Can Nicd rechargeable batteries be replaced with Nimh rechargeable batteries for solar lights?
The two types of rechargeable batteries are similar in performance and many characteristics are the same. Importantly, they both deliver a voltage of 1.2V so the devices they drive will respond in the same way. The two technologies differ in the way that they should be charged. This is only a concern for fast chargers. Nimh batteries can be fully charged in about one hour but it is is important that the charger monitors the battery and shuts off the charge at the right time to avoid damage to the battery. NiCd batteries have a different charging characteristic so charging either battery in a fast charger designed for the other type is likely to lead to damage or reduced performance. Solar lights use solar panels to charge batteries over a 12 hour period or more. The charging current is low enough to avoid the risks of damage to a Nimh battery so it is very likely that they can be used. There should be no risk of damage but the only way to see if the batteries work in a light fitting is to try it and see if it works. If it doesn't, it's time to switch back to NiCd batteries.
How many cells does a 6 volt battery have?
It depends on what the 6 cells are, but the battery voltage is just 6 times the cell voltage. In a car battery (lead-acid cells) - 12V In a dry-battery (zinc-carbon cells) - 9V
