what brand of battery tender do you recommend?

The car came from the factory with one - is it now lost ? Maybe check with the vendor else there's been a few tender threads in the past for you to look at

 

Battery tender: CTEK 7002 https://www.amazon.com/CTEK-56-353-12-Volt-Battery-Charger/dp/B000FRLO9Y/ref=sr_1_5?crid=12L1Q97YCLE22&keywords=ctek+7002&qid=1671214566&sprefix=ctek+7002%2Caps%2C194&sr=8-5&ufe=app_do%3Aamzn1.fos.f5122f16-c3e8-4386-bf32-63e904010ad0 (I have one on all my cars, including my 458 and Portofino M)

The CTEK MXS5 is the way to go.

CTEK and CTEK Lithium

 

If over the long run performance means anything to anyone.....then, The Deltran "Battery Tender" is the way to go, period. I have ran these now for 15-20 years and they do not let you down. Each battery (Ferrari excluded so far) has lasted somewhere around 12 years or more without fail. Caveat, just be sure you never drop one or allow it to be constricted for whatever reason and its good to go ! I am hoping that my more Ctek inspired one in my SpecialeA is up to that task, we'll see. I would have to think that they would work for your application.

 

If your car came with a lithium ion battery, you MUST use a tender specific to lithium ion batteries, or at least one with a lithium ion mode. I have a CTEK 56-926.
