Is there any problem if I leave active batteries in the grip for extended periods? Will the grip run them down to "dead"? I heard this happens with some aftermarket grips.

You have to take out the battery to use the grip. The long thing sticking out of the grip goes in the camera. The grip comes with a holder that holds one or two batteries. And a holder that hold 6 AA batteries. I would go with two recharable batteries, since the AA do not last very long. The single battery last much longer than the AA's.

I've left the batteries in my grip and attached to my camera for extended periods (2-3 months) and the batteries don't appear to discharge any faster in the grip than they do out of the grip.

I don't know if the batteries will run down, but it's never a good idea to leave alkaline batteries installed in any device if it's not used regularly because of the possibility of leakage and corrosion.

the grip works great.leave the battery in your camera and a put the second battery of the same type in the grip.It does double your shooting .Tom

the grip comes with a insert that allows you to install two batteries in the grip.not sure what you mean by spare. if you are asking how many inserts come with the gripthen mine only came with one that allowed you to attach two batteries.

I used one for a year and a half in my D5100 before the camera stopped recognizing it as a compatible battery (likely the internal IC chip developed a fault). The warranty is three years so I contacted Blue Nook (the vendor). After a short phone conversation with a very nice gentleman he sent me not one, but FOUR replacement batteries at no cost to me! I have been using them in rotation for a couple of months now with no issues. I did not have to return the old battery, so in theory it should still be usable in a battery grip alongside a fully working battery (although I have not tried yet).

I have had no issues with the grip. I would remove it, clean the contacts on the bottom, and try again.

Just tried removing battery from the grip.(with priority to battery grip) and the camera shut off once I pulled the battery.If battery was set to priority to body and removed the battery grip the camera stayed on. Not sure if one can tell which battery the camera is using during recording (new user to camera) Haven't had the battery die on me yet with a normal day use.

I've used the battery grip in misty conditions, and some light rain conditions, making sure to dry both the camera and grip off as soon as possible. So far, no indications of malfunction or problems.

I have had mine for a year and so far so good. I am not a long distance hiker (20+ miles) but in the short hikes I have had no degrading of the grips.

I actually didn't use my Vita often. Maybe a couple days a month. That being said, its hard for me to tell if it was holding its charge, but it didn't seem like it did after the first 4 or 5 charges. I felt like the Vita had the charge and not the grips. I also had issues with getting it to charge at times and eventually the piece you plug the charger into came loose making that unusable. So its now just an overpriced grip that cannot be charged while playing. The grips themselves are great (if you don't need the trigger, the charge and battery part of it, not so much.

Thanks, not really an issue, grip works fine. I just wondered, since both batteries are always in play, why the shutter count for each battery and be different. A nit, really.

From what I've read online - the grips shut off if power runs low and they will flash and turn cold meaning you have to reset or cycle them off and back on - the condition is that the battery or alternator can't keep up on the high setting -- might be that the place they are wired in is not ample or that it just can't keep up and they fault -- so it won't run you down and leave you stranded -- my advice would be to run them on a lower setting and try to find the edge -- personally I put a switch on my headlight and just run my l.e.d. daytime lights when I can -- mine haven't done this yet but winters not here either!! hope this helps! singletrackjack on ADVrider!

Mine has worked perfectly as well since I bought it - no issues or problems at all. Not sure exactly what you mean by 'replacement pack' of batteries - I have only used the Nikon brand batteries in this grip, and like Chad K. posted - stay with the name brand for batteries. You won't be disappointed.

I haven't had any problems with Canon batteries getting stuck in Canon bodies or grips. I have had problems with third party batteries getting stuck in Canon bodies and third party batteries AND Canon batteries getting stuck in third party grips.

As in without charging for weeks then using it, or charge it up and start shooting, how long will it last? I will answer both. I have charged it and left it to sit for weeks then went shooting and was fine. NOT RECOMMENDED, but I have done it. How long will it last while shooting? This varies based on how trigger happy you are. I use it in my LMG and can play for 5-6 hours (shooting conservatively, AKA around 1500-2000 rounds during that time) and been fine. Good battery.

Similar to the other answer, the grip is fantastic and works well. The additional battery life you get will only depend on what battery you use, and the multiply it by two.
