About batteries, I tried car recharging with lowest specification mentioned as effective rechargeables and it did not work. Stronger batteries?

You did not say what batteries or charger you are using so it's impossible to tell why you are having trouble. I use NiMH rechargeables. The silver Energizer's seem to last longer than Duracell's but both will power the unit for a day's use.

The Dakota (and Oregon) models do NOT provide for recharging batteries while in the unit. A DC power supply may provide supplementary power while you're in your vehicle possibly extending internal battery power somewhat, but I get 6-12 hours pers use on one set of fully charged NiMH. Personally, I carry a spare pair of charged AA's AND a pair of alkalines just in case.

You might also try using rechargeable batteries. I use those exclusively now. For whatever reason, they just seem to work a lot better.

I have'nt used rechargable batteries with it but can't see why they should'nt work.

These batteries work great in our club car. The batteries are much smaller but have plenty of power. All the batteries actually fit on one side so now I have extra storage where the other batteries were. Hope this helps

As far as cold weather performance, I'm now disappointed. I tested it today with both the car and the just-charged powerall cold, at -15°C (5F). It doesn't work. But there could be something wrong with mine and maybe it's not fully charged. While charging, it stayed at the 3-led level for 4 hrs. So I dis/reconnected charger, and suddenly it goes to 5 leds and stops. Something's weird.

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.

Any rechargeable AA will work. The ones with the higher mAh ratings will likely hold a charge longer. I've used different brands without noticing much difference. I would just avoid the cheapest, unknown brands.

Please check your batteries, the batteries might be low. If you use high power on these types of flashlight they use up a lot of battery power.I use for my flashlight UltraFire18650 3000 MAH from Battery Junction website. 3000 MAH is the reserve battery power. It is like the gas tank of your car. The lower the number, the less reserve battery power. Be careful by these batteries from E-Bay there are a lot of FAKES, I buy my batteries from BatteryJunction Website. I hope this helps good luck

With all due respect, it's more a question of: "Will the batteries survive the temperatures. If the car is in a garage there's a good chance of success. If it's outside all the time I wouldn't want to depend on working batteries or flashlight. I would call the manufacturer of the batteries you intend to use and ask them. They can be much more specific.

Regular aa's will work but I used rechargable. I do not recomend this product

i've used it with both rechargable and AA batteries. the AA worked for me, but had two negatives in comparison to the rechargables: it felt heavier, and the battery life was shorter. if your adapter for the AA isnt working properly, it might be the unit. have you tried using the rechargable batteries?

I actually didn't use rechargable. I used regular AA and it worked perfectly for me!

Keep in mind that a defective charger will give the same failure symptoms as defective batteries. The charger can be tested with a voltmeter or by connecting 2 car taillights in series and light them up with the charger.

Michael, because these are Nickel Cadmium (Ni-Cd), they have a memory. In other words they remember how low their charge gets, before they are recharged, Charging them too soon, will prevent you from getting all the battery has to offer. Try to charge them when they get very low. That way you'll get the longest life from them. Keep in mind that the hotter the batteries get, the more internal damage occurs. Try not to let them get too hot. Their life cycle will be shortened. Use them, charge them, and then use them again is probably the best bet, unless you have some sophisticated temperature, current and an adjustable charger at hand. Norm

If you use an alkaline AA battery then you still get 1.5v but you won't get the energy density of a D battery so it won't last as long under the same power draw (amperage). Some device have a large power draw to begin with and it can exceed the specifications for the AA cell. In that case, the AA cell appears, "weak". If you use rechargeable AA batteries you get even less time before you start running at voltages far less than 1.5v. Most rechargeables start at less than 1.5v to begin with.

i really dont know for sure, but i own a car lot so i use mine evryday serveral times a day and i can recharge one a lot of times , before i have to have a new one,this is about my fifth one and i have tired other brands but this is the one i always come back too
