I try to avoid having to use it if possible, but I do have a spare Impact battery (and another cheap generic, which I pray I never have to resort to) that I've used with the A1. And yes, it did get stuck.
I paniced at first, but the solution was pretty simple. Just hold down the release button until the entire battery is out. If you just press it and expect the battery to release, it will get stuck. If you try to pry it out, you WILL be sorry. Again, just hold down the release button until it's all of the way out and you'll be fine... |

It's not the fuel guage, but the battery chemistry.
Nickel cadmium batteries can develop a "memory" effect if they are repeatedly partially discharged. Deep cycle charging them periodically helps to prevent this. Lithium ion and nickel metal hydride batteries are not subject to the memory effect. On the other hand, they cost more to purchase and don't last as many charge cycles as a properly cared for nicad, so there's your tradeoff. Li-Ion batteries are also said to suffer from a gradual decrease in total capacity over time, about 10% per year, irrespective of usage. However, I only have this from one source and haven't confirmed it. |
Li ion has a operating life of 2 to 4 yrs. You do see a depreciation of capacity over that time, but that is the same with any chemistry of battery.
|
fwiw, anton bauer warrantees their dionic bricks (li-ion) for less time than their nimh and nicad lineup. haven't used dionics, but user reports seem to indicate the battery will eventually fail after a couple of years. their big advantage, however, is their light weight. on the other hand, i know people who have been using the same propac bricks (nicad) for a decade.
soap box note: nicad batteries are the worst for the environment, and proper disposal of all batteries should be observed. radio shack, for one, will take old batteries. and rathbone, and other companies, will recell/recycle them. getting back to the xha1, if anyone is interested in using an anton bauer power solution with this camera, or any other camera that uses canon bp-style batteries, switronix makes a cable with a 7.2v canon battery mount on one end and a 12v powertap connector on the other. http://www.bhphotovideo.com/bnh/cont...ughType=search you just need to cut off a little plastic nub on the connector housing with an x-acto knife or razor for it to fit on any standard ab gold plate. cable lengths are available in 20" and 48". i'm currently running the xha1, marshall lcd, ab light, and, occassionally, the redrock m2 off a single ab brick. |

[Quite]As I understand, this does not change the capacity of the battery but rather the reported capacity, such that you don't experience batteries run out prematurely[/Quote]
I've seen this feature in documentation for some NiMH-powered devices. The remaining run time display system (e.g., on a laptop computer) required an occasional deep discharge cycle with the installed battery to recalibrate the displayed remaining time system to the condition of that a batttery. |
Battery Question
The standard BP-950G that comes with the A1/G1 has 5 metal contacts on the end.
I bought my A1 with an optional battery and upon further inspection the battery says it replaces the BP-945. It's a 6000mah battery. The concern I have is that the battery has only two contacts vs. 5 on the battery that came with the camera. The three in the middle labeled T,B and G on the standard battery are missing but the two longer contacts on the ends are there. The camera works fine with the battery but I was wondering what the three middle contacts do... I only paid $75.00 for the 6000mah battery so this seems to be a cheap alternative. Just making sure it's acceptable. Thanks, -Jonathan Gentry |
I found a few posts about the difference in the number of contacts on these batteries (2 vs. 5) but no answer as to what the middle three contacts do. It looks like others are using the 2 contact batteries with no problems so I won't worry too much.
If anyone finds out what the three contacts in the middle do let me know. Thanks! -Jonathan |
Battery Discharging When Off???
Hey guys... Usually I remove the battery pack from the camera when I stow it away out of use, but this past time I left the battery in the camera for a couple days without use.
Yesterday when I took the camera out of the bag, I noticed the battery was completely dead when I tried to turn the camera on. And this is the big 3.5+ hr BP-950 Battery pack. The odd thing is, the battery had a near full charge when I stowed it away. I did not leave the camera on when it was stowed away. Does anyone know if this is normal... and if not, what could have caused this? It seems odd that the battery discharged itself like that. Thanks for any thoughts. |
I left mine in for several days and it didn't seem to discharge very much at all, if any. Might be a problem there.
|
Mine doesn't discharge noticeably, so I don't think it is normal.
Richard |
Left it in for a couple of weeks with no noticeable discharge - and that's on the smaller one that comes with it.
|
Hi,
As a digital still camera tech, this fault is quite common, with regards to faulty power pcb..Dark current (power off battery drain) is way beyond manufacturers specs...So this would not be normal for a camera, in terms of correct operation. This MAY be the case with your camera...Dont mean to scare you. |
Might depend in part on the charge state of the internal back-up battery. If it is discharged it will draw power from the removeable battery to fully charge it, but that should be the main draw when the camcorder is otherwise turned off.

