These cells are our largest capacity NiMH cells; they are built for supreme performance and provide the power and durability needed for all applications. NiMH batteries provide the perfect starting point for beginners or users who are unsure of lithium. NiMH packs provide huge power and durability for high drain applications.
They are most commonly used in receivers and transmitters and give exceptional results and running times. The NiMH chemistry is improving by the day; they are effortlessly maintained with easy management and care. These key features make these rechargeable batteries an extremely popular choice.
All our NiMH packs are manufactured using pure nickel tabs that are either double or treble tagged. The gold pins within the plugs make for perfect contact with the application which, when working in conjunction with the multi-strand silicone leads, are able to carry high currents.
This ensures no power is lost through the interaction, so your packs provide full power throughout use. Overlander's UK-based factory facilitates ultrasonic and capacitor resistance welding machinery. Having advanced equipment ensures that all of our highly trained operatives create the most efficient and precise NiMH battery packs to suit all of your applications.

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. You state the theoretical formula for calculating the time it would take to charge given that charging commences without losses at a constant current :.
What does it represent? You can check your calculator by setting the capacity to mAh and the charger current to mA. This should give you 1 hr, but your calculations point at 1. It needs to go further. But do not confuse this 1.
Even though the Ampere is actually a SI unit of current being transited per unit-time. An average, instantaneous and constant current are expressed in Amperes e. How to calculate life time of rechargeable battery?
How many years a rechargeable battery can work? Also, the charging time calculated is varies depending on which battery type is selected. Thank you for your time. NiMH and NiCd batteries are simply produced of totally different material. By chemistry and physics.
That is why the charging structure influence differs. Battery charges are built accordingly with these in mind, by design they can be switched to NiCd or to NiMH options.
I have a brand new Li polymer 3. I bought it for my LED lights for my motorcycle helmet. My questions are: Can I use a mobile phone charger to charge it and that would be after I contact the battery to the LED device and then hook the cable in to the phone charger? How long should I charge it for the first time and how long should I keep charging it after as often as a regular usage? Your reply does not answer his question.
It is the charging current fixed known value , call it the charging current only. I was actually looking for a calculator that measures how many times a 20,mah power bank can be used to recharge a 2,mah phone battery and somehow I stumbled on this. This is also a very useful information! I guess I just learned more about batteries each day. Also, do the charging time calculator results have to be modified based on the number of cells in the battery pack being charged?
In my situation, the battery pack contains 15 1. My charger has an output of mA and no auto shutoff. Name or Subject required. Your Website. Rechargeable battery charging time vs.
