Rechargeable Battery Match-up: Ansmann Versus Sanyo Eneloop

sanyo eneloopWhen it comes to rechargeable batteries, it’s hard to tell if premium brands like Sanyo Eneloop can beat out more value-priced contenders like Ansmann. Take a look at this match-up between the two:

It is true that we have been espousing our love and extolling some of the virtues of the Ansmann rechargeable batteries. This affair began with the AA high-capacity, moved on as we found their ability to perform with R/C vehicles, and has culminated in looking at the larger batteries in their line.

What we needed to know next was if this was just a reaction to the new and different. We had to be sure that we were not being lured in by a fresh face on the market. To do this, we called on an old friend. A battery that has stood by us for years, in the face of much adversity. We needed to call out our Ansmann rechargeable batteries and see how they performed, not just in the lab or on the street, but when put up against the Sanyo Eneloop rechargeable batteries.


Contender Background – Eneloop:

If you have been working with modular power for any time, you are no doubt aware that Sanyo Eneloop has long been the gold standard for their line of rechargeable batteries, as well as battery chargers. For years, if you asked anyone in the field “who is the best?” everyone – including almost all of us – would have happily pointed to the Sanyo Eneloop and walked away, secure in the knowledge that we had done right by them.


Contender background – Ansmann:

Ansmann has come on to the scene to much fanfare. They began in the UK in 1991 with their line of products. It has only been recently that those down under have been able to get them from local vendors. Previously they would have been imported.


The reason for the splash they have made when they came to the beautiful shores of Australia is that they managed to throw around a lot of power for a relative newcomer. Anymore, it is not as easy to hand someone an Enloop and say it is the best.


The Test:

First and foremost, we try to be fair minded, so we made our test double-blind. No one that tested the batteries could know which of the rechargeables they were using, because there is still some bias by users toward one product or another.


We tested on a few very simple but important comonents:

ñ Actual Power Output

ñ Discharge Rate Over Time

ñ Cost

ñ Charge Rate


To continue giving both competitors an equal advantage, we made sure to choose comparable models so that none could have an unfair advantage. The products selected were:

ñ Sanyo Eneloop AA Rechargeable

ñ Ansmann maxE LSD Rechargeable Batteries


You’ll be able to see by clicking those links that we decided against choosing the higher end models, as we wanted a happy average to determine the best deal, the most average power for the average user, and the discharge rate that could be expected from “normal” rather than professional grade batteries.



Actual Power Output:

Eneloop clocked in at a steady, solid 2000 mAh, which is great for power, while the Ansmann, though making a declaration of 2100 mAh actually discharged closer to 1900 mAh. Not a notable difference, but if you need lots of power quickly, go with the Sanyo.

Winner: Eneloop by 100 mAh

Discharge Rate Over Time:

The modestly lower output of the maxE made it able to boast a longer life prior to recharging. We managed to get 200 shots with a digital camera using the Sanyo Eneloop rechargeable while we got almost 300 (289) with the maxE.


Both models still showed a full charge after 100 charges, making them neck and neck.


The other difference is with regard to shelf-life. The Sanyo holds a 90% charge after one year on the shelf, while its competitor managed a 95% thanks to their LSD (Low Self-Discharge) technology.

Winner: Ansmann by 89 digital stills and 5% Self-Discharge.


This was simple: Eneloop: AUD$21.99, Ansmann: AUD$18.99.

Winner: Ansmann by AUD$2.00


Charge Rate:

This test was strangely difficult, as a batteries charge rate changes from charger to charger. We chose to use the same Energizer Charger for both batteries. Both gave a full power output after 15 minutes.

Result: Tie. How dull.

It is as simple as that: For strong but short lived, spend more on a Sanyo, for longer life and lower drain. Get yourself a nice maxE and save a little money.
