Later on at home, my main charger discharges them and then charging goes on, which fixes their memory to normal if they are smart. First I place them into a TV or video remote control. When they stop working there, then I use charger. Please help me. Thank you very much in advance. Hello Somi, Could you supply 3 additional kinds of information for charging those batteries in twos, as the needed info is missing.
I have a RC helicopter but the battery it uses takes forever to charge and then allowance is approximately 10 minutes time of flight consequently having have to recharge the battery again and again. The battery specs are 3. My question is if I buy a 3. How long time does it take to discharge a rechargeable battery in question. Specifications of the battery:.
I have developed a charging ckt that I can set the charging current to any value from ma to 1 amp. At 1 amp my circuit shuts down in 5 minutes and disconnect the batteries from the charger. All the batteries test good on a load tester. I can with these set up conditions, charge several 1. Question: Is one amp to much for recharging?
I have 3. What kind of energy harvester do you have, is it a circuit or something simpler or more advanced? Anything renewable? That is interesting concept. If it produces 3. Let me know, I could calculate the numbers for this.
Vince, Do you mean 1 amp for 1. Awaiting your prompt action. I was hoping a website like this for charging times would exist. The information this page provides is extremely helpful to me as I have quite a large variety of different rechargeable type batteries to charge. Also I find building my own specific chargers to be a lots of fun. I have been using LM etc. I never rush any charging time. Thank you very much for putting this web page together.
It has to be the exact power BT 3. Thanks, Rose. Greetings, I have 2 lie on rechargeable batteries , mAh 3. My question is….. Will this charger fully charge the batteries to there full potential? They seem to be a high quality batteries. For the time being it could work. I have a Minelab Slimpack nimh rechargeable battery pack This calculator does not give a correct result. I think this is because of a stray multiplier you introduced in one of the formulas you use. Follow the manufacturer's recommendations for sending in your charger for service.

Battery Charging. Candlepower Forums as well. There are some Li-Ion family battery chemistries which are much safer. Lithium-Manganese, and Lithium-Ferro-Phosphate, for example. The primary difference is that the lithium-salt electrolyte is not held in an organic solvent but in a solid polymer composite such as polyethylene oxide or polyacrylonitrile.
The wikipedia article further mentions that the positive electrode is either Lithium Cobalt or Lithium Manganese. Of these 2, the Cobalt salt is the common Li-Ion material, and so any Li-Poly battery using such chemistry will not be inherently more or less safe than other common Li-Ion cells.
There's a reason why you can find 'protected' Li-Ion batteries. The manufacturers of these AW, Tenergy, Ultrafire, etc. But these protection circuits can fail too. In a mobile phone, the battery is a Li-Ion, even if it's a Li-Poly configuration.
The overcharge protection circuit is included in the phone's electronics. The protection circuit should also protect against over discharge, both in terms of excessive discharge, and overcurrent.
I don't use common Li-Ion cells at all except in my phone, where I have no choice, and in fact I don't know specifically what chemistry it uses ; I use LiMn, and will probably be using LiFePo in the future.
I also use a Pila IBC charger. Lots of people this is from the e-cig forums, and flashlight forums don't trust the cheaper chargers to shut off. Similar to a couple recent threads we've had here on el-cheapo DC-DC converters.
Also, as I understand it, lithium fires can't be extinguished with water. So buy a good charger. If you want to be really, paranoid, there are Li-Ion charging bags.
