Patented 3 stage charging system maximises the life of batteries extending its potential life by equalising the charge in each of the batteries cells.
As both ports function independantly an 18 volt battery can be charged at the same time as a 7.2 volt battery.Features: Charges two batteries in 1 hour or less, minimizing down time.
Charges all DEWALT 7.2V - 18V batteries (except Univolt batteries) so users need only one charger for multiple cordless products.
Battery thermal protection system prevents charging batteries that are too hot or too cold which would cause damage to the battery and a loss of run-time.
Diagnostics with LED indicator are 5 indicators to communicate battery charge status: charged, charging, power line problem, replace pack, and battery too hot or too cold.
