C Size Battery 1.2V 5000mAh High Capacity NiMH Rechargeable Battery for LED Flashlights Kids Toy and More (8 pcs)

I bought an auto-open trash can requiring four ‘C’ batteries. I used to use ‘C’ batteries in my Roomba virtual wall but a trash can is an item that is used many times in a day and I didn’t want to be replacing batteries often. I found these batteries to be very useful and effective and they lasted a long time between charging (more than several months) and while I bought an extra set for between charges but it really wasn’t necessary because of the length between charges is longer than I expected.

These hold the charge for a good amount of time in my Luminara candles.

Device Test: 8 LED Holiday Candelabras for windows 3 LED "flickering" lights per Candelabra 6 hours per night via internal timer 3 size C Tenergy rechargeable batteries per Candelabra [3x8=24 batteries] I purchased 3 packs (24 batteries) to fuel 8 LED window candelabras. Regular alkaline batteries will last about 24 days, running 6 hours per night via timer, which I usually start the second week of DEC to get through New Years. Those get disposed, and due to cost of new batteries, I usually put the candles away until next year. This year I started the candles the second week of NOV, and plan to run them all winter until sometime in March. In comparison to alkaline disposables... I should only need to recharge about five times. I'll provide an update in a couple of months on how long they last before needing recharging, and how many times I need to recharge. What I can say is that they charged very well, with no "duds". They have been working now for almost a week, and appear to be discharging just fine. The batteries arrived undamaged, with no leaks or obvious defects.

This review is for both the Tenergy T-1199B AA/AAA/C/D/9V NiMH NiCD Battery Charger and Tenergy 8 pcs C Size 5000mAh high capacity high rate NiMH Rechargeable batteries...I purchased these together (from Battery Superstore) for use in my older GE 3-6025A Stereo "Boom" box. I am on my first charge of the "C" batteries which have lasted over month now with daily use of about an hour or two. I used to get about 2-3 months use from standard batteries. I am hoping to get the same or better results from these batteries and charger. Longevity and maintaining a charge is the real test of quality...I will update regularly for at least the first year of use. Using the charger, the batteries already appear to be of good quality and able to sustain a solid charge. The charger has performed well although it is large and rather slow. In fact, following the instructions, when charging "D" batteries you have to charge "D" batteries twice. And if this isn't difficult enough, taking 16 hours, you have to watch the time yourself then remove the batteries from the charger after the first 8 hours, unplug the charger, replug in the charger and reinsert the "D" batteries for another 8 hours. Also, 9V batteries are charged entirely on a manually (you time and remove batteries) cycle taking 10-15 hours to charge and, of course, the instructions warn you to remember to remove the 9V batteries from charger as not to overcharge and damage the batteries. Otherwise, the charger works just fine and easily for other batteries. The charger takes about 8 hours to fully charge batteries and then automatically enters a "trickle" charge mode. So, for my purposes, using these "C" batteries, I am happy enough with the charging capabilities of the charger. So far, I am happy with both of these Tenergy products - 3 Stars for the Charger, 4 Stars for the batteries. To reiterate, I will update any concerns or issues that may occur during at least the next year.

When my son was born he used a mobile/light show to sleep, this thing eats batteries, so the quickest and most logical solution was rechargeable batteries. We bought a set of these two and half years ago, a few months ago they started losing their edge a little, that is to say they slowly and surely started to require swapping out less and less (used to last for a week or longer). We purchased a new set of these and they're now running back to back for 8-12 days a time. He still uses the mobile for the lights. Considering the constant recharges we've made over the past few years and the zero issues we've faced with these batteries and taking into consideration the costs of eight of these, I found this product astonishingly good value. Considering that we also have the AA series batteries as well with the same return on investment, I would go as far to say that I wouldn't purchase rechargeable batteries from any other vender, with the assumption of "sticking to what you know".

A dirty little secret of rechargeable batteries is that many C size rechargeable batteries are actually AA batteries with an empty shell around them. This effectively gives you a significantly lower charge than you need for devices that require C size batteries. Not so with these Tenergy C size rechargeable batteries. They are true C size and hold a charge to prove it. We are using six of these in two cat toys (the Cat's Meow), and the charge lasts for a great amount of time. The batteries are slightly shorter (1mm) than standard alkaline C size batteries, causing issues with some chargers. A workaround for this that has been posted is to use tin foil to close the gap. We use a MAHA MH-C808M charger for all our recharging needs, and the Tenergy C batteries fit in them snugly without use of foil. I'd suggest a decent charger (like the aforementioned Maha, which is a great and nearly-universal charger) for these. Best C rechargeable batteries I have ever bought.

Expect to charge these right when you want to use them. They don't hold charge long term.

Excellent quality long lasting

It takes a long time to charge due to the high capacity. But it seems to behave very well as it has more capacity than expected. So much so, that I decided to buy some AA/AAA batteries of the same Tenergy brand. Unlike the EBL batteries which are slightly larger than the standard size, the Tenergy batteries fit into my electronics very well.

Great product. I've ordered all sizes. These hold a charge a long time. Love them. I also bought their 4 battery charger which charges only 4 at a time but super fast. Way faster than my Eveready 8 battery charger. Will always buy only these. thanks.

Use these in my Roomba virtual walls. They last at least 2 months and have saved me plenty of money over buying traditional C batteries. These do NOT hold their charge while in storage, so it's better to charge them right before you use them.

Good product and even better delivery time thank you

Charge de longue durée
