It also increases the risk of clogging the deck.<\/li>    <li><strong>Don&#8217;t cut overly tall or thick grass in one pass<\/strong>: Like cutting wet grass, this strains the motor. Raise the deck and make multiple passes instead.<\/li>    <li><strong>Avoid mowing in extreme heat<\/strong>: Using your mower in high ambient temperatures can overheat batteries and cause permanent damage.<\/li>    <li><strong>Store properly in winter<\/strong>: Disconnect the battery and store it in a cool, dry indoor location, ideally between 50 F and 68 F. Lithium batteries should be stored with a 30%-50% charge; lead-acid batteries should be stored fully charged. Use a battery maintainer or trickle charger for continuous optimal charge.&nbsp;&nbsp;<\/li>    <li><strong>Never use the battery to jump-start a car<\/strong>: Lawn mower batteries aren&#8217;t designed for this, and warranties don&#8217;t cover such damage.<\/li> <\/ul>    <p><strong>See Related:<\/strong> <br>&#8212; <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-mow-tall-grass\/\">How to Mow Tall Grass In Your Lawn<\/a><\/p>    <h2 class=\"wp-block-heading\" id=\"8-lawn-mower-battery-lifespan-\"><strong>Lawn Mower Battery Lifespan<\/strong><\/h2>    <p>With proper maintenance, expect:<\/p>    <ul class=\"wp-block-list\"> <li><strong>Lead-acid batteries <\/strong>to last 3-4 years<\/li>    <li><strong>Lithium-ion batteries<\/strong> to last up to 5 years<\/li> <\/ul>    <p>Factors affecting lifespan include overcharging, extreme temperatures (hot or cold), and cleanliness.&nbsp;<\/p>    <p>&#8220;When (your battery) starts to wear out, the biggest thing you&#8217;ll see is it won&#8217;t last as long,&#8221; Koenig says.

Lithium-iron phosphate batteries (12V) cost $140-$200 each, and lead-acid batteries start around $65-$70 each, but with both types, you typically need 2-7, depending on the mower model. 48V LiFePO<sub>4<\/sub> batteries are available, but cost upward of $600 (bypassing the need to buy multiple).<\/p> <\/div> <\/div>    <h2 class=\"wp-block-heading\" id=\"13-let-lawnstarter-handle-your-lawn-care-\"><strong>Let LawnStarter Handle Your Lawn Care<\/strong><\/h2>    <p>If battery maintenance and mower upkeep feel overwhelming, <a href=\"https:\/\/www.lawnstarter.com\/\"><\/a>LawnStarter connects you with <a href=\"https:\/\/signup-web.lawnstarter.com\/cart\/contact-info?intent=mowing\">local lawn care professionals<\/a> who bring their own reliable equipment to every job.
