What is the Best Nimh Batteries Cs?
Overnight Charging The cheapest way to charge a nickel metal hydride battery is to charge at C/10 or below (10% of the rated capacity per hour). So a 100 mAH battery would be charged at 10 mA for 15 hours. This method does not require an end-of-charge sensor and ensures a full charge.
Is it really necessary to fully drain the Ni-MH batteries before recharging them? If you have a charger that detects the end of the charge from negative delta-V or temperature, it’s actually beneficial not not drain the batteries fully. The secret? Toyota hybrid batteries operate only in their middle state of charge region. For such slow timed chargers, the optimal way to charge is to first completely drain the battery and only then recharge. For lithium ion, it is impossible to do timed slow charge, so lithium ion batteries do not have the problem of some chargers being very poor. About the memory effect: the memory effect in Ni-Cad batteries is only observed if the battery is cycle all the time to exactly the same state of charge, day after day after day. When battery users saw their Ni-Cad batteries that were not fully discharged prior to recharging have an unacceptable cycle life, they attributed this to the memory effect.
Do you need to discharge rechargeable batteries? It is significantly better for NimH batteries NOT to discharge them fully before recharging them. NimH life can be enhanced substantially by never discharging them fully on any occasion. If you stop charging when the battery temperature first starts to increase rapidly they will thank you for it longer term.
How do you keep a battery charged when not in use? If you find any of these cars start easily (the starter spins quickly), battery status is likely quite good, and a short drive or idling for 10 to 15 minutes may be adequate to keep the battery full, if done once every two weeks. If slower cranking is noted, a half hour drive once a week should do the trick.
Can you charge and use a battery at the same time? 3 Answers. While it is true that you can’t actually charge and discharge a battery simultaneously, it is quite common to have a charging source, a battery, and a load, all connected in parallel so it looks like you are charging and discharging simultaneously.

Can NiMH be fully discharged?
(1.5 volts – fully charged, 1.25 volts – 50% charged, 1.0 volts – almost fully discharged). But a NiMH (or NiCd) battery stays at about 1.2 volts until it is nearly completely discharged. This makes it almost impossible to know the amount of capacity left based on its voltage alone.

about 1% per day
How long can a car battery hold a charge when not in use?
If your car battery was manufactured a month ago and has never been previously installed, it should be enough to put it on a slow charge for 22-24 hours. After charging, put it in a dry and warm place with low humidity, for example, in a closet. Repeat the charging process every 2 months until you plan to use it again.

4 amps
Can you overcharge NiMH batteries?
A NiMH in a NiCd charger would overheat, but a NiCd in a NiMH charger functions well. Modern chargers accommodate both battery systems. It is difficult, if not impossible, to slow charge a NiMH battery. Harmful overcharge can occur when charging partially or fully charged batteries, even if the battery remains cold.
What voltage should I charge a NiMH battery?
1.6 V
Does a car battery lose charge when not in use?
A car should be able to sit parked for at least a month without the battery dying, unless it’s a higher-end car with plenty of power-hungry gadgets and computers, experts say. That reaction keeps happening, but more slowly, when the battery isn’t being used. That’s why batteries lose their charges as they sit.
