[NB FL] Cambio batteria e tubi sfiato

[Kublai]

Grazie ragazzi per le risposte e scusate il ritardo della mia.

@"Kublai" : mi sono letto i vari link che mi hai mandato e mi sono fatto una cultura
Devo dire, da ignorante sul tema, che mi pare ci sia molta confusione, a partire già dal definire il tipo di batteria: es. il sito sandiegomiataclub.org dice chiaramente che NON è una batteria Gel mentre su altri siti (inclusi rivenditori nella pagina prodotto) parlano proprio di batteria Gel

Sono d'accordo, forse si confondono per via della lettera G nella sigla AGM   che invece sta per Absorption Glass Matt = (a elettrolita assorbito) senza acido libero.

Il link che ho postato è molto chiaro su questo punto e spiega bene le differenze tra i vari tipi di batterie:

"In a normal lead-acid battery, the electrolyte is sulfuric acid in sufficient quantity to cover the lead plates in each battery cell. This type of battery is referred to as a wet or flooded cell battery. The main drawback to this type of battery is the continued maintenance and possibility of spillage of acid during maintenance or an accident.


About 1958, attempts were made to immobilize or fix the electrolyte in the cell of the battery using various methods. One of these was to use silica gel to bind the water present in the electrolyte solution into a jelly. Just imagine a battery full of cherry JELL-O. These type of batteries are used in many applications and are referred to as gel cells.

For the record, the Miata battery is NOT A GEL CELL.

In 1985, when the Miata was taking shape in Irvine, a new battery technology was being used in military aircraft. The paramount considerations of power, weight, safety, and reliability were the selling points of this new type of battery. The new technology was AGM or Absorption Glass Mat. This technology was an evolution of previous battery technologies, including gel cells.

In AGM sealed batteries, the acid is absorbed between the lead plates and immobilized by a very fine fiberglass mat. This glass mat absorbs and immobilizes the acid while still keeping the acid available to the plates. This allows fast reaction between the acid and plate material. The intimate relationship of the electrolyte-filled mat and the lead plate, allows the construction of a smaller battery, using less electrolyte and metal plates. This means a smaller battery with nearly equal power ratings to a wet-cell battery of larger size and weight."

Quindi per non avere problemi: 

Staccare almeno il polo negativo prima di lunghi periodi di inutilizzo,
Non avviare  con cavi da altre auto (jump start) o usando avviatori-starter portatili.
No a ricariche rapide !
Ricaricare a 1ah o meno per 18-24h
