Was pricing the EOS 1ds NC-E2 charger for the NP-E3
NIMH battery pack. I was flabberhammered by the price
those chargers command. For some reason, a used one
can sell for up to 250. Was wondering if anyone knew
anything about the charger. Is it special in some way.
I noticed the output is a rectified 14.5 volts. Since
anyone with a transformer a couple of caps and a few
diodes and resistors can producr a power supply that
can prouce 14.5 volts, I was wondering if there's any
reason i couldn't just whip one up and hang the dead
battery on it for a couple of hours. Also, are generic
chargers available?
Javier,
There is more to a charger than the output voltage.
Most modern quality chargers have electronic circuitry that can tell
when a battery is at full charge. Then there is the specific battery
application. usually chargers sold by, say Canon for example, are
designed electrically and physically for specific physical styles of
battery packs. This makes the price go up since the production
quantities are relatively small.
There are generic chargers available that safely charge batteries but
because they are generic they do not accept the physical battery and
have a universal type of connection to the battery terminals. there are
also some that have a standard electronic "package" and adapters that
fit and physically accept a specific battery.
For my ham radio handheld equipment I use a "Master Charger" system that
came with a drop in 'cup' the I just drop my hand held into and the
connections are made. If I change hand held radios I can buy a new
'cup' to fit the new radio if needed.
One of the companies that make chargers is MAHA. I have two of their
chargers that charge two or four AA or AAA NiCd or NiMH cells and one
of their universals with the adapter for my hand held ham radio.
I am not necessarily recommending MAHA but letting you know that they
are out there. There are other brands.
