How do you know if a rechargeable battery is NiCD or NiMH there are only mAH markings on the batterys and both are 7.2V packs made up of six 1.2V units one is 1600mAH and the other is 3000mAH?

Looks like both are NiMH as NiCd batteries are generally not available for more than 800mAH rating. NiMH are common to have 1600mAH and more rating per AA cell. - Neeraj Sharma

What rechargeable batteries have the longest shelf life?
Energizer recharable batteries offer the best charge the longest.
What is the difference between 900mAh and 3000mAh batteries?
The current relates to the flow of electric charge in an object. Basically the Ampere hour is a measure of how 'long' it will last for. So a higher amount will result in a longer lasting battery because it 'contains' more current.
How do you balance the lipo 3000mah 3S 11.1v battery by using imax b6 charger?
Wait until the battery gets warm. Then use an amp measured to figure out the right number of amps. If that doesn't work then just take it to a local hobby shop.
How long should 4 AA batteries last using a 3.4 volt LED combined with a 150 ohm resistor if used 10 hours a day?
If placed in series, DC current will be (when the LED is fully on, assuming a .7 volt drop): I = (1.5 volts per battery x 4 - .7 volts) / (150 ohms) = 35.3mA So each day, there is a requirement for 35.3mA * 10 hours = 353mAh Depending on the battery, this may last for several days on to several weeks. Cheaper batteries hold less charge. Also, many batteries have 1.2 volts per cell (such as lithium batteries). Each day would require ~273mAh. Rechargeable batteries range from 600mAh - near 3000mAh for AA (last time I looked), so again a good estimation would be a 2 to 11 days.
How long does it take to charge a traxxas slash battery?
The battery life all depends on your driving. For example the Traxxas Rustler VXL's battery life will get about 20 minutes (Still depending on how hard it is driven). But don't think that 20mins is nothing, its actually pretty good for an electric r/c truck.
How much time to charge 3000mah battery?
The milli-amp-hours rating has nothing to do with the voltage. The rating should be something like 3000 mah at 12V or 3000 mah at 1.5V. One common 3000 mAh battery is 3.0 volts; another is 3.7 volts. A common camcorder battery is 7.4 volts. Some DeWalt tools use 12 V 3000 mAh batteries.
How long does it take to charge an 8.4v 3000mAh NiMH battery?
It takes 9 hours 10 minutes to fully charge. Sometimes the wait will be longer, sometimes shorter. If you just used a battery for a short time, than it won't last 9 hours to charge. If you used the battery fully than 9 hours is the time it will take to charge completely. Every battery is different, and some may take longer.
Is the stock 8.4V 3000mah battery that comes with the Traxxas Slash waterproof?
i just got mine today and its been raining non-stop. aas ive been driving my slash non-stop with the stock battery as well. its been working just fine all day. it looks like moisture IS getting inside the the cover layer of the battery so idk if it will still work tomorrow or not. i put it up to a fan to dry it just to be safe. just be careful my friend!
How long will a 1500mAh battery last?
Depends on the drain. if the drain is 1500mAh it'll laso one hour before the voltage drops too low. If the drain is 500 mAh it'll last 3 hours. 150mAh, 10 hours 3000mAh, 0.5 hours.
Suitable battery for canon A 1000 IS?
