Like all products of the German concern Bosch, batteries are reliable, high-tech and high-quality products. Be very careful when charging Bosch batteries to avoid overheating of the electrolyte.

Instructions
Step 1
If the battery is low, remove it and try charging in a warm room. Predetermine the capacity of the Bosch battery, which is indicated on the battery case. If it has a conventional design with acid electrolyte, then when charging, set the current on the charger on the charger, which is no more than one tenth of the battery capacity. For example, if you need to charge a 65 amp-hour battery, adjust the charging current on the charger to no more than 6.5 amps. In this case, be sure to ensure that it does not overheat. Remove the battery covers. If the electrolyte boils in it, the battery may be permanently damaged. It takes 10 hours to fully charge the battery.
Step 2
A special feature of modern car batteries from Bosch is that many of them are helium-based. The electrolyte in the banks of such a battery is in a condensed state. Such batteries are more environmentally friendly, easier to maintain, and have increased capacity. A special valve system allows excess gas to be released from them. But when charging, avoid overheating the gel, otherwise the battery will definitely fail.
Step 3
In sealed helium batteries, the charging current is set at 2.5% of the battery capacity and takes longer to charge. For a 65 amp-hour battery, the charging current will be more than 1.625 amperes, and the charging time will be 40 hours. In this case, be sure to control the temperature in the battery banks. If the gel is allowed to turn into a liquid, the battery will become unusable. Therefore, if you do not need the fastest possible charging, use the lowest charging current possible.
Step 4
If the charger has a quick charge function, it can only be used with liquid electrolyte batteries. But even they cannot be constantly charged in this way, as this will shorten the battery life. This charging method is strictly prohibited for helium batteries.
