5Battery Tender-I must have 10 or more
I have many different vehicles and pieces of motorized equipment. Everything from a 50 ft long motor home with 4 engine starting batteries, to four Harley Davidson motorcycles. The common thread is that they all sit for extended periods of time, and they all have expensive batteries. I have tried all of the different battery maintainers I could find and I still keep coming back to Battery Tender. Aside from the terrific reliability, (not true for other maintainers), the best feature for me is the fact that all you do is plug the Battery Tender in and forget about it. Everything is automatic....this is important if the power fails. Other Battery Maintainers require that one push buttons to set certain parameters. The unfortunate side effect is that the charger will not work without the afore mentioned "button pushing" and your battery may be dead when you need it. Stick with Battery Tender!

5Battery Tender Plus
By E. C. Herron
Battery Tender Plus 022-0157-1 received as described. It is a compact size in a heavy duty, weatherproof case which makes it great for outdoor applications such as charging batteries on a travel trailer. Very easy to use...just plug it in and walk away. Consider getting extra wiring harnesses for other charging applications. Harnesses make it easy to plug in and charge batteries without having to hook up bulky clamps and cables. Would recommend.

5Save your battery
By Donald Filbert
This is a great product for protecting your batteries. I have used it for years on my TransAm, which I rarely drive, and my motorcycle. Motorcycle batteries usually last 4 - 6 years. My last one lasted 9 years. I have a friend who has a Z which he rarely drives; and during the time I had one battery on my TransAm - he replaced his 3 times. After suggesting he get one of these 3 or 4 times with no success - I finally bought him one myself.
