My dewalt 18v battery charger actually charges 46 volts and 2 amps, why?
Does this set up the NIcad batteries for Early Failure? Shouldnt it be 18 volts and 2 amps instead?
the 2 amps is the continuous amperage from the bottom label.
The open circuit voltage might be 46 Volts ... but it wont be when the batteries are hooked up. If the charger could maintain 46V while attached to the batteries, the current would go way up and batteries would be ruined almost instantly.
Most chargers have some intelligence built in (as do many batteries) include monitoring of voltage, current and temperature.
I just finished a reverse engineering job for batteries and charger for a major tool company ... the batteries had microcontrollers with A/D capability and temperature sensors on board. The chargers were quite suffisticated as well including pulsed charging schemes and monitoring/balancing of individual cell voltages.
Edit: To be fair, the tools I was investigating were at the higher end. It's true that there are a lot of 'stupid' chargers out there than can really harm/shorten the battery life.
