Unlike a lead-acid battery which can take large variations in amperage and voltage while charging, the NiCad batteries require steady amperage and only very slight variations in voltage. The charge rate for a NiCad is right between 1.2 V …

How Does Lead-Acid Batteries Work?

Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.
