Ni-MH 6V Battery Pack, 2400mAh Rechargeable AA Battery with SM 2P Plug and USB Charger Cable for Amphibious RC Car, Outdoor Solar Light, Electric Tools, Q60 Q61 1/16 Military RC Truck SL01

The battery packs in my solar flood lights were failing. They wouldn't hold charge. These were exact replacements. Easy to install. My solar lights are now back to providing the needed service in my yard.

This was a replacement for my solar powered security motion sensor light from Harbor Freight, which had a bad battery. The battery fit perfect and works perfect and was very inexpensive and fixed the problem with the light working perfectly

Yup, it's a 40 yr old "Pocket Computer" printer... that I decided to give it life. These batteries were the "defibrillator" so to speak. The TRS-80 pocket printer uses 5 x NiCad batteries in a 3 long + 2 long configuration. By carefully removing the shrink wrap on this pack I then use a tiny bladed hobby knife to separate the batteries length wise. I did NOT have to break or undo any of the tabs on the batteries. So I ended up with a 5 long set of batteries. Folded it 3x2 like the original, then used shrink wrap to hold them all in place. I was very careful with the heat on this so as to not get the batteries hot!!!.I then cut off the connector and soldered the wires to the original wires, again using shrink wrap to isolate and insulate. The rebuilt pack fitted exactly in the case, just like the original packNow I purchased this 5 x 1.2v NiMh as they have a much higher capacity and they were replacing a 5 x 1.2v NiCad battery pack. That means the charger is a not as smart as modern chargers that limit current when charger NiMh. However, as long as you do NOT leave on charge forever, and remove from charging if it feels unduly warm when charging, you should be just fine.Radio Shack manual says that the NiCads should be charged for 15 hours!!!... that's a slow trickle charge. So I charged the NiMh for about 12 hours and it worked a charm. Just never leave NiMh batteries permanently connected to a powered NiCad trickle charger as that will ultimately damage them. NiCad's were designed to handle that.NiMh are much higher current capacity and will power your device much longer than NiCad, they also don't suffer from battery memory as much as NiCad do. So overall, you can actually replace any NiCad with a NiMh (as long as you are careful about what charger you use as noted previously).While everything today is Lithium, be aware you cannot normally replace NiCad nor NiMh with Lithium for various reasons. The voltages are one thing, plus the charging is completely different. An experienced engineer could do it but it is more than just switching battery packs so don't try it unless you know what you're doing. Incorrectly charging Lithium can cause them to melt and eventually explode!!!While my usage of this battery pack is for an archaic device to give it new life, I will say that the pack was excellent value for money. Just took some careful cutting, re-shrink wrapping and soldering to inject new life into an old device. Very happy with my purchase.

The battery itself functions as expected and charges well. However, the included USB charger poses a serious safety risk. During use, rather than properly shutting down after the battery reached full charge, the charger began emitting a burning smell. It took us some time to locate the source, only to discover that the charger was melting and starting to actively burning.A USB charger should never reach a point where it overheats, melts, or causes a fire hazard. Properly designed chargers include safeguards to monitor charging conditions, prevent overcharging, and shut down in the event of an issue. This charger failed to meet those basic safety standards, making it dangerously unreliable.While the battery is fine, I cannot recommend this product as a whole due to the severe design flaw in the charger. Please use caution if you choose to purchase.

Plugged myself in i just kept going n going n going n going n going n going n going n going n going n going n going and then I was done still had a little juice left tho so I went again

I bought this to use for a robot I'm designing but there are no specs on this battery. Since it's an RC battery I assume it can handle fairly high loads but I have no idea what specifically is its limit and I'm scared to discover it accidentally.

Got these to power an item that used AA batteries. AA batteries last about a year. These are dead in under 2 weeks. I would be okay with less than a year, maybe even half, but not twice a month. Fail.

Bought two of them as replacements for Ni-Cad battery packs in solar-powered outdoor lights. Plugged in and worked right away. USB charging cable is a nice extra but in my case was not necessary. First real test will be the coming winter with outdoor temperatures as low as -30C. I think they will work fine. Great product!

Item was received when expected and was described. It works well with a motion sensor activated light, powered by a small solar panel. The only comment is that there is no indication/indicator as to how long to initially charge via the USB connector.

The battery pack is in a security light , and is working quite well. It is much brighter than the original pack. This pack had to be forced into the battery enclosure because the cells were not as well shrink wrapped as the originals, but I made it work. For that, I gave it 4 stars. Other than that, so far, so good. I've only had it about 2 weeks.

I had a hard time finding replacement batteries for a couple of Solar Powered Security Lights I bought from Canadian Tire. These batteries fit perfectly and after a couple of months of use are still working perfectly.

I used this 2400 mA battery pack to replace a worn out 1000 mA battery pack in my outdoor solar light. Lasts much longer than original lower powered battery pack that came with the light. 2400 mA battery pack is exactly the same size as the 1000 mA original battery pack, so installation was easy. As a bonus, it also comes with a USB charger to charge the batteries separately if you want to.
