You do all the activities at your own risk! Supplementing the electrolyte level with distilled water extends the life of the battery. While maintaining the correct battery conditions, the electrolyte level does not decrease, so you do not need to refill it with distilled water, but often the problem occurs with the car's electrical installation, eg there is too much charging voltage by the alternator or rectifier. Too intensive charging of the battery may damage it and increase the temperature of the electrolyte (and, as a result, its excessive loss). Therefore, the control of the electrolyte status is important and will allow to decide whether to top up with distilled water or not. If the "Magic Eye" of the battery shows a white color, it indicates a low electrolyte status, which should be supplemented, for example, like a film, when it is not possible to remove the cover. However, the most important is to locate the cause, i.e. verify the charging of the battery by the alternator, whether the charging voltage is close to 14.4V at idle speed and importantly at 2000 and 3000 engine revolutions. If we are dealing with a voltage of about 14.8 and higher, it will mean that we either have a faulty meter, the battery in the meter is worn out, or the alternator can be repaired / replaced. In this particular copy of the battery you can not pry open and batten, because it will break, come the other similar have such a possibility. The concrete one I have, there is no option for opening, so you have to re-start if you want to top up the electrolyte level. I hope that my film will be useful for you when you notice a drop in electrolyte in a maintenance-free battery.
