Impact battery problem. at DVinfo.net

Allan Black · March 10th, 2010, 11:30 PM

The Chinese Impact IMBP970 replacement battery I bought as backup for the A1 has developed a problem after about 30 charges.

Because it's 7600mAh I rarely run it right out on the cam so it always gets charged up from about 1/4 full. When the Canon charger light reads full .. installed on the cam this battery now reads about 2/3 full.

I think its developed a 'memory' and needs to be run flat a few times to restore its full charge. Haven't seen this for years it used to happen with the early Li-ion batts.

Anyone have this happen?

Cheers.

But Li-ion battery doesn't have memory effect problem. It could just be the problem of that particular battery you have.

Been there, done that.

Bought a Knock Off Canon battery a couple of years ago. Used maybe 30 times, always indicated fully charged after a night on the charger.

Put it in the camera, nothing, nada, squat.

Dismantled it to it's component parts. Guess what?

The cells WERE RECYCLED from other batteries and the chip that controls it was a Taiwan knock off of the real thing that wasn't worth the silicon that went into it.

Just not worth doing I'm afraid, there's a reason the real things are so much more expensive, tho' do have to say, not THAT expensive.

I learned about it too! There're some third party batteries are made with "recycle" battery. That's why they are even so much cheaper that can be found on ebay.

We have BP-970G and BP-950G battery for sale. they are generic brand made with high quality cell. I myself are using them for my XH-A1 and XH-A1s. Those that I start using 3 years ago are still holding charge well.

My Impact battery was sold to me by BnH in New York .. it's not listed there anymore and mine is at least 18months old.

Cheers.

There is obviously a discrepency between the Canon charger, the battery and the camera.

Li - ion's don't develope memory, so it seems likely either the battery is partially toast or the charger isn't seeing what it thinks it should.

Either way, it's a moot point, if a cell has failed (possible) then it's well out of warranty, so it's either use it as is or replace it.

PS: You could always try to find a company like this is Aus, can't believe there wouldn't be one. I had a couple of battery drill packs re -done by these guys and they ARE HOT. Had 'em over a year and still haven't needed to recharge them, but then, I don't use 'em every week.

Thanks for that tip Chris. After running that Impact down and recharging it, it's back up to full charge this morning. Still a worry though.

Cheers.

Depends, I have a Lenmar clone at 1/4th of original price, it doesn't run as long as my original canon battery but has had many recharges untill now. I also have a Sony Lenmar clone for my hvr-dr60 and that one was 8 times more cheaper then the original one and after a year it still works as in the beginning. (knock on wood :) )
