Lead car battery

A lead battery for a passenger's automobile lasts about 4 to 5 years at the shortest if the way of use is adequate and charging system works well.

SXE10 TOYOTA Altezza is used very seldom once a week for a very short period of time, so it has a tendency to be in lack of charging phase, in the necessity of additional and external charging to keep the lead battery in healthy condition.

But remember here the dangerous chemical phenomena under the such adverse condition, covering the electrical terminal surfaces by some chemical sulfate thin film. Inconveniently this film prevents the battery from performing a good charging cycle and attaining full charging.

So, the key to survive the battery well is to eliminate the sulfate thin film from the electrical terminals.
In order to remove this covering chemical thin film from the terminal plate inside of dilute sulfate acid, some very special technique and method are required.

Pulsing charging is the best way to awake the dead lead battery, at adequate voltage, with the suitable nature of the pulse, duration and interval and the charging time of period, the requirements of the charging method was decided under many experimental trials with many failures for tens of years.

First of all, the warping phenomena of the electrical terminal plates must be avoided leading to the case fracture. High voltage often invited this kind of voids.
