I have always had good results from eneloop batteries. I have a set of four in all my flash units (8 flash units in total), I have spare sets, and I use them in anything else that takes batteries. When I charge them, I do it at the slower rate -- takes 2 hours. Best of luck.

We did a study on batteries in my electronics class. One of our conclusions was that you do not want to purchase and use Duracell, and especially Ray-O-Vac batteries. Due to their construction, they are much more prone to leaking than othe brands!

I seriously would not be surprised if someone has seen 'Enloop' on some knock-off batteries! Some really shady battery producers in the boonies of China also produce batteries. There are some great producers there, too, but sometimes you take a chance. I've been burned once.

I use Ray-o-Vac AA alkaline by the dozens. They don't stay around long enough to leak.

Key: Don't leave batteries in devices that are idle for more than a month!

I use a Canon 600EX-RT flash and when I start out with 4 freshly charged white (lower rated mAh) Eneloop batts I can shoot an entire assignment w/o changing batts. At the end of a 200-300 exposure shoot the recycle time is still acceptably short. Even shooting outside in bright light and using the fill flash function the number of shots remains high and the recycle time remains short. Until someone can demonstrate a better rechargeable batt, I will stick with Eneloop. This is my experience. Thanks, JimmyT

Keep in mind that the standard Eneloops and the Amazon Basic models are the lower mAh rated batteries. The Eneloop Pro and IKEA Ladda batteries are the higher rated mAh batteries. This may or may not be of importance to you. It depends upon the application you intend to use them for.

That's 2 solutions, Use alkaline batteries quickly before they leak (Valid but expensive) or don't leave batteries in your device for more than a month (probably also sound advice) The original question though was: Has anyone EVER had an Eneloop battery leak? They tout on their packaging that they hold 70% of their charge for something like 10yrs. Doesn't that imply that if it hold its charge for 10 years that it probably wont leak for 10yrs?

I confess I get lax and don't always remove them. I'm now questioning if maybe its okay to leave them in for months or even years.

Been using Eneloop batteries for years (both Sanyo and Panasonic) in my flashes. Never had a leaking issue or any other issues. The recycle time is fast on my flashes. Some of these batteries are many years old and still charge to their fullest....Pay a bit more upfront and save on the back end!!! Eneloops will always be in my camera bag.

I thought eneloop was a Sanyo product.

Other manufacturers?

They were a Sanyo product. Panasonic bought them out.

I use Eneloops in high drain, frequent use devices that tolerate the slightly lower voltage of NiMH chemistry. I use alkaline cells when I need an honest 1.5 volts, as in certain game system remotes, Apple Mouse, and wireless microphone systems.

By five years, most small rechargeable batteries are showing age. I usually pitch ‘em in the recycling bin by then.

The alkalines will not give an honest 1.5 volts. They immediately drop once a load is placed on them.

Then why do they work for eight hours in a wireless mic transmitter, but freshly charged, nearly new, broken-in Eneloops only last an hour?

The reverse is true in flash units, where alkalines are wimpy, compared to NiMH cells.

I have several pairs of Eneloops I rotate through an Apple magic mouse (the one with the trackpad built into its top) and they last a bit over 2 weeks before I get a low charge warning. I do use it a lot and leave it on all the time. The separate Apple Trackpad, which I also leave on all the time but rarely use, goes 1.5 to 2 months before warning it needs new batteries. (The Logitech wireless mouse that's for the Windows 7 box is also on all the time and almost never used - it's had the same 2 alkaline batteries in it for a couple of years and still says it's well charged.)

My experience with Eneloops in wireless radios and mic transmitters is the opposite of yours. My Eneloops last considerably longer. The Eneloops hold a steady voltage. While alkalines have a steady drop off until they quit on you. We’ve done extensive testing on this subject in our electronics lab. Have you load tested alkalines and Eneloops? Conduct a load test with alkaline and Eneloops, with a DMM in the setup. Let us know what results you get.

Thanks

All I know is, I was burned twice with two different sets of NiMH cells in my Sennheiser G2 transmitter and receiver.

Sennheiser specifically says to use ONLY their BA2015 Accupack rechargeable pack, which contains circuitry to account for the voltage differences and drain characteristics of the different chemistry. They are not kidding! The Accupacks worked fine, for about five years. When I tried replacing them with eneloops, they died in the middle of an important job.
