For example, lead-acid batteries should be charged between 50°F and 80°F, while lithium-ion batteries should be charged between 32°F and 113°F. Charging outside of these recommended temperature ranges can cause damage to the battery and reduce its lifespan.
This will suck about one half amp hour from your battery daily at 80 degrees Fahrenheit. This draw, combined with the self-discharge rate, will have your battery 50 percent discharged in two weeks if the bike is left unattended and unridden. When A Battery Is Being Charged. Charging is a process that reverses the electrochemical reaction.
Easy enough, right? But if you do this continuously, or even just store the battery with a partial charge, it can cause sulfating. (Spoiler alert: sulfation is not good.) Sulfation is the formation of lead sulfate on the battery plates, which diminishes the performance of the battery. Sulfation can also lead to early battery failure. Pro tips:
12V Lead-acid battery voltage chart. 12.6 volts or more: A voltage reading of over 12.6 volts indicates that your battery is fully charged and in good condition, so there is nothing to worry about. 12.5 volts: A reading of 12.5 volts shows that your battery is healthy and 90% charged. If your last trip was a short drive, the alternator might not have had enough time to recharge the …
