Past 2 times airsofting and battery holds up like a charm !!
ScotsWarrior45 –
It was for a CYMA G36c AEG BBsWouldn’t say it lasts any longer than the free batteries.Not sure if they are just faulty. Thank you
Stephen Foley –
These batteries are amazing for the price. I had a 30 dollar valken battery before these and right when i popped the keenstone in… i was shocked. These increased my fully auto fire by a little bit. Not like a lipo but i wasnt expecting increased rate of fire from a nimh. They last long and ive been shooting while its colder out too. Highy recommended

Bought this for my son’s Lancer Tactical AEG SR-16 elec. auto airsoft rifle. WOW, what a difference it made with automatic mode shooting. Before you could see about 7 inches of space, between each BB as it left the end of the barrel. Now there is about 1 inch of space between each BB as it leaves the barrel. It’s a constant stream of BBs as he hits his target. And the wires are twice the size of the other battery pack, which makes it a higher discharge rate. My son is very happy with this upgraded battery pack. Thanks for a excellent product at a good price, and fast shipping.

Initially got this for my airsoft lmg, soon found I needed a larger capacity battery (moved up to 5000mah) however I still tote this around in my pack just in case because it doesn’t take up much room and has just enough juice to get through around 2000-2500 rounds. Will buy another when I get a normal airsoft gat.

I have been playing airsoft since 2003. I own 8 AEG and 9 GBB in my personal collection. Been upgrading and repairing AEGs for since then.There will be those who say a battery is a battery. All batteries are sold with two ratings – nominal voltage output and storage capacity usually in milliamps (mAh). With all thing being equal, they all will do what the battery packs are designed to do. While this is true in terms of providing electricity, there is a difference in the amount of “push” that a battery can give. This battery from Keenstone tries to advertise their battery pack as having more “push” than other brands.I was running this battery pack in an upgraded Classic Army G36K running a M120 spring, which is good for 380-405 fps. Compared to the usual Intellect 9.6v 1600 mAh battery pack, I really could not tell much of a difference. Both brands are considered premium batteries so you could not go wrong with either. However the Keenstone is about 5-10% less expensive.During a 3 hour indoor CQB session, the Keenstone performed flawlessly. The rate of fire (ROF) seemed on par with the Intellect at about 14 shots per second in full auto.PROS: flexible wire leads, solid solder joints, clean shrink wrap, and insulation end caps.CONS: none at this time. Will update if run into problems.BOTTOMLINE: would I recommend this battery pack? Sure you can’t go wrong. Not sure if there is any warranty as most of these kinds of products don’t provide coverage since there are too many variables of potential abuse or misuse.

This battery comes packaged adequately and it looks exactly as pictured. Mine measured 10.4v according to my multimeter when I first unboxed it, so it’s nice to see it wasn’t very discharged.Plugging it in to my Cyma CM028a (tactical ak47) was easy since the plug is a direct fit. It fit perfectly in the stock and was easier to load than the original battery since it’s the nunchuck style. It fired well and is a nice small bump in power as compared to the original 8.4v that came with the gun. I’m fully satisfied with the performance, so when buying more I’d keep an eye on the price of this one and similar batteries to find the best deal.I was offered this battery for a discounted price in order to provide my opinion. I was under no obligation to provide a positive or negative review.

I ordered two airsoft guns after returning the old one from having a shooting problem. Both guns would shoot 10 rounds then drop in feet then not shoot at all. The bbs would just trickle out of the barrel. If I would halve know I wouldn’t have retuned my $250 airsoft guns so…. If your reading this please don’t buy it. Go on Evike.com and buy a battery that has great reviews on their

Very nice it made my gun shoot faster when I use it as a backup.Only reason as a backup is because more rpm = less accuracy… Though its not a big difference. Superb piece. Feel more of a kick and sounds great.Really good on single fire have enjoyed myself at sites.

