EBLD Battery D Size Rechargeable Batteries 10,000mAh Ni-MH, Pack of 6 - ProCyco TechnologyClimatePartner certified

Initially, I had purchased and tried the lithium ion battery for lights requiring batteries. Unfortunately, I found the lithium ion did not hold a charge when using them with lights. Lithium battery charge only lasted a week to 10 days. Accordingly, I ordered the NiMH-batteries and I’ve been pleased thus far. The charge level indicators in my devices, show the charge status and I have used them in lights, flashlights, and battery operated trash cans. So far so good! And the real important feature is that they are rechargeable for up to at least 500 times. I consider this a good investment overtime with substantial savings over the throwaway alkaline batteries. So far I have worked only with the D series, but expect to expand the C and AA sizes as well. With reference to the charger, I recommend the EBL, which is specific to their EBL batteries and is versatile in that this charger can recharge numerous EBL batteries as required.

Good batteries. Have bought prior and have been satisfied each time

We bought these specifically to use in electric candles that can be programmed to automatically come on and shut off at specific times. Regular D cell batteries last around 5 to 7 weeks depending on brand. These last around 2 weeks and then need to be recharged. We have 3 candles that use 2 batteries each. Kind of a pain in the butt to take these out every 2 weeks, plug 4 of them into the charger for most of a day, then plug the other 2 in for the night, and then repeat 2 weeks later. There is a savings in having to purchase a 12 pack of batteries every 3 months or so. I don't think it costs much to charge the batteries - don't know. Still evaluating.

Work really good in my D cell powered outdoor motion lights. After a month or two I put them in my EBL charger, hit Discharge, which empties the battery and then gives it a fresh full charge. Not all D cell chargers will charge a battery up to 10000 mAh. Harbor Freight sell a cheap D sell charger but it doesn't charge batteries higher than 3000 mAh so be aware of that. High capacity rechargeable batteries, D cell, can be about $6.00 each so when one goes bad it can give you a sick feeling. That's what happened to me. 2 of my EBL D cells would not charge, and the charger would blink an error icon for those batteries. On a manual battery tester they would not even register. They were too low for the smart charger to charge them. I did a search on google and found Michael Bluejay's Battery Charging FAQ which tells how to bring some current into a low battery so the charger can recognize it an give it a charge. I put the low battery on a strip of metal side by side by a good battery standing up, and then put a piece of metal across to top battery terminals which lets some current pass from the good battery into the low one. Negative to negative and positive to positive. It only took a few seconds but I put my extra low error message battery back in the charger and after analyzing it began the charging cycle. I just saved 2 of my expensive batteries. Very happy. Sometimes a device will drain a battery too far so that really isn't the batteries fault.

1 failed and will not hold a charge for very long. Used 6 of these EBL10000mah D Cells in my Realistic DX-440 shortwave radio. After a few hrs of use one of the batteries was completely drained and didn't have any voltage. The other 5 measured about 1.0V I really wanted to like these batteries but not so sure. UPDATE customer service stepped up and sent me 4 new D cell 10000mah batteries for a replacement. Top notch customer service. They stand behind their product. 2 thumbs up.

I have a very old C. Crane AM FM SW, it's almost 40 years old, and it looks and operates the same way that it did when I unpacked it years ago. It came with a set of C, Crane Batteries (re-chargeable) and I augmented them with a new set of EBL. Batteries (rechargeable). These batteries have a reputation for long life, dependability, and safety from malfunction (leakage) even in areas that have hot and humid weather. I am not saying whether of a jungle in Brazil, but within reason. I have 100% confidence in my EBL batteries, and when used as prescribed I am looking forward to many years of use. Thank You

Got the fast. Just what I wanted!

These batteries like many Chinese batteries are not the capacity that they claim. I have used them for a while, and they didn't seem to work quite as well as I had expected. I finally put them in my Opus battery analyzer. First, I ran a refresh pattern on them. This charges them all the way up, then all the way down, three times to get the batteries into top condition. Then I charged them fully and ran a capacity test on them. I did this with multiple samples, and they always were between 4,000mAh, and 6,000mAh. I have attached a picture of one of the typical test runs.Update - 11/27/2016 EBL support is very responsive, and had concern that I was unhappy with the product. They sent me 6 more batteries. I chose two batteries out of the package and loaded them into the Opus analyzer. After running a refresh pattern which fully charges and discharges the batteries 3 times to get them broken in and into optimal condition, sadly they performed even worse than the first sample. They were 2743, and 4113mAh. While EBL has great support, they like many foreign manufacturers they appear to blatantly lie about their capacity. Additionally the previous test that I ran on that analyzer was some Ray-o-vac AA batteries, which performed within 10% of expected. This proves that the analyzer is working correctly.For those geeks out there, I ran the test at 500mA (20h rate if the batteries were really 10,000mAh as specified) on an Opus BT-C3100 with software ver 2.1You can read about the analyzer here:[...]
