Part No. 021-0123

We're Sorry...We do not currently have vehicle fitment information for this part but are working on it.

product description
The 12V Battery Tender Junior is a trickle charger, and more. It is compact and lightweight in design, and fully automatic, with a complete 3-step charging program (Initialization, Bulk Charge, Float Mode), and automatically switches to float / maintenance voltage after the battery is fully charged. It's easy to use, and works great in small spaces. The 12V Battery Tender Junior is perfect for all lead-acid, flooded or sealed maintenance free batteries (AGM and gel cell). It will keep your battery fully charged so that it is always ready to go.

We have not yet cataloged this product for vehicle specific applications and therefore cannot assume responsibility for fitment. Please read the description carefully and confirm via the manufacturer before placing order, or call one of our technicians at 1-877-787-8989 for assistance. Returns due to mis-ordering must be returned freight prepaid and may be subject to a restocking fee.
