Yes. However, using a cheap charger, one that has a timer, can damage the batteries and they always cause them to not last nearly as long.

However, using a cheap charger, one that has a timer, can damage the batteries and they always cause them to not last nearly as long. A smart charger measures the voltage among other indicators, to determine when the battery is fully charged. There some really good and/or expensive smart chargers and I have tried a few. Two of my favorites are the Titanium Innovations MD-1600L and the La Crosse BC-500. Both come with a car cigarette plug so it can be used on the go. The MD-1600L also has two USB ports, so I can charge two phones and 16 AA or AAA batteries all at once. Both of these chargers allow you to charge 1 battery at a time or use every slot. I hope this helps someone. see less

Answer:
The Sanyo/Panasonic eneloop cells can be recharged in any good-quality charger designed for NiMH batteries.
For best battery lifespan, choose a 'smart' charger that has a charge time between 2 and 5 hours.

Answer:
Your charger doesn't read each battery individually which is why the jumper didn't work. I like la crosse for their reliability and ease. You may want to look into a delta peak charger that can tell between a drained and bad cell. Read the reviews, some are nearly impossible to use if you use fast charging.

Answer:
I found these to be a fraction wider (maybe 1cm) than typical AA batteries. I would say that if your current box is a tight fit for regular AA, these might pose an issue. If you have some wiggle room with current batteries, probably OK.

Answer:
I did receive 10yrs one. I used the brand-new pre-charged batteries to take pictures. The batteries only lasted for taking two pictures. The claim of "70% charge hold for 10 yrs" probably is not true.

Answer:
These can indeed be charged with the old Sanyo charger, but I wouldn't recommend it because those old chargers needed to charge in pairs. The newer chargers have individual cell charging and will optimize the charge for each individual cell...rather than stopping when one of two in the pair has reached a peak.

Answer:
Yes, you can use them in any device that uses AAA batteries and recharge when needed. I use them in my remote controls as well as a medical device and they work and recharge great.
