A 300mAh battery can technically replace a 400mAh battery in some applications, but it will have a reduced runtime, as it stores less energy. This means devices powered by the 300mAh battery may not operate as long before needing a recharge. Additionally, if the device requires a certain voltage or current that the 300mAh battery can't provide, it may not function properly. It's important to check the device's specifications and requirements before making such a substitution.
Yes, that should cause no problem because the voltage is the same (a small discrepancy should usually be tolerable). The larger "mAh" rating simply tells you that the battery will last longer, for any given load.
the 300maAH is volt rechargeable battery is the highest true capacity battery
It is not recommended to use a higher capacity battery (600mAh) instead of the original one (400mAh) in a solar light without knowing the specifics of the light's design. Using a higher capacity battery could potentially damage the light's circuitry or affect its performance. It is safer to use a battery with the same or lower capacity as recommended by the manufacturer.
If you need a battery then there is nothing that can replace it.
