- Q: I know that NiMH batteries self-discharge over time, but mine are discharging in just a matter of hours. I am using them in a RC airplane. They are 9.6V 650mah AAA packs. I charge them up just as they should be and they put out full power when I test them in my plane. I go to the gym for a couple hours and stop by the flying field on the way home, but when I plug the battery in the motor on the airplane immediately goes to cut-off.An interesting note: If I hold the arming button down to keep the motor going, eventually it will work itself up to putting out enough power to do some low powered flight and will last the duration over normal flight time for the airplane
- The battery pack is new to you, but it could have been on the shelf in the store or a warehouse for a very long time, easily a couple of years. A single bad cell can ruin a battery pack. 1) One of the cells might have gone bad and can't hold much charge, so it depletes quickly during discharge. The available battery voltage then is 9.6 - 1.2 8.4 volts. As current flows through the bad cell the current reverse-charges the cell, and the available voltage drops to 8.4 - 1.2 7.2 volts. 2) When a motor starts it requires a high current, and this drops the voltage out of the battery due to the internal resistance of the battery. If one cell is bad then the internal resistance is very high. Once the motor is running the required current is less, so the internal resistance of the battery is less, and the battery is able to maintain an adequate voltage. Factories do not test the cells to match their discharge cycles. This can happen to any battery. Car batteries, sealed lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries. extra : This is a huge problem for any large power-storage system, from solar-cell systems to hospitals and server farms. They use large battery banks to give them ride-over time until they can get their gasoline/diesel/natgas generators running. Monitoring each cell in a battery requires special electronics and in the past was not worth the trouble due to the cost. There are now electronic designs that will do this monitoring, but it's not going to be done for cheap RC battery packs.
- Q: Hello Today I Got My Evader EXT RC Car In The Mail With A NiCd Onyx 1800 Battery By Duratrax Anyways On The Back Of The Battery Pack It Says Waring May Cause Cancer Birth Diffects Reading This Scared Me Are They Saying That By Holding Or Handling This Battery Will Cause Cancer I Really Hope Not If Someone Can Give Me Some Reassurance That It's Not Dangerous To Handle This Battery I Will Feel Alot Better If I Knew It Was Safe To Hold And Touch If Someone Can Please Give Me A Answer I Would Greatly Appreciate It
- just dont saw it open and eat the insides :D if its covered in plastic the battery cant harm you. good luck!
- Q: I am using an ACER laptop in particular. So, is it safe to use the laptop when it is directly plugged in (battery pack removed)? I only do this while gaming and i think it preserves battery life if I do this.
- If it is plugged in, it wont rely, because of the fact it is employing your AC adaptor. And if your worrying approximately your getting broken from continuously employing it with out draining it and recharging it in cycles, you ought to purchase a alternative battery on amazon and OKorder for approximately $20. they're aftermarket, yet i'm getting approximately 3 hours out of one i offered for my dell.
- Q: I have a red controller, I want to buy a new rechargeable batter pack. I bought the red controller like the week it came out, so I have used it a lot. Now I have to charge it like every 2-3 hours and that is getting pretty annoying. If anyone can help me find a place to buy a new one it is okay, if they don't sell what other colors would look good with the red. I think there is white, black, blue, and pink.
- i bought mine at best buy and i don't think there's a red one but i bought two black ones (sold together) and they are great. I mean i can play for a couple days and they wont die. It also only takes an hour to fully charge both of them
- Q: I have a small rc helicopter, loads of fun btw, and I was curious if I could add another, identical battery to the existing one,and fyi the heli could handle the extra weight, no problem.
- in case you boost the amps draw (modern-day) the amp hours will shrink by way of warmth waste, and the character of batteries, additionally i think of that score is like under optimal situations, like low draw for long term. in case you upload extra cells in sequence to extend the volts the motor rpms will boost and so will the stall modern-day which may make a lot of heat and torque. Dc autos are rated amps at finished sustainable load at rated speed. The torque is without delay proportional to amps obtainable and speed is without delay proportional to volts obtainable you could double the skill %. in parallel and get extra torque and battery existence. You did no longer state your application so i won't be able to furnish extra suggestion. with the help of ways it is alright to overload dc autos severly for brief sessions of time without severe effects, yet like an engine, it does shorten the existence.
- Q: I drive a 2000 Lexus LS400 I was told a sedan consumes less amps than a SUV or pick up
- There's okorder
- Q: I was thinking of buying a rechargable battery for my controller cuz my regular batteries die fast. So i was wondering if they work. Should i buy rechargable pack or should i just stick with the regular 2 AA batteries???
- buy energizer battery pack so u can charge 4-8 batteries at the same time more power less price safe coz tht thing eats up ur 360's power
- Q: i have the old note 10.1 (not the 2014 edition). i was wondering if anyone knows of a good battery pack/portable battery/external charger for the note 10.1. i read that some battery packs only charged the tablet while it was off, and i need a battery pack that will charge my tablet while it is on and i am using the device

- Q: I have replaced the ni-cad cells in my 18V bosch drill with li-ion cells (respecting the voltage and wiring).Can I use the original ni-cad charger?The charger knew when to stop charging with the ni-cad battery, will it do the same now?Thank you.
- If you can stop a 300 ft pound impact wrench it isn't worth owning unless there is a torque setting and you have it on the weakest setting. Regarding the batteries, tools are usually one or the other meaning that if it comes with NiCad or Li Ion there is no switching to the other or why would they produce two batts for the same device. If you HAVE a choice Li ion batts are very light in weight by comparison to 18V NiCads are. I have two cordless drills I use/used. One is an 18 volt DeWalt with NiCad and the other is Rigid with Li Ion, they are both the same relative age ( maybe 6 months between the two) . My DeWalt is still going strong 8 years later, but the Rigid with compact Li Ion batts are BOTH dead and gone: no recharging will kick them over. I called customer service to see if I could find out whether it was the charger or the batts. They weren't any help so I got another charger and the batts came up as defective. At $100 each I am in no hurry to replace them because the DeWalt is still going strong. So I am convinced Li Ion is one I personally will avoid going forward.
- Q: I have a motorola handheld radio when i put the battery in the charger it will rapid charge for 1hr then go to trickle charge how long should i leave it in the charger i have been told 2hr after rapid is done and told 12hrs the packs cost a bit so can someone please help so i dont mess them up thanks
- The issue with long charge times is heat. When you charge a battery, either using a fast charger or slow charge, the power going into it reverses the chemical action to the state it needs to be in to produce electricity again. When the battery is charged, the power going into the battery simply turns to heat. If the battery gets too hot it will vent to prevent it from exploding. This venting of gases means the battery can't work as well or it might not work at all. A slow charger usually charges a battery at 1/10 or less of it's rated capacity. This is low enough that the battery can be charged indefinitely without getting too hot. When a fast charger switches to the slow mode, it's at 1/10 or less of the capacity and this won't cause any heat problems.