Battery worked well in airsoft gun with light use. However, 6 months later my son’s gun became very jot and the sound of sizzling was coming from it. Pulled the battery and it was very hot and there was audible runaway reaction going on. Placed on concrete slab and allowed it to calm down. Battery is outside return window so I’m stuck. Would not buy this again and have removed the other one we bought from use.
Elaine Kimyi –
As good as any name brand. Hold charge ling time. Well packaged and overall good buy
Peter Birchenough –
I’m sure it’s a good battery, but will not fit into a KWA Ronin 6. It’s about 1/4” too long.
Dalton –
Good little nun-chuck style battery. I don’t really have anything else to say about this guy. Fits great into a crane stock. Pretty much on par functionality with what you would expect from any other airsoft battery with the same power ratings, nothing special, nothing missing. I usually buy Tenergy batteries and chargers, but I took a try on this one, and it hasn’t let me down. Good battery.

These batteries are amazing for the price. I had a 30 dollar valken battery before these and right when i popped the keenstone in… i was shocked. These increased my fully auto fire by a little bit. Not like a lipo but i wasnt expecting increased rate of fire from a nimh. They last long and ive been shooting while its colder out too. Highy recommended
Zackary –
Great for stock guns for a faster rate of fire, got a full day of play out of it, bit the battery will not run in any of my upgraded guns(high torque and high speed gears), but all in all great battery

After not charging this battery for a month and using it in an airsoft gun every day (20-30 minutes per day), it still performs just as if it were to be fully charged.

I have been playing airsoft since 2003. I own 8 AEG and 9 GBB in my personal collection. Been upgrading and repairing AEGs for since then.There will be those who say a battery is a battery. All batteries are sold with two ratings – nominal voltage output and storage capacity usually in milliamps (mAh). With all thing being equal, they all will do what the battery packs are designed to do. While this is true in terms of providing electricity, there is a difference in the amount of “push” that a battery can give. This battery from Keenstone tries to advertise their battery pack as having more “push” than other brands.I was running this battery pack in an upgraded Classic Army G36K running a M120 spring, which is good for 380-405 fps. Compared to the usual Intellect 9.6v 1600 mAh battery pack, I really could not tell much of a difference. Both brands are considered premium batteries so you could not go wrong with either. However the Keenstone is about 5-10% less expensive.During a 3 hour indoor CQB session, the Keenstone performed flawlessly. The rate of fire (ROF) seemed on par with the Intellect at about 14 shots per second in full auto.PROS: flexible wire leads, solid solder joints, clean shrink wrap, and insulation end caps.CONS: none at this time. Will update if run into problems.BOTTOMLINE: would I recommend this battery pack? Sure you can’t go wrong. Not sure if there is any warranty as most of these kinds of products don’t provide coverage since there are too many variables of potential abuse or misuse.

Bought this for my son’s Lancer Tactical AEG SR-16 elec. auto airsoft rifle. WOW, what a difference it made with automatic mode shooting. Before you could see about 7 inches of space, between each BB as it left the end of the barrel. Now there is about 1 inch of space between each BB as it leaves the barrel. It’s a constant stream of BBs as he hits his target. And the wires are twice the size of the other battery pack, which makes it a higher discharge rate. My son is very happy with this upgraded battery pack. Thanks for a excellent product at a good price, and fast shipping.

I’ve had no problems with my batteries. I purchased 3. They all charge/discharge properly. I recommend using a smart charger, discharging completely before charging and charging completely before using again. I don’t know if these batteries have a “memory ” or not, still a good habit for rechargeable batteries. I do know that over charging will ruin them. Either way, the batteries I received are quality batteries and work as they should. I will be purchasing at least 1 more.

So I bought this for my partners guns as hers was a cheaper make which eventually lost its mojo. After reading lots of reviews I thought I would use Keenstone as there have a good reputation and clear descriptions of what you are buying.Pros:- Long lasting battery- Fits most AEG’s, worked on my Barrett 50. G36, M4’s etc- Does not over heat (for me) when charging like some batteries have done in the past- Charges relatively quickly using smart chargersCons (very few):- Personally recommend using wire tape to wrap the cables as the plastic covering the wire will crack when bending over time- Prehaps a little more expensive than some other batteries (but…then you pay for good quality here)Highly recommend this to any airsofters looking for some extra powerful and battery life. 5 stars from me!

Initially got this for my airsoft lmg, soon found I needed a larger capacity battery (moved up to 5000mah) however I still tote this around in my pack just in case because it doesn’t take up much room and has just enough juice to get through around 2000-2500 rounds. Will buy another when I get a normal airsoft gat.

