Default Old Battery Tender New Bike

I have a 2021 street bob that I am looking to get a battery tender for. A friend from work had an old one he was no longer using. Would this battery tender be compatible with my bike? Also any other battery tender options, it seems Harley battery tenders are backordered on their website. Below is a photo of the older battery tender:

Yes it will. My battery tender jr is about 13-14 years old and has worked on my 2002 Sporty, 2013 Street Glide, and my 2021 Street Glide.

Congrats on your first post to HDF, welcome to the forum. That one will work just fine, download the user manual from the internet so you know the functions of the blinking lights.

Ya don't need a HD brand battery Tender. ANY battery tender will work. It's about the voltage, not who's brand name is on it.

That's an adequate tender for your bike, and it's waterproof to boot. As long as your coworker no longer uses it, perhaps he will sell it to you for a reasonable price? I believe that model has been discontinued, but HD sold them for $49.95.

Depends on the type of battery you have. An older Tender may not be the best choice.
From a battery manufacturer:
You can use a lead-acid charger to charge lithium batteries as long as you can set the maximum voltage of the charger and as long as the charger does not have an automatic equalisation mode enabled.Most modern chargers will let you turn that feature off, and assuming it is turned off, the charger should be safe to use.

If you opt to use a lead-acid charger with the equalisation mode disabled to charge a lithium-ion battery, then you must disconnect the battery as soon as it is fully charged, to avoid damage to the battery.

The ideal option, however, is to use the correct charger type for the battery. There are multi-mode chargers that can be used to charge any kind of battery and that have features to protect the battery and prolong its life.
