Finally, NiMH Batteries that Hold Their Charge - Sanyo's Eneloop Rechargables


I use AA batteries for a few of my digicams and for all of my electronic flashes. When I have a big event, I can go through 6 sets (of 4 batteries) in a shoot. One of my frustrations is that, if I haven't used a set of NiMHs for a few weeks, the batteries can be partially drained when I put them in the device, giving me only half the shooting time compared to a freshly-charged set.

According to Mike Pasini over at Imaging-Resource, Sanyo's new Eneloop AA NiMH batteries have "a new super lattice alloy which increases the electrical capacity of the battery, reduces the internal resistance and allows higher discharge currents -- all good stuff in a digicam."

Mike and company get into some good battery specs in the article, and it's worth taking a closer look to learn what an improvement these new cells are. And the best news? You can buy a kit of 4 batteries and a charger for about $20. If you already have a NiMH charger, you can buy the batteries alone for for just $9 a set. What a great stocking stuffer for your favorite photographer (even if that's you).

Costco recently had a set of these with 8 AA and 4 AAA batteries, plus a charger for just about $20. This is quite a deal and these batteries are great.

Ah thanks for the news .... I hope it will hit the shelfs soon, cuz im frustrated with my batteries!

After unsuccessfully looking around for these batteries in Switzerland and Austria, I discovered that there are a number of other companies that build similar types of batteries. They are easily recognised being labelled as 'Ready to use' or similar. The two types I have bought so far are "Varta Ready 2 use" and "Panasonic Infinium". They both claim more than 80% capacity after one year.

Wow great site! Some really helpful information there.
I’m sorry for little off-topic, but I want to ask you about design of this site.
Did you make this template yourself or got from any templates website?
Looks pretty cool for me. Wonderful well this reading.

Aw, this was a really quality post. In theory Id like to write like this too - taking time and real effort to make a good article... but what can I say... I procrastinate alot and never seem to get something done.