Canon A1000IS is AA battery camera. AA battery camera is the most suitable for High capacity NIMH battery.Because,the working current of camera is very large, nearly 1000mah.For examples SONY DSC-P92,Maximum working current can reach 1350mah.This kind of electric appliance is the higher requirement to the Load capacity of battery. NIMH battery has better load capacity than Alkaline battery. So AA battery camera used NIMH battery can take more photos. I have done the experiment and collect many data from different people different cameras. I can draw the following general conclusions. If you have interests,you also can go to check. If the camera can takes more than 10 photos with two AA alkaline batteries, the camera can flash photography more than 1000 pieces with two AA 2300MAH NIMH batteries. If the camera can takes more than 200 photos with four AA alkaline batteries, the camera can flash photography more than 1500 pieces with four AA 2300MAH NIMH batteries. And the data of the camera with four batteries is more accurate than the one with two batteries. The following series FUJI S2500,FUJIS2600,FUJIS2900,CANON S2IS,NIKON L100,L110,L120 both can reach the good effect. But the charge of NIMH battery is really a problem. Now,NIMH battery changer usually use constant voltage source. The way always cannot charge sufficient NIMH battery fully. Because the charging current of the constant voltage source can change. It detects the characteristic of battery to determine sufficient. But when the NIMH battery is charged sufficient, the characteristic is different. Even the same battery can produces different characteristic when it is new and old time.So it is difficult to charge sufficient battery with constant voltage source. The constant current cource is good way to charge NIMH battery.The charging current of constant current source is constant.So if we know the capacity of battery and charging current,we can calculate the time of charge.We control the time of charge,We can control the total input power.So any battery can be charged sufficient. If 2300MAH NIMH battery can be charged sufficient, you can flash photograph more than 1000 pieces. Now, constant current source battery charger is vey rare. The best is in shanghai china,call "tianyuan",in china called"天元".The company is specializing in the study of variable constant current technology enterprises. "tianyuan" battery charger has 4 grades of constant current source,from 300MA-150MA-70MA-35MA,which can charge 150mah-3000mah range NICD,NIMH battery,the charging current is not charge according to number of battery,and 1-15 hours digital timing control which the precision is very high. "tianyuan" also writes some importmant articles about battery and battery charger.If you read these articles,you will konw more knowledge about this area. Above the camera shot of data is just from the shanghai tianyuan. Finally, I am sorry ,my English is not very good. If something you can't understand,you can e-mail to me.I will do my best to answer you.
What is the fastest electric RC boat on the market?
Most everyone will imply that you mean RTR, correct? Of rtr's, brushless electrics will be the fastest also the most expensive. Some of the more popular ones are ProBoat's BlackJack 26 brushless, fastech brushless, their brushless elam, and their new brushless boat. Aquacraft is also another very popular brand name. Their sv27 and UL-1 brushless boats are very fast. Aeromarine puts out a few high priced models and minicat racing has some models that are extremely fast. When looking for the "fastest" there are several factors to consider. Hull type, battery type, motor, speed controller, prop, and water conditions. For example, a hydro hull will be faster than a v-hull but you better be on very calm water with a hydro or it go airborne; where as the v-hull will be able to handle rough water the best. Also a v-hull will cleave the water and turn sharper that a flat hull will which will slide in turns unless a turn fin is added. For power Lithium Polymer aka LiPo are lighter and put out more current to weight than Nickel Metal Hydride aka NiMH's do and last much longer, however they are also more expensive. The advantages of NiMH are that each cell is at 1.2volts at charge while LiPo cells are usually at 3.7v per cell. For instance a 6 cell NiMH standard pack is 7.2v while a 2 cell LiPo is 7.4v. The advantage comes into play when choosing power setups. For example, Lets use the SV27. If we have 2 sv27's one with 2 7.2v NiMH packs and one with 2 7.4v LiPo's the LiPo boat will go at least 5-7mph faster than the SV27 with the NiMH's. But add a cell to each of the NiMH packs making them 8.4v each and the LiPo SV27 will no longer be the fastest. If you were to do the same thing to the LiPo's by adding a cell, now each LiPo pack is 11.1v combined for 22.2v!!! The SV27's motor and speed controller will fry. If you like building then you can get your custom boat to go as fast as the hull can handle. The current world record is a rigger hull at 146.7mph!!! I'm currently building a 40inch V-hull with a large Brushless electric set up. The motor is a 12 turn 45mmX77mm Brushless watercooled motor with a 120amp water cooled speed controller or ESC. I'll power it with a 8s LiPo (2 14.8v 5000mAh 35c 4s1p LiPo's in series) for a total of 29.6volts!!! I'll be using an Octura x452 prop. I'm expecting over 70mph!!! I also have a ProBoat BJ 26 BL I'm running 2 7.4v 4000mAh 25c 2s1p LiPo's. My BJ goes about 45mph with the LiPo's. I've also modded an old Cen Baja that came with a 550 brushed motor. I added a 775 brushed motor with a Navy 60amp brushed ESC. This boat moves at about 35 to 40mph with 36mm 2-blade prop I added to it using a 14.8v 3000mAh 35c 4s1p LiPo pack. In conclusion, if you are looking for the all in all fastest mass production Brushless r/c boat I'd guess it would probaby be the New Aquacraft UL-1 as it is a hydro hull running on 2 2s1p 7.4v 25c-30c burst 45c-50c 3300mAh - 5000+mAh LiPos. I heard about 47mph!!! I don't own one YET so I can't say for sure.
