Batterijservice Reviews 37

Shipping costs are low due to enveloppe shipping. Therefore even a single battery can be cheaper than in the supermarket, although I recommend against sending just a single battery. You probably need more.
We bought very affordable 1000mAh rechargeable AAA which performan promisiyso far.
We also ordered a small battery for a thermometer. This did not work; although the voltage was high enough, power seemed to drop as soon as the thermometer was switched on. We explained this to batterijservice and without further hassle they promised to send us a battery of another brand. This one arrived within a week and worked perfectly.

Bonjour l'équipe et merci pour votre travail.

Je suis partagé parce que j'ai été agréablement surpris par la rapidité de la livraison, je m'y étais pris en avance, j'avais pas prévu que ça arriverait si vite !

En revanche j'ai reçu mes 4 batteries 18650 avec une tension à peine supérieure à 3.41V. Ce n'est pas complètement dramatique mais ce sont plutôt les signes d'une livraison qui aurait pris du temps ou bien d'un stockage des batteries sur une longue durée.

Voilà ça paraîtra un détail pour certains mais pour quelqu'un quasi maniaque au niveau de l'entretien de ses batteries, cela retire les deux étoiles je dirai.

Je pense malgré tout que je commanderai de nouveau mais je vérifierai ce même point car si avec une mauvaise gestion de la charge une batterie peut ne durer qu'un an ou deux, avec de bonnes méthodes on fait durer ces mêmes batteries 10 ans voir plus !

J'aimerai bien savoir à quelle tension vous les stocker en général dans vos entrepôts, si mes batteries étaient un cas particulier ou non et combien de temps elles auraient été stockées.

Bonne journée et bon courage !

Hello team, and thank you for your work.

I’m torn because I was pleasantly surprised by the speed of the delivery. I ordered in advance, not expecting it to arrive so quickly!

However, I received my 4 batteries (18650) with a voltage just above 3.41V. It's not a complete disaster, but it does suggest that the delivery may have taken longer than expected, or that the batteries were stored for an extended period.

This might seem like a minor detail to some, but for someone like me, who is almost obsessive about battery maintenance, it’s enough to deduct two stars.

Despite this, I think I’ll order again, but I will definitely check this same point next time. Poor charge management can lead to a battery lasting only a year or two, while good practices can make these same batteries last 10 years or more!

I would like to know at what voltage you usually store them in your warehouses, whether my batteries were an exception or not, and how long they might have been stored.

Have a good day and good luck!
Arthur

EDIT: I completely agree with your response but for me IATA only stipulates 30% SOC which is not directly related to tension but for a 18650 it would be:

100% SOC: +/- 4.2V
50% SOC: +/- 3.7V - 3.8V
30% SOC: +/- 3.5V - 3.6V

And I was expecting something closer to 3.5 even 3.6 and 3.4 is more 20% If they stayed a long period at 20% it's not perfect. I know you can make them last a long time compared to our old technologies but still, they last even longer if you avoid keeping them under 20% and above 90% for extended periods

Sorry to bother, have a nice day.
