Yes you can, but using normal rechargeable NiMH batteries will mean that the batteries will go dead pretty quick even when the headset is sitting there turned off. This is due to the self-discharge problem that normal rechargeable batteries have. The batteries you should use are Precharged NiMH batteries. You can find them sold under many brand names as "Precharged Rechargeable Batteries" The best known brands are Sanyo Eneloop and Sony Cycle Energy. Amazon carries these kinds of batteries. They're also available at Costco and some electronic stores. These headphones included Sanyo Eneloop batteries standard. Precharged Rechargeable batteries do not loose their charge over time as fast as normal rechargeable batteries. Normal rechargeable batteries will loose 20% of their charge in the first day of storage. While Eneloop (or precharged) rechargeable batteries will take about 2 years to loose 20% of their charge when stored. Note that having the headphones sitting off the charger counts as storage. It's also possible that the charger for these headphones doesn't continue to trickle charge after the first charge is complete. So even having the headphones sitting on the charger probably counts as storage. Which is why Sennheiser choose to ship Eneeloop batteries with this headset.

No not that I'm aware. Batteries last a long time. And quick :15 recharge makes swapping batteries a breeze for larger jobs.

No. I tried the same thing. But there is circuitry to prevent overcharging which would damage your batteries that is missing in the circuit.

Any AAA batteries should work, but like another commenter, I recommend using eneloop nimh batteries. They actually last longer than alkaline and you don't have to worry about leaks. Plus they're rechargeable, and this thing eats through batteries fast.

I haven't specifically used these batteries for your purpose. I have, however, used them for XBox controllers, TV remotes, a battery powered razor, battery powered clocks, my home thermostat, and RC cars. In every case, the performance of the rechargeable batteries has met or exceeded the performance of standard batteries. Rechargeable work well enough that I haven't purchased a standard battery for a couple of years.One recommendation I would make though, is to buy a few more batteries than you need. This way you can simply swap the discharged batteries for some newly-charged ones right away. I know that I didn't answer your question directly, but hope it helps.

A battery of the same size will work (AAA or AA). Get a lithium replacement as they work well in slow drain devices like a mouse. You will need to have another set of batteries to maintain uninterrupted use of the mouse. If you decide to use rechargeable batteries as your replacement set, charge them at the end of the first set discharge time. All batteries drain while on the shelf. Rechargeable batteries drain more quickly than disposable batteries. Some rechargeable batteries may be permanently damaged if allowed to zero if left on the shelf.

the unit takes standard aaa batteries.uses very little power so i would not use rechargables as they discharge in the unit.

Yes, But it will be a long while for that. I worked for AAA for a little over a year and never had to put a new battery. I used it over 2000 times in a year. Now that I dont work for them anymore I got myself one of them for myself. Link for battery on amazon.com 12V 18AH Replacement Battery for Jump n Carry JNC660 JNCAIR JNC 660 JNC4000

Oh, thanks for clearing that up for me. But I'm kinda worried that they aren't replaceable. I've seen a few batteries die completely in a state where they aren't even rechargeable anymore. I hope these lithium batteries last if you can't replace them.

not sure, these batteries are made to recycle (recharge) as long as you have the correct system that will not let them over charge and not let them set with out charge for long periods of time they should be fine. I would contact the manufacturer. Hopes that helps?Darryl

James, really don't know much about re-chargable batteries, so I am sorry I can't help! Other reviewers may have the answers you're looking for.

Remove and re- charge. We simply used replaceable alkaline batteries in our circumstances. Did not use rechargeable batteries.

Yes, you can replace the rechargeable batteries with regular alkaline or even heavy duty batteries. Just don't try setting the headphones on the cradle with regular batteries, it could damage them. Only use rechargeable batteries if you are setting the headset on the charger.

You can use any brand of rechargeable batteries, otherwise if you use it much you will be wasting a lot of money on throw away batteries.

We use rechargeable AAA batteries with no problems. Makes sense to us because regular batteries won't last very long and will be expensive for you. We've had our set for almost a year and "knock on wood" they work just fine with the rechargeables.
