Battery Tender Costco, 4.5 Amp Smart Battery Charger


Costco sells this Battery Tender Charger & Maintainer for $42.99. Scroll down for photos. I had been looking for this for months & it finally was back in stock at Costco. These charger’s / maintainers are such a great tool to have around the house. I ‘ve seen these used on boats, motorhomes, RV’s, golf carts, Power Wheels & much more! The nice thing about this model is the 4.5 amps will give your battery a quick charge & then it will lower down to a “maintenance” stage to preserve the life of your battery. This chargers both 6V & 12V batteries as well as Lead Acid & Lithium Batteries. It’s a great tool to have in case you wake up to a dead battery. Here are a few more details about this Battery Tender from Costco……

Costco Battery Tender 4.5 Amp Smart Battery Charger & Maintainer


This is a tool I’ve always wanted to have in my garage. To be honest, the tipping point was that I will be buying my kid this Best Choice 12V Ride on Truck for Christmas. I dug deep into the reviews & long story short, the charger for this Power Wheels Truck is terrible. It ends up burning up the batteries rendering the toy useless. That’s where the Battery Tender comes into play. 2 new batteries (which doubles runtime of the toy) & an install of the included ring terminals solve the biggest issue with this toy. It’s also the safest / best way to charge the batteries. Now I’ve got myself a new tool & Power Wheels that will last years!
