I purchased this Canon DC10 DVD-camcorder about 6
years back. It could record 25 minutes with one battery
(BP-208) when it was new. Now even with a new fully
charged battery it records only about 7 to 10 minutes. The
recording is fantastic as it used to be. But it is eating
battery fast. What could be the reason?
For a solution I thought of purchasing a big size (fitting in
my bag) lithium-ion battery (say 12volt) and then convert
it to the required voltage using LM317 and then feed it to
the camcorder through the dc in (where the AC adapter
power supply goes). Will it work or I will just destroy the
camera?
Thanks for any suggestion.

Fake after market battery?
Your solution will work but the voltage drop across the linear regulator will contribute to wasted power. How many volts does the AC adaptor provide?

Thanks for your reply. I did not expect the battery to be fake as I purchased
from some good shop and Canon is printed on it, expensive too! Still it could be.
Just now checked the output of the adaptor with a multimeter: 8.2v, printed
8.4v 1.5A. Have some 2Ah 4.2v lithium-ion batteries, will series and
parallel them to get 8.4v and lots of Ah. Can I connect this directly to the
camcorder?
Thanks

The battery (BP-208) I purchased is from the following site.
Canon BP-208 Lithium-Ion Battery (850mAh) 0802B002 B&H Photo

What was the mAh rating of the original battery? B&H is reputable, but that does not rule out the possibility that somewhere in their supply chain counterfeit batteries were purchased. Also are you sure there isn't something wrong with the camera itself that is draining the battery?

I wouldn't. The battery you linked to is 7.4 V, not 8.4 V. The latter value is the charging voltage, not the nominal voltage.

But I plan to connect the (outside) 8.4v battery at the
point where the adaptor plug goes not where the
camcorder 7.4v battery is connected. Is it not OK then?

I'm not sure. Is it possible to run the camcorder on external power without the battery installed?
Yes, it runs on the external power (ac adaptor) without the battery installed.
That is why I thought of the solution in post 1.

I will check the manual, but do not remember reading
such a warning. It does suggest using the AC adaptor
to run the camcorder whenever possible. I have also seen
that the installed battery does not drain when the
camcorder is used with the AC adaptor. So I feel if I use it
with the external battery (as I plan) with the internal
battery installed then it will run for a longer time.
I will post the outcome.

Good news!
Just checked the manual. Explicitly written that one may or may not
keep the battery pack installed while using the camcorder with the
ac adaptor. And even if the battery is installed it will not be drained
at all. I will now go ahead and set up the external battery pack.
Thanks for the discussion...

Good to know.
One thing I just thought of... keep an eye on the charge of the external batteries. The camcorder will probably warn for "low power" only on the internal battery as that won't be necessary for an AC adaptor. Chances are you'll drain the external batteries below the "point of no return", and, as you might expect from that expression, then they'll die.

Thanks for the caution! I also thought about this issue. But found a solution to it. When the internal battery is installed and it is running on ac adaptor, disconnection of the ac adaptor (or voltage droping below 7.4v in the ac daptor) makes the
camcorder automatically start draining the internal battery. So I thought of
keeping a charged internal battery installed for such emergency. This will
protect both the external battery (from excessive discharge) as well as the continuation of the recording. The moment the battery indicator appears on the screen I will know that the external battery needs a charge.
Thanks again.

Wonder if there are electrolytic caps inside that are too old and are leaking current...
May be, but it is unlikely as the ac adaptor does not heat up excessively
when the camcorder is used using it. Also it is `made in japan' and only
6 years old. Not expecting capacitor will go bad so fast.

Finally my camcorder got a tail...
Some of the big batteries I had were discharged below the
critical level for I kept it connected with the charger for a
long time. So sourced some LG 3000mAh batteries and
got my 8.4v 16Ah. Everything fit inside the camcorder bag
well and working as if it is connected with the adaptor.
Only issue is that it has got a tail now...
