Drying of the electrolyte: Naturally, the water contained in the electrolyte evaporates a little. Valve regulated lead acid (VRLA) batteries promote its recondensation, which reduces the need for additional distilled water (unlike open batteries). But, once the battery is charged, a supply of current initiates the electrolysis of the water with the formation of oxygen and hydrogen gas. In a VRLA battery, beyond a certain pressure, safety valves let the water escape permanently. This is problematic because topping up with distilled water is not possible.

Définition du message (Fonctionnement, entretien et régénération de batteries au plomb)
*'''Asséchement de l'électrolyte:''' Naturellement, l'eau contenue dans l'électrolyte s'évapore un peu. Les batteries VRLA favorise sa recondensation, ce qui réduit la nécessité d’appoint en eau distillée (contrairement aux batteries ouvertes). Mais, une fois la batterie chargée, un apport de courant amorce l'électrolyse de l’eau avec formation d’oxygène et d’hydrogène gazeux. Dans une batterie VRLA, au délà d'une certaine pression, des soupapes de sécurité laissent s'échapper l'eau de manière définitive. Ceci est problématique car l’appoint d’eau distillée n’est pas possible ! 
{{Idea|Comment l'éviter ?
*Éviter les surcharges: vérifier sur les fiches techniques que les courants et durées de charges ne sont pas trop importants
*Éviter les températures élevées: aérer ou isoler le local batterie, laisser un espace entre chaque batterie.}}
