User Reviews about Battery Tender 021-0128 Battery Tender Plus 12V Battery Charger

It's a great little device. It charged my completely dead battery in less than two days. After that, I kept it on. It won't harm the battery. It has been working fine since then.
It's easy to use and hook up. -- Battery Tender

I have a '01 Yamaha FZ1 with a 10 year old Battery Tender attached to it for at least 6 months of the year. The Yamaha/Yuasa sealed battery is still the original factory unit, to my dismay (I grew up with wet 6V Yuasas on the 70's). Battery is going on 10 years but starts strong and holds charge without a problem... it is hard to believe.

This would NEVER occur before I started using this thing - any bike would have a weak battery within 4-5 years of installation if the bike saw no action for a good part of the year.

I also have a Ford Powerstroke Diesel truck (don't ask) with its two batteries that sees very little use during winter and sits outside and exposed. I have a Battery Tender attached to it and the truck starts strong. This was not the case before I replaced the batteries and installed a second Battery Tender for it.

Last but not lease if you go to any BMW dealer you will see BMW re-badges Battery Tenders and sells them as a BMW accessory to help keep their electronic-heavy models from dying in the garage when they are not used often enough... -- Just plain works

I ride a Goldwing Trike and I have had a battery tender for years. Nothing else lets me keep the battery in the bike in the winter without the cold damaging the battery. I have found that it extends the life of the battery by as much as 2 years. Amazon had the best price and the service and delivery were excellent. -- Battery Tender

This is the first time I have purchased a battery tender.
It has worked great for my auto battery.
The size of the tender is perfect. It has kept the battery charged ever since, especially since the battery sits.
Highly recommend it to everyone. Fast delivery service from Amazon and it was in stock. -- GREATEST BATTERY PRODUCT

This product works EXACTLY as advertised. Easy to install and "idiot prof." If you leave you vehicle parked for extended periods of time, you need a Battery Tender. (No I don't work for the company.) -- Great product
