Définition du message (Fonctionnement, entretien et régénération de batteries au plomb)
*'''Détection et prévention des décharges profondes''': La durée de vie d’une batterie est en relation directe avec la profondeur de décharge DoD. Il est donc très important d’'''empêcher toute décharge à plus de 50% !''' <br />
**<u>Comment connaitre le niveau de charge</u> (SoC)?
***La mesure du voltage ne suffit pas. Trop de facteurs différents agissent sur la tension de batterie.
***Il faut utiliser un [https://www.victronenergy.fr/battery-monitors moniteur batterie]. Il calcule la tension mais aussi les courants de charge et de décharge. Cela permet de calculer l'état de charge en direct.
**<u>Comment éviter les décharges profondes</u> ?
***L’idée est de contrôler le niveau de charge (SoC) et de déconnecter les charges de consommation dès que celui-ci passe sous un niveau établi.
***Utiliser un protecteur de batterie/[https://www.victronenergy.fr/battery_protect/battery-protect Battery Protect] ou un régulateur de charge solaire paramétrable, pour les équipements en courant continu DC.
***Utiliser le relais à contact sec de votre moniteur batterie s'il en est équipé.
***Paramétrer le seuil de basse tension batterie sur votre onduleur pour les équipements en courant alternatif AC (bien lire la notice).
*'''Faire attention à la température''': Ce facteur a une influence très importante sur la durée de vie des batteries ! Il est très important de garder les batteries '''à des températures « fraiches »''' , environ 20°C. 
**<u>Local technique</u> : Choisissez toujours la pièce ou l’endroit le plus frais. Ne laissez jamais les batteries exposées au soleil direct. Si ce lieu est encore trop chaud, il faudra très sérieusement envisager une ventilation rafraichissante du local ou du container batterie.
**<u>Aération et ventilation</u> : Toujours garder de l’espace entre les batteries (environ 5 cm), ne pas les mettre les unes contre les autres. Si les batteries sont à l’intérieur d’un coffre à batterie ou dans une armoire, il doit y exister une circulation d’air.
**<u>Compensation de température:</u> Lorsque la température dépasse les 30°C ou est inférieure à 10°C durant une longue période, il est nécessaire de modifier la tension de recharge.
