I was wondering if someone can offer me some advise...
About a month or two ago I bought two 9.6V 1400mAh D-BAL style batteries from ANGS in Meguro. I had gotten a few boxes with a used purchase, but that batteries that came with it at the time didn't work. I didn't want the two boxes to go to waste so I bought two fresh batteries.
The battery cells themselves are intellect batteries.
I have charged each of them with the same charger I use for my other batteries, but they just don't seem to hold a charge. When I fire in semi-auto they are really slow to turn over the motor. It takes almost a second to fire a round.
Full auto only gets about 4 or 5 shots off (slowly) and the battery dies.
Both of them are showing similar behaviour.
Does anyone know what might be causing this? It is very frustrating...
Here are links to said battery and my charger...

Thanks for your help.
How long was your 1st charge after purchase? Have you tried deep cycling the batteries?
They initially seemed charged, so I used them, but they died quickly, and never seemed to charge properly after that.
What is deep cycling?
There is a possibility to have discharged electricity when it was in the shop.
I had heard that the batteries need to charge when it was in the shop.
Did you charge it by 1A?
Here's a little from wiki, in case you hadn't checked yet:

Do the batteries look particularly old? The problem with NiMHs in general is the shelf life is not quite as good as other types. If left for too long, the self discharge can cause the batteries charge capacity to decay over time, as the article states. Temperature is also a factor. This is why sometimes you see batteries sold in stores going on sale, since after about 2 years the maximum charges they can take goes down. Is there any indication of the date of manufacture on the box for the batteries?
If you can, also try someone else's charger. It might make the difference,
Thanks for the tips guys,
I bought the batteries on sale, but there was no indication that this was because they were old.
Bought them brand new about 6 weeks ago, so they haven't been over used.
There was a charge in them when I brought them home, and didn't charge them until i had tried them out.
My charger has a 1A, 2A, and 4A setting. I used 1A when I charged it.
My charger is a "peak charger" so I wonder if I need to get a charger that properly drains the battery before recharging it?
They have also been sitting out open in a cold first floor. I wonder if teh warmer weather will make a difference?
Thanks again all.
Cold is good for batteries, it slows down the self-deterioration of the battery and avoid having to charge them every 2 month without even using them. I keep all my batteries in my fridge, but always wait a little for them to warm up before charging/using though, thermal shock is not a good thing.
dStole, when I'm back from Oz, may I take the batteries off your hands to deepcycle, test? See if I can reset it or if not, tell ya to dunk it. I'll be in Oz between 13->19th so best after 19th.
As for freezing, easy find.

"Putting batteries in the freezer or refrigerator doesn't necessarily prolong their life??"
Alkaline batteries stored at "room temperature" self discharge at a rate of less than two percent per year. So normally refrigerating or freezing them will only help maintain their charge by a tiny amount. Hardly worth the effort of chilling them. However, if alkaline batteries are stored at higher temperatures they will start to lose capacity much quicker. At 85 degrees F they only lose about 5% per year, but at 100 degrees they lose 25% per year. So if you live in a very hot climate or are storing your batteries in a very hot location, it may be worthwhile for you to store your alkaline batteries in a refrigerator instead.
NiMH and NiCd batteries self discharge at a MUCH faster rate than alkaline batteries. In fact, at "room temperature" (about 70 degrees F) NiMH and NiCD batteries will self discharge a few percent PER DAY. Storing them at lower temperatures will slow their self discharge rate dramatically. NiMH batteries stored at freezing will retain over 90% of their charge for full month. So it might make sense to store them in a freezer. If you do, it's best to bring them back to room temperature before using them. Even if you don't freeze your NiMH batteries after charging them, you should store them in a cool place to minimize their self discharge.
Yup, cool place for sure, especially with Japanese summer around the corner.
As per literally freezing the batteries, I feel a little reluctant to do so. I'm not familiar with the actual freezing temperature for the electrolytes and components inside the battery, but minus something feels a little too much, and I'm actually afraid of damaging the battery by doing so. Fridge is a good compromise for me
I was asking to AEG Shop about the Angus' D-BAL box battery.
Shop person said me the following,
"D-BAL Box batteries seems to have the low-quality cells and leftover.
Though it is only a personal opinion to the last."
I felt that the Ni-MH's performance fall down when it continue to use for about one year.
Therefore we will exchanged to Li-Po battery instead of Ni-MH for all our guns.
Watchout for Li-Po though, they do break/get very hot. Already saw several in game doing so, just even the last Seal game I had there was a Lipo that burst.
I personally prefer Ni-Mh, since even though their lifetime is limited, at least there is no bad surprise, just need to buy new ones. Li-Po are good, but I don't want to be constantly wondering "when it will give up".
Your opinion is also important.
I heard the accident of Li-Po.
There seem to be a lot of accidents of it in the mistake of the charge method.
I am using it while fearing it
