I personally would charge it out of the device because in reality a chsrging device is man made and man is faulible a human makes mistake. I would take the time a charge the battery seperately.

I don't think so.The device should have a "charge" function for that to work. The AC adapter usually provides DC to the device and bypasses the batteries. You need to check the device instruction manual..But in lieu of that.. I would not count on it..That said, you should be able to to use the NIMH rechargeable in place of the alkalines but you will have to recharge them in an external charger.

Not unless the device is made to use and recharge rechargeable batteries, so the answer would be no unless it was made to use rechargeable batteries to begin with.

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.

It will recharge rechargeable batteries, including the batteries that come with the charger. I would not expect it to recharge alkaline batteries.

It's a cell not a circuit. I use only Li-ion and Li-Polymer 9 volts on about 20 projects that continue to run to discharge with no problems; a smart charger exclusively for these batteries has the circuit that has yet to fail to charge any of these 'over-discharged' batteries. Most electronics stop working at a certain voltage long before the battery is totally discharged. Still, even with current-hungry circuits, none of the 40+ various lithium 9 volts I use for the last year and a half have failed with constant charge/discharge.Can't say the same for NiMH.

NiMH batteries are reuseable - for this one $6 shot = about a dozen AA alkalines over 4 charges e.g. http://www.amazon.com/Energizer-Instant-Charger-Mobile-Phones/dp/B0093GIME8

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.

It does not. In my opinion, it is beneficial to have the versatility to be able to use standard batteries. The battery makers all have rechargeable batteries now, so you could go that route and still have the option to use alkaline or lithium off the shelf batteries in a pinch. It's just a lot easier for me to carry extra batteries (although the run time on this lamp is very long) than carry a charger and worry about a power source. Just food for thought.

no, because in order to check a non rechargeable battery you have to charge that battery first. And you cannot charge alkaline batteries.

If it works you can ( Though manufacturer does not recommend it ). The charger does not work most of the time. It keeps showing every battery "BAD". However, there are much cheaper chargers available on AMAZON to charge NI-CAD and NI-MIH batteries.

We're still using the battery that came with the brush, so I haven't tried. We had an older version of the brush and they worked in there. I believe most items use NI-MH or NiCad AAs as if they were just AAs. As far as I know, the only difference is in the charger or charger settings if you have a multi-charger. The ultimate benefit of rechargeables is that they are interchangeable and "green" as far as frequency of disposal.

It can use alkaline or rechargeable AA batteries, but has no external charging capability. You have to remove the batteries to recharge them, if you use rechargeable ones. They last a long time, though, so it has never been an issue.

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 believe that you can use alkaline AA's in a pinch, but they won't last very long. I've always used Lithium AA's or NiMH rechargables.

Edward Shimkus' answer is right on target. I have yet to even charge the supplied Sony Ni-MH batteries included with the charger. However, I have recharged a number of times some old Duracell (2650mAh-not high capacity version) Ni-MH batteries with excellent results, including using the "refresh" function provided by the device. I'm very satisfied with this device and feel it is well worth the price.

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.

You can charge any brand as long as it is Nickle Metal Hydride. You can also recharge Alkaline, but that kind should be completely dead to avoid the "memory" effect. Truly, Hank

These batteries can be charged with any charger that charges NiMh batteries. It should say that on the charger's package. When charged, you just use these batteries like any other batteries, based on the size. For example, the "D" cell batteries can be used on any appliance that takes "D" cell batteries.
