If a device uses alkaline batteries, but can be connected via an AC adapter. If I replace the alkaline batteries with the Amazon Ni-MH batteries, will the AC adapter charge the Ni-MH batteries while they are still in the device?

I would say that it depends on the device, but most probably not. A device that by definition uses alkaline batteries for example a portable stereo usually just cuts the batteries off from the circuit once an external power source is plugged in because otherwise there is to great a risk of batteries exploding and it's very expensive to build a necessary circuity to detect the exact kind of batteries being used. So it seems improbable that the batteries will be charged from an external power source.

Any device with a display will eat batteries. You must use nimh rechargeable's. Most people already have AA/AAA chargers in their home for other things. Get 8 AAA NiMH Hybrid batteries, 4 for use and 4 for swapping. Hybrid batteries are also labeled PreCharged on retail blister packs. Sanyo's Eneloops here on Amazon are excellent choices. Hybrids will not self discharge like standard NiMHs.

No, AA NI-MH batteries put out about 1.2 volts. So they need to be charged at about 1.4 ish volts, this charger would overcharge the batteries

As with any battery powered electronic device, performance will vary with use. However, with the rechargeable Ni-MH batteries you should have the flexibility of quickly recharging during intermitant use.

Apologies for such a late/delayed response. ALL of the listed rechargeable batteries AA/AAA/C/D/9V are handled, and BOTH types, the Nickel Metal Hydride (NiMH) and Nickel-Cadmium (NiCD). I have been using it for quite awhile now, and this unit works wonderfully. But, I will HIGHLY RECOMMEND to anyone, spend a little bit more money on the Nickel Metal Hydride (NiMH) rechargeables! They last about two to three times as long after recharge than the NiCD type. Just a suggestion :) :) :)

It depends entirely on the type of battery. This holder allows AA batteries to be used in place of the rechargeable Li-ion battery. If you use NiMH rechargeables you will get a similar number of photos. The real advantage is that you can use alkaline AA's which are widely available -- even in remote locations.

It says in the back to charge only Panasonic 1-4 AAA/AA Ni-MH type rechargeable batteries. Of course they would say that in order to sell their batteries. I don't see why you cannot charge other Ni-MH batteries. Note that I have only used it for Panasonic Eneloop myself.

The unit I purchased (MH-72/EN-MH2-B2) came with an ac adapter. It doesn't make a lot of sense that it wouldn't ....how would you charge the batteries without one?

I just got mine and couldn't find where it said not to use rechargeables, tried N-MH batteries and it worked fine. All 4 modes OK. I would rather use rechargeables since have had Alkalines leak and ruin things the last 3-4 years, (new ones ). I'm talking major brand batteries too. Maybe Chinas' Quality Control has dropped.

No - according to the back of the original package, only Ni-MH batteries should be used in the charger. I hope this helps!

Yes. If the DC adapter is plugged into the 110 wall circuit & the DC input of the radio ** and the power is ON, the (6 C) batteries are just ballast (it works without the batteries installed as well). Once the adapter is unplugged, power is switched to the batteries seamlessly (& vise versa). If the adapter is plugged in and the power switch is OFF and there are rechargeable NIMH C batteries in the radio and the battery switch is on NIMH, the batteries will be charged. If the batteries are alkaline, the battery switch must indicate Alkaline so the unit does not attempt to charge them. ** The DC input is 12V 700 mA... so any adapter (120V to 240V) that produces the required DC output should work fine.

Per the listed info and the charger label customer photo, NO. This is a NiMH and NiCad charger which can also partially revive alkaline batteries which I have almost given up using due to their well known leakage issues and lousy high current capability. Use alkalines in a $100+ high power flashlight, NO WAY! Unless a charger specifically Lists the ability to charge Lithium Ion batteries then it will not do so. Their high voltages and wide ranging chemistries mean that only a few specific chargers can even handle all commonly available versions of Lithium Ion cells. The XTAR VP2 charger can handle almost all Lithium Ion chemistries and voltages but is not NiMH & NiCad compatible. Per the listed info and the charger label customer photo, NO.

The unit calls for an AAA Ni-MH rechargeable battery, however there is a small tag within the unit that states to use JVC replacement batteries. These cost about $24 shipped for a pair. The unit WILL work with standard Ni-MH batteries with the following simple fix: Trim the plastic wrapping 1/4" off the bottom (negative side) of the battery just like the original ones are. There is an internal contact within the headphones that it makes on the battery edge and not on the end as would be expected. JVC came up with a simple method to make certain we only use their batteries.

I have different usb wall chargers, and the batteries charged ok with all of them. They also charge when connected to the pc's usb. Pay attention to the current the charger may provide (notice the mA or A value on the charger. If it's too high, the battery may charge faster, but you risk to damage it.)

This charger CAN recharge NiMH batteries as well as the included Alkaline batteries.I wouldn't try standard disposable alkalines, but I use it for my sizable collection of NiMHs as well - in fact, I bought it to replace a failed charger that blew up four of my newer NiMH batteries.

I also use SONY NI-MH batteries and I haven't experienced any problems. I think what they meant to emphasize was to use NiMH type of rechargeable batteries. Here is what Olympus recommends: Ni-MH Quick Charger and Battery Set (B-90SU) http://www.olympusamerica.com/cpg_section/product.asp?product=1393&fl=5 "What is the difference between Nickel Cadmium (NiCad) and Nickel Metal Hydride (NIMH) batteries? Both NiCad and NiMH batteries are rechargeable. The main difference between the two is the fact that NIMH batteries offer higher energy densities than NiCads. In other words, pound for pound, NIMH delivers approximately 30% more capacity than its NiCad counterpart. " Reference: http://www.batterymart.com/c-battery-facts-faqs.html#lith-alk

No, and it only does a marginal job on alkaline batteries. I have charged over 100 D, C, AA, and AAA alkaline types and they rarely achieve over 50% energy density of a new battery. Don't expect the recharging ability of a NiMH or a NiCad on an alkaline.
