The batteries both show 10 when fully charged with the Tenergy charger. A battery connected to three

Can you tell me where this is ?

China is the manufacturer of Tenergy batteries.

Do you think I can use this for applications that consume high current? What is the maximum number of mamps I can ?

NiMH cells do not operate at high draw. This is a normal NiMH In a short period of time, the battery can discharge at a continuous capacity of 100mA, with a maximum discharge capacity of 400mA.

The fenix paintball gun from spyder will be able to use these?

Is a 9 volt battery needed for a spyder fenix paintball gun? That's probably the case.

Update They get the job done
3/5

No, they never get it done even The third out of four of them is Having 2 of the green, red and white ones from Tenergy, one of them has already passed away, the other is still in good shape. These were necessary replacements and I had added another piece of equipment that needed a 9 volt, so I bought them. In addition to that, I have a ten year old energizer 9v that I still use today, but it doesn't provide the run time now. It is my hope that at least one of these four will still be going throughout The last three or four last roughly 3 to 4 minutes each A kitchen timer is used daily for four weeks in a commercial kitchen. The car was junk 3 out of 4 times. It can't even make it to its first week of I pulled the last one out of the pack and charged it up, and it said that it was fully charged when I went to the charger maintainer. I had it put into a timer, but did not make it past 6 minutes before the timer This is one item I will never buy.

NiMH Batteries 9V - Made by Great! These are the batteries I use in As a NiMH battery owner, I have plenty of them
5/5

This is mostly composed of AAs & AAs I mainly use AAAs, but I do have a few C, D, and 9V tubes. Firstly, if one is purchasing a NiMH rechargeable battery, it is imperative that the battery has a quality charger to ensure that the battery will perform at its best. The subject line of this message is There are a total of nine Tenergy 250 mAh batteries available Battery packs, these and the LSD from Tenergy A low level of self discharge This is the best 9V battery I have ever had. My four smoke detectors retain their charge for a long time. I switched to these for my seven smoke detectors at home. Using these up in smoke detectors will ensure that you always have spares on hand to replace "chirping" smoke detector batteries when they get low and set-up does not occur You can turn off the Low Battery chirp or alarm. I have been pleased with both of these Tenergy products as well as their LSDs, and I highly recommend both of them.

I like how it works
4/5

Overall, it has proven to be worth the money. It tends to hang when it is not charging and you have to jump it with a 9-volt to get it going again. But I like that all you have to do is just jump it at the right spot for a few seconds and you are In this case, it would be wise to turn off the device it is being used in or recharge the battery before it flatlines/is dead in order to avoid this problem.

I use it with my metal detector and it works perfectly
5/5

In order for my metal detector to run, I needed two of them. Choosing these over other options was driven by the fact that I didn't want to risk my lithium batteries getting bumped around or There is no need to recharge them between hunts, because they last for several hunts. To be on the safe side, I got a spare pair. As of now, it seems to work fine.

The batteries are of good quality and at a good price
5/5

Would you mind if I asked you what else you would like? There was a T for which these batteries were made. I have no problems with the unit, and they seem to last for quite a while. It does not last as long as some other types, but for the price, you can't beat it. It's already charged 75 times, and I have no more to charge They seem still to take matters into their own hands A new battery can hold a charge just as well as when it was To summarize, I am very pleased with them and would recommend them to anyone I paid $45 for them, plus an additional $10 for shipping The next time I need more, I won't hesitate to get it from you again. It's a good day for me.

Invest in something worthwhile and don't The only time I write reviews is when I'm reading them
3/5

Unfortunately, I have rarely been so disappointed by a product. I purchased these batteries about a year ago and thought they would be fantastic. My backup plan could be to use them as backup I am taking the smoke detector batteries out for replacement. It would stop the constant expenditure of money on replacing those parts every year. Initially all of them were charged and were working well, however, when they started to need to be recharged, disappointment began to It took no time for the first two to recharge. It was as if my smoke alarms were continually beeping. The batteries did not work in other toys that I tested. To date, only one of the batteries is working since I have been able to recharge only two of them. It was a total Despite my attempts to get in touch, I could only get an email response from the company They do not respond to defects issues emailed to them. My attempts to contact them were unsuccessful, and I was put on hold.

Get the best protection for your devices and save money today! Several of these would have been better purchased sooner, but I'm not complaining since I use my cheapo HF battery charger with These types of rechargeable batteries are known as dry type batteries, which means as opposed to alkaline batteries, they are not wet
5/5

They don't leak and destroy your devices, so I use them specifically in devices that may not get so much daily use, but are costly, such as my infrared thermometer, oscilliscope, and anything else that an alkaline battery might destroy.

When they arrive, they are dead
3/5

As soon as I got them, they were dead. As you might guess, I charged them for a long time and they did not come to life.
They are SO DEAD that infrared light cannot revive them.
I bought another bag of four and guess what happened? It was too late! They were dead! The dead have fallen! The dead have fallen! The dead have fallen! The dead have fallen! They came here DEAD, did I forget to mention that! A 0 out of 5 star rating.
