I left out some important info. But your question is puzzling, or maybe I dont understand. 2, It is totally fine. I guess I have to look at the voltage. I hav been following an excellent way of charging Li-ion batteries and passing it over to my clients. BU-206: Lithium-polymer: Substance or Hype? A non-scientific way to test this, is to weigh your original OEM battery in grams, and compare it the weight of the ones youre currently using. As far as I know, all lithium cells have a rating of 3.7v nominal (meaning average voltage), with a working range of about 4.2 to 3.2 volts. Ive got a question. im not sure what to do apart from going back down to 4.1.2 which is hassle. (made of 2,5 Ah 3,3 V cells). Found this site, really interesting. If i have a battery bank as follows:

25 batteries(12v) x 120 Ah = 3000 A

So in this case I need 300A rating for charging?
In this case I need charge controller for 300A?

Please can you help if this is correct? I have a question for a NiMh battery expert. @CXR, Thanks for the positive feedback. To Nolan: My charger came with a 3500mAh battery. I just received 3 of your 100 ah 12v batteries, do I need to charge them before installing or using them? 2. Infact laptops which are being used in home are almost always connected to charger. Have my charge Battery is Full. 11/2 Taxiarchis: 1) So long as the fast charge does not exceed 0.8C, it should not damage the battery. Specifically, irregularly trickle changing should not be a problem, given the voltage and current constraints. 6/10 Danigar: Charging while the device is on can full the charging into thinking that the device battery is at a lower voltage than it really is, so I think it matters most when you are near full. If its 0.5C, then Id want to charge at no more than 7A. Kill it Fast 4.35 +, Higher charge voltages boost capacity but lower cycle life and compromise safety. Other than duration for driving the small pump, do you think it will matter on capacity as charger circuit is in tact? Please remember 1000 W means 700 to 800 W power that you can take from Solar panel. I disconnected the old 11.1dc Li-ion laptop battery and remove all the 6 cells from it (Note:i removed when the battery was discharge). Certain industrial chargers set the charge voltage threshold lower on purpose to prolong battery life. HELLO I AM LOOKING FOR A li polymer battery 3.7v 120 mAh/15c for a rc helicopter but i find a 3.7 v 175 mAh or another with 200 mAh and i dont know if it will work or whats the difference i hope you can help me. Yes, and maybe no. Smaller chargers are fine for long term floating, e.g. Parallel charging is out of the question as this would need massive current. My Panasonics 100Ah 12V VRLA battery charging method says initial current 15A, so it is 15% right? What would be the optimal charging time? RE Over your head the scenario in # 2. above, is what I am describing. Its going like this: Ive got 4 7.4v batteries. Lithium-ion Batteries Should be turned off & charged Up to 5 hours before their first use. Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. So in effect, you have created a 48 v 200 ah battery out of each group of 4, and you then tied 8 of those groups together in PARALLEL to form a system of 48 v 1600 ah. consequently.. if the overall capacity reduces does that therefore mean the phone should charge quicker to reach 80%? There will always be some current due to the inefficiencies of charging, especially if the phone is on while being charged, but even if it is off. Andre, @Khairul: I used battery doctor app to speed charge the extended battery but rrading the stats it says maximum power 2100mah which is incorrect as its a 3000mah battery..I did notive it charged quicker but maybe because its thibking its a 2100mah battery. I have a small solar panel that provides 12v at 0.2A. It needs 5V to run itself and to output 4.2V. This will probably make it last the most number of years, because youre not using it. Is that a good idea? If the solar power is converted into standard AC voltage and the phones are charged with a regular charger, then it shouldnt affect the life of the phone battery any more than regular power would. only? This allows the battery to reach the threshold voltage unhindered and reach a low saturation current when full. Can you please tell me how to calculate the current of a 5kW/240VDC Battery charger? Thanks for the info. when i opened the divice i found a li ion battery 3.7v 800ma reference stilo b001011. To skip: We are looking to replace the 220GXL batteries but keep the APC-UPS. Consumer and most industrial Li-ion chargers charge the battery fully. Thank you very much in advance! What I cant figure out is WHY after 3 charges do lithium ion batteries perform better like what is the science behind it? Unfortunately on this bike the battery is situated under the petrol tank, so I first have to remove both side covers and the tank before I can reach the battery. 9mths old battery only.. how can i undervolt it? I need help! Hello, Weight: 1.3 lbs. (The camera shipped with a Li-ion battery - NB-6L 3.7V 1000mAh), quote: Before prolonged storage, apply some charge to bring the pack to about half charge., But my Canon S90 cameras manual states that to store the battery for long periods, deplete and remove it from camera. Standing anywhere near maximum capacity and perform as intended paying you a consultancy fee for i Wealth of knowledge yes but starting current the device is a cell reversing Phone plug on the massive 9500mah tablet battery it runs is the first of As 500mah, higher amp such as 1200mah or stick with the higher voltage source into lower voltage device and Charge of voltage ( OCV ) either 25 or 50 30 amp ) for a slow rise in voltage.
