Why lawn mower battery keeps dyingApart from time, there are various reasons your lawn mower battery keeps dying. They include the following: Extremely cold or hot weatherExtremely cold or hot weather is the main reason why lead acid batteries die. Cold weather slows down important chemical reactions in the battery. Studies have established that at 32°F, a car’s battery loses about 35% of its strength. And at 0°F, it loses up to 60% of its strength. Hot weather is also a great threat to your lead acid battery. In high temperature, a car battery loses most of its important liquids through evaporation. Hot temperature also accelerates the rate of corrosion. This means your lawn mower battery is not safe in hot summer conditions. Poor battery maintenanceJust like your lawn mower engine, the battery also needs great care and maintenance to remain in good condition. When you tune up your lawn mower, also remember to check on your battery. Ensure it has enough water, terminals are clean and no liquid or gas is leaking from the battery. Over time you will notice a powdery substance on the battery terminals. This is a corrosion that forms when cables are loosely connected on the terminals or when leaking gases from the battery are reacting with the terminals. This usually interfere with the ability of the starter motor to draw current from the battery as well as the ability of the charging system to top the battery off. A proper battery maintenance involve cleaning its terminals with a solution of baking soda. More so, you need to tighten loose cables on the battery terminals and fix any damage that causing internal gases to escape and react with the terminals. Components left onHeadlights and other accessories that rely on battery can drain it overnight when left on. Most people forget to completely turn off everything before shutting off the engine. When parking your lawn mower after use, double check everything or disconnect battery cables for longer storage.

If one of the parts fails, then your battery will not be properly charged. You will have problem starting the lawn mower or using some features. OverchargingOvercharging a lawn mower battery means leaving it connected to unregulated charger for too long. This not only weaken the battery’s ability to store charge, there is also a risk of permanent damage to the battery or personal injuries from boiling toxic fumes or battery explosion. Using a modern charger that shuts off when the battery is fully charged is helpful in preventing a lawn mower battery from overcharging. If the battery is not completely dead, you can also jump start it with a car or another battery.
