Initial capacity checks out. Will update rating based on LSD-ness and how well they hold charge
on March 3, 2015
Currently, Amazon is selling charger and/or batteries in the same product listing. Makes the reviews confusing, to say the least.
I bought a set of 8 EBL 2800mAh batteries.
Upon receiving, I gave them a full discharge (at 350mA) followed by a full charge (at 700mA).
The pictures show the resulting voltage and capacity at the end of the charge cycle, while still in the charger.
As a baseline (to prove that my charger is still working correctly), I've also tested my trusty Eneloop batteries (identical conditions), which are rated at 2000mAh.
I've seen reviews claiming that these are not Low Self Discharge batteries, despite the manufacturers claims that they are LSD.
Less than 1 day after charging and without any use, the voltage had dropped to about 1.37V. But that's not totally unexpected, as NiMH batteries tend to do that. Their claim to fame is that they can hold 1.2V during heavy operation much longer than Alkalines.
I will have a chance to test how well it holds the charge and their LSD-ness soon and will update this review accordingly.
- Confirmed these are not true LSD. They discharge much quicker than the Eneloop, which are true LSD.
Not sure if the manufacturer changed the description recently, but it says "Improved low self discharge makes it still maintain 75% of capacity after 3 year of non-use".
Technically, they could be right. I don't have an older version to say that these are not improved. And I don't plan to leave them unused for 3 years just to test the claims, but I offer some numbers below.
- I bought these batteries for their capacity. I used them in my DSLR camera, which is a power hog. I'm OK with having to charge them before each use (because I have multiple sets of batteries, if you don't you may be caught off guard by them being empty when you need them). The Eneloops didn't last an entire soccer game, most of the time. These will last the entire game, most of the time. That's an improvement, I suppose. I still have the problem that half way through, the camera displays a low battery sign, but they still work. I suppose that's a problem with my camera, even though I have this same problem with 2 different cameras.
- After soccer season was over, I put these batteries on a garbage duty. I have one of those sensor activated garbage cans that opens by a hand wave. It a low power, long term application, the exact opposite of the DSLR duty. Alkalines would last 4-6 months. These last 3, at most. It's clear that they fail due to self discharge, not power use.
- I recently put them in a full discharge/recharge cycle, similar to what I did when I first received them. At the end of the cycle, the average voltage (while still in the charger) was 1.46V (pretty much the same as new), but the capacity had dropped to an average of 2700 mAh.
In summary, buy them if you find them on sale or much cheaper than Eneloop XXX (the high capacity version). They work, but they are not LSD.
