Keeps your battery in top shape without damaging it
Great charger. It monitors your battery and only charges it when required. No need to worry about over-charging or damaging your battery.

Battery Tender 800 Waterproof Charger. I was looking for an Li charger. Will this do?
A shopper on Oct 4, 2015
BEST ANSWER: The 800 Battery Tender has a lithium High Efficiency automatic input 12.0v & a out put 12v @800 mA
But to answer your Question you must check with your Battery 's owners Manual
* never use a desulfating type lead acid charger on a Lithium Battery
* never charge a battery that will not retain a charge
* if a battery gets hot while charging , Stop Charging & Discontinue Use .
* never jump start a Battery fro An Automobile.
For example my EarthX lithium Battery says to charge :
5A@15V(max) for 45min's
So bottom line is to read your owners Manual B-4 you Buy !!!
Is this dual voltage? Any Battery Tender dual voltage?
sebastian b on Mar 6, 2017
BEST ANSWER: No and there is no dual voltage.
Does this charger work on AGM batteries?
Chris D on Jun 25, 2016
BEST ANSWER: This battery tender, the Deltran Battery Tender 800 is designed for six cell lead-acid batteries, and would probably not be the choice for an AGM battery, however, Deltran has the Battery Tender 022-0186G-DL-WH Powr Tender Plus Battery Charger/Maintainer 12V@5A that will charge your AGM or lead acid, and designed to do so. If it is as good as the one I got from Revzilla, the Battery Tender 800mA, then it will do very well. I love my battery tender, bike is always ready to go, and we just had amazing rain here in N Central Texas, bike is stowed under a breathable cover, and the waterproof Tender just kept right on going. Love it and love REVZILLA, best place in the world to get your bike gear!!!
Do you have 220v ac input ?
