Better Battery Technology
Over the years, battery technology has changed significantly in both power and size. Original, rechargeable cells were the size of tractor trailers and as the technology filtered down the first rechargeable batteries for consumer use were small, alkaline cells for cameras and toys. Finally, as new materials were brought into production rechargeable battery got larger, more powerful and took less time in charging. Perhaps the greatest modification to battery technology, and one the has the biggest impact today and on the trimmers is lithium/Ion technology.
Essentially, a lithium/ion battery allows for the electrons to travel both ways from the negative to the positive during use and from positive to negative during charging. All this without requiring an change in electrolyte.
Lithium/ion batteries require extensive testing due to the flammable electrolyte and thus all batteries are sealed and should never be opened under any circumstance. Furthermore, during charging if the batter shows excessive heat unplug the battery and do not use in your trimmer.
