Great Product
This product works just as described and is working perfectly. The only thing that surprised me was that it took a couple of days for the tender to completely charge the system before the light turned green. Of course, this was on my dodge diesel truck that has two batteries. Everything is now working as it should.
I am really happy with the Tender Plus.

Worry free battery maintainer
The battery tender just works. It completes the whole charge cycle and finishes in a “storage maintenance state”. With the recent stay home orders, I use the charger on both cars to keep the batteries up with the infrequent vehicle usage. Newer cars tend to deplete the battery quicker with all the on board electronics and computers. So if the vehicle sits for a while, the battery will be discharged and eventually ruined. The battery tender is a 1.25 amp model so it takes about a day to fully charge a 60A/hr 450CCA car battery from a 75% charge. Over all a great product. This product is mainly a maintainer, so if you need a fast “jump charge” a higher amperage model would be more suitable.
BatteryStuff processed my order quickly and I had the unit in a few days. Order process was easy and no problems with the website.

Outstanding
The Battery Tender Plus 12v 1.25 Amp 4 Stage Smart Charger is outstanding. I have 3 of them and just purchased 2 more. They will not let you down. The 3 that I have are almost 10 years old and still work great. The price is very good and the customer service I received from batterystuff.com was ourstanding.

Excellent
I bought this tender in 2012 as I travel frequently on business and my vehicles sit for weeks at a time. I have used this on my BMW motorcycle AGM battery, My Ford F-150 AGM battery and a conventional (flooded) battery in my older Chevy. Had zero issues or complaints and I get 7-8 years out of automotive batteries by using this tender as needed.
