Bosch Kl 1208: Battery Charger Manual Exclusive |top|

Share the you're trying to charge (e.g., AGM, Gel, or Standard Lead-Acid)

Sandwiched between safety warnings, the manual specifies: Do not charge at ambient temperatures below 10°C (50°F) or above 40°C (104°F). Why exclusive? Because many users charge in garages or sheds. Below 10°C, the charger’s delta-V (voltage drop) detection fails, leading to overcharging and cell damage. Above 40°C, the thermal safety cutout triggers prematurely, leaving you with a half-charged battery. The manual’s hidden advice: Charge only in conditioned spaces. bosch kl 1208 battery charger manual exclusive
