EBL C Size C Cell 5000mAh Ni-MH Rechargeable Batteries, Pack of 2

There doesn’t seem to be very many objective, evidence based reviews here – so I thought I’d post my findings to help shed some light on these EBL rechargables. Since Amazon shows both D cell and C cell reviews here, I’ll combine mine here, too. I bought 20 D’s and 16 C’s for my vintage radio collection and a few Mag-Lights I have…There isn’t a real choice for name brand D and C cell rechargeable batteries (as there are for AA and AAA). This is why I chose the EBL D cell rated at 10,000 mAh, and the C cell rated at 5,000 mAh.Duracell, Eneloop, and LADDA do not sell rechargeable D and C cells at all. Energizer does, but these are merely glorified AA’s, as the capacity for both their D and C rechargeables are a meager 2,500 mAh. However, both Tenergy and Amazon Basics do offer rechargeable D and C with an advertised capacity of 10k and 5k mAh, like EBL does.For my testing I used two newly bought XTAR Dragon VP4 Plus battery charger/tester’s. This is one of the best out there as it is capable of charging/testing/refreshing anything from AAA to 18650 (and probably more), both NiMH and Lithium, in four independent bays. Another great feature of this charger/tester is that it’s wide enough for four D cells simultaneously. In test mode, this unit will top off the battery to fully charged, then discharge, and finally charge the battery from discharged to 100 percent. This enables the XTAR Dragon to calculate the number of mAh’s both charged, and more importantly, discharged. The discharged number of mAh’s is more important because this is the performance of the battery in use, or rather, how many mAh’s it “gives” versus “takes”. In addition to the mAH charge/discharge rate, the XTAR Dragon can also measure the output voltage and battery resistance in Ohms.This is only the first part of my testing, as I plan to update this review with future results in a year and beyond. All batteries were individually numbered so as to keep track of which one is which for future testing.Upon delivery of my brand new EBL D and C cell batteries, I ran them through the XTAR Dragon’s test mode.The D cells actual charge capacity varied from 10,000 mAh’s (for six of the 20) to a low of 7,216 mAh’s, which averaged out to 7,801 mAh’s (78.01% of advertised capacity). The discharge rate ranged from a high of 7,707 mAh’s to a low of 6,971 mAh’s, which averages out to 7,287 mAh (72.87% of advertised capacity).The C cells fared a little better. For the charge rate they ranged from a high of 4,546 mAh’s to a low of 4,164 mAh’s, which averages out to 4,303 mAh’s (86.1% of advertised capacity). The discharge rate ranged from a high of 4,553 mAh’s to a low of 4,026 mAh’s, which averages out to 4,203 mAh’s (84.09% of advertised capacity).As mentioned earlier, I numbered all of the batteries (20 D cell and 16 C cell) for future reference/testing. I hope to measure in the future how quickly or slowly the batteries discharge over time (percentage) without use for a year. I also hope to see how quickly the actual capacity degrades over time/charging cycles.As I have not bought or tested the Amazon Basic’s or Tenergy rechargeable D and C cell batteries, I cannot compare the EBL’s performance to them. But I would guess that they are probably manufactured in the same factory, or if not, under similar conditions. As such they are probably nearly identical to EBL batteries for performance, which makes EBL batteries a good value, indeed.

You really can't beat these. They have paid for themselves in the last two charges. They last as long as major brand batteries. I used the C size batteries in my daughters light up fake fish tank to help her sleep. It eats batteries so rechargeable is the only way to go.

Got the fast. Just what I wanted!

Update 19JL2018 -EBL reached out to me about the concern and rating I wrote. The sent me a new set.A little background of the original set I received. 2 out of 6 had high impedance almost 1kOhms.The other 4 were less than 200 Ohms. The 2 high impedance batteries voltage was less than 1 voltwhile the other 4 was slight over 1 volt at time of delivery. After about 5 recharge cycles, I noticed that my chargeindicates capacity below 4000 mAh (some where around 3500-3750 mAh). That was when I wrotemy original review. The reason I gave a bad review was mostly on the performance of these rechargablebatteries compared to alkaline batteries (Duracell) my wife bought. The application is for my son's PolarExpress "Ready and Play" train set. This train set use 6 C cell batteries in series. So, the performance ofthe battery set rely on its weakest link. I believe due to these 2 suspect batteries, my son got about the sameuse out of these set as an alkaline set.After over 10 recharge cycles, my charger shows that most of these batteries are about 4200 mAh.Of the new set received, all 6 batteries impedance below 200 Ohms and comes with 1.2 volts. My charger indicatescharge capacity of about 2900 mAh for these batteries. Full charge voltage of about 1.39 volts for all 6. Since thesebatteries come somewhat precharged, it is hard to know how much capacity left in them before charging. Also, it istoo soon to say until I get at least 5 charge cycles out of them. This set seems to perform strong for first charge. I'llhave to wait and see after 5 -10 recharge cycles.Other thoughts -If I could get 4,200 - 4750 mAh on these batteries, that is pretty good. Not as claimed, but not far from it. Duracell andEnergizer have rechargeable C cell batteries but they are rated around 2,200 - 2,500 mAh. Then one may as well getAA rechargeable batteries with 2,500 -2,700 mAh and use C cell adapters. AA rechargeable batteries are a lot cheaperthat C cell due to demands. Even the AA rated 2,500 mAh may not be 2,500 mAh, depending on brand. Which meansyou may have to replace/recharge twice as often. Sanyo/Panasonic typically under rate their battery capacity. This wayif their MFG quality control is not as tight, it gives them a wiggle room to say that their worst battery still meet their rated capacity.I understand that every manufacturer have their fair share of production and quality control issue. That said, I give kudos toEBL end consumer team for reaching out to customers and take their feed back seriously. This is the start an improvementplan for company's quality and image. If this team can relay this information back to the R&D and MFG folks so that they canmake improvements, I see EBL can be up there with the big boys in the battery industry.Final note -Recharging alkaline batteries will get messy. They all leak at some point in time, it is a matter of when.Brand name like Duracell can be charged like 5-6 times before they start to go bad and leak. Others likethe ones at dollar store can leak even before you try to recharge.So, if you have power hungry electronics, select the right type of rechargeable batteries instead of tryingto recharge alkaline. It is not a good solution.--------------------------------Original Post:Does not have the capacity it claimed.Have about the same capacity as Duracell C alkaline battery. Very disappointed.Runs my son's Polar Express train about the same length of time as alkaline battery! Even after multiple charges. I charge the Duracell batteries with an alkaline battery charger and was able to run for about the same. I might as well use AA adapters and use good high capacity AA rechargeables.These EBL rechargeable C batteries are not cheap either.

Thought I would give this brand of rechargeable batteries a try and I really like them, a lot. Easy to keep on hand in my organized case. Also, love my EBL rechargeable station. Fast & efficient! When my flameless candles start getting low I just plug in and place the batteries in the strategic spot and the light comes on and starts to flash. It lets you know by the lit up lines where your at if battery is real low or semi- low. It takes about 4 hours depending on battery usage. It has been working like a champ! Highly recommend, because, in the long run, you do save money and time by using these rechargeable batteries over and over again. And having them available rather than running to the store is a plus. I recommend this brand 100%.Now that’s smart shopping! :)

EBL has never disappointed me

I have a variety of brands of rechargeable batteries, though the majority of them are now EBL. EBL batteries seem to hold the charge longer than others. Also, maybe of most importance, their customer service is 5 star. They reach out to YOU if you mention a problem in the review of their products. I don't order anything but EBL now.

Great product - reasonably priced.
