Yes, the mAh rating will give you longer run times between recharges. NiMH battery can be charged and discharged a few hundred times, but whether that means 100 times or 800 times has a lot to do with how it is treated.Ĭan I use a higher rated mAh battery (i.e. The number of times a battery can be recharged depends on how the battery is used and how it is charged. How many times can a NiMH battery be recharged? The 2000mAh means it should give 2A for an hour although as discussed in ' Capacity' this is very rarely so. So if a battery with a 2000 mAh rating will have twice the capacity of a 1000 mAh rating. This is a rating of energy storage capacity mAh = “milli- ampere hours”. In the new generation of NiMh batteries this effect is vastly reduced and so they can be recharged at anytime during usage cycle although a complete discharge occasionally may be advantageous. This is when a battery must be fully drained before recharge or their capacity is reduced. Older generation and batteries (NiCad) were subject to a memory effect. The material is Nickel Metal Hydride (NiMH) which has many advantages over other battery construction materials. Here are some answers to common questions The cheaper chargers rely on a resistor to limit the current (as the battery voltage rises the charging current falls but never goes to zero) this can lead to overcharging if left on.Īnd because you have no indication of when the battery is fully charged it is often underchargedīoth over and under charging affect battery life. I personally think the best way to look after your batteries is to invest in a good autoĬharger. The ones used in model yachting are mainly NiMh and Life because of the high cell voltage (2 cells =7.4v) is not compatible with all receivers but I have covered Lipo as well. There are several types of battery used in R/C models.
