How to charge your lawn mower battery

[@lindyjohnson2908]

I think it is safer if you plug it in AFTER you clip on the positive and negative clips onto the battery. Thank you for your review.

[@TSGEnt]

Good tip! That makes perfect sense. Thank you!

Love your videos....got a question....just bought a new craftsman t100 lawn tractor and I also bought a battery tender for the winter and I'm not sure how to tell what kind of battery I have...the battery tender is for led acid battery's...will it work?

[@TSGEnt]

Thanks. Glad you are a part of the TSG experience. I know my T1200 had a sealed led battery and all worked fine. There's only one way to find out.😉 I'm pretty sure your mower instructions will tell you what battery you have. The Battery may say right on it. Does it have a "Pb" on it? look at 12:25 on my video for an example.

Seems like a fun and informative channel. Definitely a new sub. . Thank you, btw. Peace, Eric

You are most welcome. Thank you!

Thanks Paul. Good review and info. Just wondering...do you know if the ‘recondition mode’ (or any other mode) on that B&D charger is the equivalent of what a ‘battery tender’ would presumably do for automobile batteries that are exposed to very cold weather for long periods during winter while simultaneously not being used to start & get recharged via alternator? I think battery tenders just release a trickle charge to maintain cold crank amps but they have to be connected full time to achieve that goal & wondering if the B&D model can serve that additional purpose as well.

[@TSGEnt]

You're welcome! The 'recondition mode' sends short reoccurring "shocks": to the battery that helps release the sulfate/electrolyte build-up on the battery plates. If a battery sits too long this build-up will occur (think corrosion on the plates) making the plate less effective at acid to metal reactions that are necessary to create electricity. If you put the charger into charge mode, when it senses the battery at full charge, it will go into "float" mode which is the 'battery tender' mode you are referring to. So yes the B&D does the trickle charge function to keep the battery filled at full capacity during times of non-use. They call it "float mode" (see 9:13)

[@kerryriggins3227]

Got it! Thanks for the explanation and confirmation.

@@joeseabert8391 Great. Glad to help.

[@sudburyhouse]

Did you know you can set the break on so you don’t have to be sitting in the seat for mower to start.

[@TSGEnt]

Affirmative. Thank you.

[@LatteBrown]

I had mine for over 5 years before I discovered that! Dah...🙃

[@sudburyhouse]

@@LatteBrown Yeah you can also set the break while you’re on it when it’s running if you want to get off the machine without it shutting down.

[@sophiasmith3524]

I sure wish I would've tried it your way first but I am just charging the battery cause I think it's pretty dead. I believe somebody left the key on 😢

[@TSGEnt]

Best to you. I hope you get it going.

[@pearlesme8561]

I just bought this & trying it in my mower!

[@TSGEnt]

I trust it works out for you. Let us know!

[@pearlesme8561]

@@TSGEnt it worked!

[@TSGEnt]

@@pearlesme8561 Awesome! 🙌

I bought a different charger and a separate battery jump starter. Is it fair to say that I could have just connected the charger i bought (while plugged in) to use as a battery jumpstarter? Or am I misunderstanding what you are using and doing in this video?

[@TSGEnt]

This device here does 3 things. Deep cycles a battery (drain then re-charge) float charge (keeps the battery topped off when not in use for long periods of time) and emergency (dead battery with no other battery to start a car, or in this case lawn mower). The device has a capacitor that delivers enough charge to start a motor. THe battery here was complete shot, so no assist was coming from the battery and the charger was trying to float charge as well as deliver enough amps to start the mower.

[@yahira2597]

@@TSGEnt Thank you for that information. I understand now.

[@katherineflanagan4027]

Paul you are to crazy. I have a portable battery charger and it had been charging for an hour. It acts like it wants to start but doesn't I didnt know the seat had to be down in order for the mower to start. I unpluged the battery cable to put the seat down and its completely dead. How long do I need to charge the battery.

[@TSGEnt]

It depends on how depleted the battery became. It could be beyond recharging. If the battery is still able to take a charge it could take a few hours in “charging” mode. Are using the charger depicted in the video? If so there is a start mode which provides the energy like a good battery to get it started then the motors regulator will charge the battery as you run the motor. Even so, if the health of the battery is poor, then even that wont get it charged.

[@Highvibes777]

How did you keep it going with seat up?

[@TSGEnt]

Break on and in neutral.

[@craigwagner327]

What is the point of boost charging to start it if your going to charge the battery for 24 hours anyhow? Couldnt you just charge the battery for 24 hours and not use the boost start? When charging what is the proper amp you should use when charging a lawn mower battery?

[@TSGEnt]

If the battery is not in optimum health, it may not have enough amperage to actually start the motor. The Boost gives it that extra help.

[@kathyhayes-bromley5199]

Well, that is awesome if your mower continues to run when you get off the seat, now what

[@TSGEnt]

as long as it's in neutral and brake is on, it's safe. After you get back on put her in gear and release the brake and away you go!

[@sudburyhouse]

🤣😂 the explosion was funny!!

[@TSGEnt]

Gotta have a little fun right?

[@GaryPierce73]

Very helpful and thank you! Love your personality! Will a 15 Amp charger damage my 12 volt mower battery? I've heard to only use a 10 Amp charger or less because anything above 10 may damage the battery.

[@TSGEnt]

What kind of battery is it? Always read the battery instructions. Depending on the battery, the more Amps the faster the charge. It's not the Amps that damage, it's the overcharging. If you are using a battery charger designed for your type of battery, it shouldn't overcharge. Most batteries like a charge 20% from full and don't like much lower depletion than 20% empty.

[@dorisb6364]

Wow get to the point man

[@nemonemo6285]

4 minutes 24 sec if you want to know about the battery charger!

[@TSGEnt]

But you'll miss the part with the cat.
