Well i charge mine for 2 hours. For me the battery was in an airsoft gun magazine when i was younger. I remember that i over charged it and it broke so i wouldnt go over 2 hours. hope that helps.
NiMh is usually considered the most direct replacement of NiCd.
Very carefully
NIHM stands for nickel metal hydride battery. The NIHM batteries are similar to other types of rechargeable batteries like the more common nickel-cadmium NiCd types but with much more charge capacity.
The state of charge (SoC) of a nickel-cadmium (NiCd) battery is typically determined by measuring its open-circuit voltage (OCV) after a resting period, as the voltage correlates with the charge level. Additionally, a discharge curve can be used, where the voltage is monitored during discharge to estimate the remaining capacity. Another method involves using a specific gravity meter to measure the electrolyte density, but this is less common. Overall, OCV measurements are the most practical approach for determining SoC in NiCd batteries.
Can be just about anything, from a small button battery for a small LED, to NiCd to Li-Po.
yesYou can use a NiMH battery in just about any application you would use a normal alkaline battery. However, NiMH batteries do not perform well in low energy applications - they are designed for use in high energy devices like digital cameras. For things like clocks, standard alkaline batteries are better suited.In my personal experience, the NiMH and NiCd batteries did not perform as well in my wireless LASER mouse. Alkaline batteries performed a whole lot better. The problem is that NiMH and NiCd have relatively high "self discharge" rates; that is, while they are not in use, they will loose their charge over a fairly short time as opposed to alkaline batteries which loose their charge at a much smaller rate and over a much, much longer period. Also of consideration is the fact that rechargeables (NiMH & NiCd) produce 1.2v at full charge (NiMH can achieve 1.4v, but for very short time) whereas alkaline batteries are 1.5v. This 0.3v can be a problem with some electronic devices. 9V rechargeables only deliver 7.2v.
AA rechargeable batteries typically take about 4 to 8 hours to fully charge, depending on the charger and battery capacity. It's important to use a charger designed for the specific type of rechargeable AA batteries, such as NiMH or NiCd. Always refer to the manufacturer's guidelines for optimal charging times to ensure safety and battery longevity. Avoid overcharging, as it can reduce battery life.
NiCd, Lithium, Lood, NiMH, Li-ion, Alkaline. I can't tell you which types are appropriate for your medical device(s), anyway! (NiCd and Lithium battery types must be disposed off properly).

No, but refrigerating NiMh/NiCd batteries will increase their shelf life. Never freeze batteries.
A NiCad charger has different sensor values than NiMh. I would find a charger that has a switch to select either, or specifically a Nickel Metal Hydride battery charger to prevent damaging and shortening the life of your batteries.
Yes, as long as you use an NiCd charger, but you really shouldn't. NiMh has twice the capacity of NiCd and it is less expensive. NiMh also contains no toxic materials so it is better for the environment.
