Now there is a VARTA battery for every
pocket. The ideal battery for older, smaller vehicles with lower
electrical requirements, this battery offers premium VARTA quality at
an unbeatable price. It is just the battery to match the depreciating
value of older cars in the repair market.
STORINING
AND RECHARGING FILLED BATTERIES
To ensure that the batteries
safely reach their maximum shelf life in the unlikely event that this
becomes necessary, the average annual storage temperature should be 15
°C. The short-term
storage temperature must not exceed 25 °C.
Batteries should be sold according to the first-in, first-out
principle. Therefore, they are helpfully
1. Installationcolour coded according to the date of manufacture (please see colour coding table). The battery should be installed in the customer’s vehicle no later than a total of 15 months from the date of manufacture (please see colour coding table). The terminal voltage should be greater than 12.2 V. 2. Recharging The battery needs to be recharged when the terminal voltage has fallen below 12.5 V due to extended storage periods. When recharging the battery, you must observe all relevant safety regulations (especially the requirement to wear safety glasses) and carry out the work in a sufficiently ventilated room. 2.1 Checking the terminal voltage The terminal voltage should be checked two to four quarters after the date of manufacture. If the terminal voltage has dropped below 12.5 V, the battery needs to be recharged to between 12.7 and 12.8 V before being stored further. 2.2 Measuring the terminal voltage The terminal voltage is to be measured with a digital multimeter (1 mV resolution) at a room temperature of approximately 20 °C. <> 2.3 Recharging recommendations Should the terminal voltage drop below 12.5 V, the battery must be recharged. The recommended charge current equates to one tenth of the battery’s nominal capacity (e.g. 8 A for a battery with a nominal capacity of 80 Ah). How long the battery needs to be recharged depends on how it’s going to be used afterwards. If the battery is going to be installed immediately in a vehicle, a short recharging period is generally sufficient to prepare it for use (i.e. a terminal voltage of between approx. 12.2 and 12.5 V, measured approx. one hour after the recharging period is complete). If the battery is going to be stored for a further period, then a maximum possible state of charge should be reached (see page 21). A 44 Ah battery with a terminal voltage of 12.45 V can be charged to approximately 100 % in 2.7 hours with a recommended charge current of 4.4 A – equal to one tenth of the battery’s nominal capacity(Uo terminal voltage = 12.8 V). The charging time falls proportionately with the rise in the current the battery can supply (e.g. when the current is doubled to 8.8 A, the charging time is reduced by half to 1.35 hours). Overcharging is to be avoided at all costs, however, as it leads to permanent battery damage. The terminal voltage should always be measured at least one hour after recharging (please see 2.1–2.2). |
