    Quelles que soient les raisons, vous pouvez toujours raviver une batterie qui ne semble plus fonctionner plutôt que de la remplacer pour économiser de l'argent.

    Il n'y a que huit étapes simples au total.

    1. Préparation

    Le processus vous oblige à préparer plusieurs ingrédients. Ils comprennent des gants en caoutchouc de sécurité, des lunettes de sécurité, un chargeur de batterie, un démarreur de saut, un tablier, des seaux à eau, une protection des yeux, etc.

    La reconditionnement de votre batterie morte nécessitera d'assembler des outils de nettoyage simples, du bicarbonate de soude, etc.

    2. Nettoyage des bornes de la batterie

    En raison du matériau métallique, les bornes de batterie sont souvent la zone avec des couches de rouille. Vous pouvez les nettoyer en utilisant une brosse avec un mélange d'eau et de bicarbonate de soude pour éliminer la rouille .

    3. Vérification de la tension

    L'utilisation d'un compteur de tension vous aide à vérifier l'état de la tension de la batterie.

    Après avoir connecté les terminaux avec cet appareil, il est temps pour vous de vérifier la lecture. Un processus de reconditionnement peut relancer la batterie si la figure est inférieure à 12,6.

    4. Nettoyage de l'acide de la batterie