Great battery pac, I have used it and charged it a few times now and it works great, not as good as a LiPO but still good.
Matthew Heckman –
If you are still using NiMH this a great battery
Amazon Customer –
Only used it once and up to now I can’t fault it

I’ve had no problems with my batteries. I purchased 3. They all charge/discharge properly. I recommend using a smart charger, discharging completely before charging and charging completely before using again. I don’t know if these batteries have a “memory ” or not, still a good habit for rechargeable batteries. I do know that over charging will ruin them. Either way, the batteries I received are quality batteries and work as they should. I will be purchasing at least 1 more.

I use this battery in my airsoft g g m4. It comes with a mini tamiya connector. After fully charged, it lasted for days in my rifle. unbelievable but i strongly think it would last all day at an airsoft war great product. I bought this battery to upgrade my 8.4v 1200mah and so far it has done its job.

These batteries take a charge quick (full charge in less than two hours) and I got about 3 hours of use. No issues whatsoever.

My gun ( H&K 416 AEG ) came with a 8.4V 650 MaH battery. The battery gave poor trigger response and limited play time. Switching to the Keenstone gave me instant trigger response and way more play time!

Better than the Tenergy butterfly battery, and at less of a price tag!
Stephen Foley –
These batteries are amazing for the price. I had a 30 dollar valken battery before these and right when i popped the keenstone in… i was shocked. These increased my fully auto fire by a little bit. Not like a lipo but i wasnt expecting increased rate of fire from a nimh. They last long and ive been shooting while its colder out too. Highy recommended
Mattias –
Genial! Carga rápida, buena duración!

Awesome

Perfect replacement for Lancer M4 batteries. Wires are heavy duty, encased in the same type of plastic shrink wrap as the originals, same dimensions. Use a smart charger to keep them from heating up.

Bought this for my son’s Lancer Tactical AEG SR-16 elec. auto airsoft rifle. WOW, what a difference it made with automatic mode shooting. Before you could see about 7 inches of space, between each BB as it left the end of the barrel. Now there is about 1 inch of space between each BB as it leaves the barrel. It’s a constant stream of BBs as he hits his target. And the wires are twice the size of the other battery pack, which makes it a higher discharge rate. My son is very happy with this upgraded battery pack. Thanks for a excellent product at a good price, and fast shipping.

My previous battery went missing and I ordered this one as a replacement. So far it works just as well and it lasts quite a long time on a single charge. Definitely try this out.

Nice!

Bought this for my ak47 spetnaz and on a full charge last about 2 hours max. My 7.4 1000mah last longer than this. Although this may be cheaper by couple bucks I’d go for another brand like tenergy or valken

I have been playing airsoft since 2003. I own 8 AEG and 9 GBB in my personal collection. Been upgrading and repairing AEGs for since then.There will be those who say a battery is a battery. All batteries are sold with two ratings – nominal voltage output and storage capacity usually in milliamps (mAh). With all thing being equal, they all will do what the battery packs are designed to do. While this is true in terms of providing electricity, there is a difference in the amount of “push” that a battery can give. This battery from Keenstone tries to advertise their battery pack as having more “push” than other brands.I was running this battery pack in an upgraded Classic Army G36K running a M120 spring, which is good for 380-405 fps. Compared to the usual Intellect 9.6v 1600 mAh battery pack, I really could not tell much of a difference. Both brands are considered premium batteries so you could not go wrong with either. However the Keenstone is about 5-10% less expensive.During a 3 hour indoor CQB session, the Keenstone performed flawlessly. The rate of fire (ROF) seemed on par with the Intellect at about 14 shots per second in full auto.PROS: flexible wire leads, solid solder joints, clean shrink wrap, and insulation end caps.CONS: none at this time. Will update if run into problems.BOTTOMLINE: would I recommend this battery pack? Sure you can’t go wrong. Not sure if there is any warranty as most of these kinds of products don’t provide coverage since there are too many variables of potential abuse or misuse.

I honestly was expecting a battery like any other 9.6v battery you would get, but this battery really exceeded my expectations such as long battery life.for the price, it is a great battery.

Have used it about 6 hours strait without it dropping charge. Additionally, it holds its charge well between play sessions.When there was heavy rain and moister got in the batter compartment, there were no shorts in the wiring or any negative effects.
