Lacrosse 2600's) out perform the Sanyo 2700 by about 2 fold (again, not scientific). I've been testing a set of 4 Eneloops for about a month and I really like them. The Eneloops give me more overall shots and hold a charge for considerably longer - there is a small hit on the recycle time, but for me the upsides of the Eneloops outweigh this.
I have used many different rechargeable AA batteries over the years. I have been using this battery for several years. I find myself purchasing more and more for many items around the house including toys for two children (we all know how many batteries these use). This battery has the highest milliamps I can find anywhere on the internet. The number of recharges this battery can take far exceeds the total number of recharges of most common rechargeable AA batteries like the Radio Shack rechargeable batteries. Furthermore the length of time this battery can be used on one charge more than doubles the length of other common AA batteries including rechargeable and disposable.
I do not work for the manufacture, I am just a consumer who strongly advocates the use of this rechargeable battery.
Feel free to contact me if you want further details: [...] I'd be happy to answer any questions or concerns.
I bought these batteries on the basis of the positive reviews I read here, but my experience was not as good as others. In particular, I did not get the consistency of capacity that R. Anderson reported. I used the Lacrosse BC-9009U charger's testing function to measure the capacity and got widely different numbers for the four cells, ranging from under 1000 maH to 2100 maH. I believe those numbers to be accurate, since in actual use the cells differed widely as well.
Perhaps the manufacturing process or quality control has changed since others had good experiences with these cells.