Deke,
What we do ( NOT SUGGESTING TO DO THIS! ) to diagnose the fault, is hook it up to a powersupply with amp meter (directly to batt contacts)..and check that its drawing a particular amount of current, something like 300 uAmps when turned OFF...Cameras usually go off the scale when faulty, drain batts very quickly. IF, it is the case with your camera, meaning you can reproduce the fault, I would definatly send it in to be checked....First off I would try another battery...It could be the battery/Charger. I just want to make it clear..The above comments relate to digital STILL cameras...and may not be relavant to your camera. |
Funny. A Lenmar LIC941 I bought in 2001 fits, but some I bought in 2004/2005 stick and need the gaffer tape trick to pull them out. Bummer.
The 2001 battery is questionable, and headed fopr the recycle bin, as are some smaller batteries dating to 1999. |
I was reading up the other day on the LOCK / STANDBY feature. I was wondering if when in LOCK (the switch that holds the settings you were at but powers down the camera) if technically the camera is still 'on' and drawing battery life. I used the lever yesterday and later wondered if I'd left it on LOCK and if it was drawing juice while packed away.
I couldn't find battery info in the manual in reference to the lever. Trish |
First thing to do!
Before you get into sending for repair and fancy testing, try this to make sure the battery has not gone bad.
1. Fully charge the battery that was in it and let it sit for a good period, off of the camera and test it again. 2. Try a different battery in the camcorder, and see if the problem is still there. It may be that you just have a battery going or gone bad. Mike |
How many batteries?
Hey all,
I'm going to be using the XH-A1 at a wedding for the first time next weekend and I'm a bit concerned about something. I have the stock Canon battery and the Impact BP-970. I'm wondering if these two batteries, fully charged, will be enough to get through a full day of shooting. The wedding is outdoors and I doubt I will be able to plug the camera up or recharge either battery and I want to be reasonably sure that these two batteries will be enough. Any and all opinions will be appreciated :) Thanks, Doug Chambers |
That's about ten hours of endurance, but I would add a third batt just to be on the safe side.
|
Don't worry, the batteries really do last for ages. I did a wedding 2 weeks ago and only switched from the stock supplied battery at the start of the evening reception. I reckon the larger BP945 would have seen me through the whole day easy.
|
If shooting for money, you can never have too many blank tapes or too many fresh charged batteries with you - you can only have too few. No one knows or cares if you have more than you needed, but the client gets mighty upset if you have one less battery or tape than you needed.
I would say plan on at least one good charged battery (e.g.., BP950) for each 1 hour tape you plan to shoot. You will not need that many if you use StandBy/Lock during long pauses in action at a typical wedding. Adjust this ratio as you gain expereince with your gear and shooting techinque. Keep in mind, the more you shoot at a wedding, the more you have to sift through as you edit and the longer it takes to produce the end product. |
Thanks for the advice. I just went ahead and ordered another BP-970. It hurt the wallet a little bit, but it will be sure to save me tons of worry. $130 is a decent price for peace of mind, isn't it?

Anton Bauer ElipZ 10k Under Camera Mounted Battery...?
Does anyone have this battery? I`m confused about its usage. It comes with the A1 package, but the description is it works specifically with the G1/2 Xl 2. If you mount it under the camera can you not use a tripod? Or can a quick release attach to the battery, but won`t that mess with balancing the camera since the weight will all be in one little point under the cam? Also once the battery is under the camera...how does the power get into the camera?
http://www.bhphotovideo.com/bnh/cont...=437763&is=REG |
The battery has it's own tripod hole, so you can still use a tripod. The power gets to the camera by way of a dummy battery. In the picture from the link, it is the bottom right thing, beside the charger. As long as the A1 has the same battery as the GL/XL series, this setup should work.

My guess is that a 970 battery is going to be more than enough and this one is a little overkill. |
Actually, if you look a little closer at the battery door, you will see there is a slot for snaking a cable out. Also works with the AC adapter.
|
My bad - thanks for the heads up.
Still don't like the door thing though |
Considering the price of that battery, I would invest in a few 970's.
Exchanging those batteries should not be a problem because you also have to exchange tapes. Except when you use a harddrive solution ofcourse. My 950 battery runs for about 4-5 hours. More than enough for me. I think a 970 will run for 6-7 hours. So with three of those you could almost run 24 hours. Next to that: with two or three you also can reload the empty one in between. |
I agree. With the battery that comes with the camera and a second 970, you can pretty much shoot all day. Buy a third battery and you're cool for about anything. That big Anton Bauer battery is probably about as heavy as the camera. I don't see any need for it.

elipz with XL-1
I just got the Anton Bauer system for my XL-1. I had a belt mounted Bescor battery that gave decent battery life (maybe 3-4 hours) but it weighed a tonne.
Anyway, I have been using the elipz for the past three days and have been very pleased with it. Now admittedly the XL-1 is a heavier and possibly more power hungry beast than the XH-A1, but the battery pack itself is very lightweight and I didn't feel that it added any weight to the overall rig. I also really like the fact that I just don't need to worry about running out of juice. As is the case with all external batteries I've used, you lose the battery meter function in the camera and there's no real level indicator on the battery pack itself other than a "have charge" light - I would prefer a Mac-style battery meter on the battery. The other advantage is being able to run the elipz on-camera light at the same time with no additional battery. The biggest issue I found is that the system uses a stacking power connector and the connector for the light is quite lose. Unfortunately, this has to go in before the camera's dummy battery connector and I found myself unplugging everything inadvertently on a couple of occasions. This is nothing that can't be solved by velcro tape or gaffer tape, but it is in my opinion a design flaw. Power connectors should really be locking. |
Silly Battery question
I am about to purchase an XH A1 as I have sold one of my XL2 cams, I just wondered if someone could tell me if my XL2 batteries will work with the XH A1. What model comes with the A1? Are they interchangeable with the XL2? Thanks.J
|
The A1 runs on a BP-930G/950G/970G, as does (I believe) the XL2.
|
I kept my 2 spare batteries when I sold off my XL2, and am using them with the A1. And the charger that comes with the A1 is the same part number as the XL2 charger.
