I have a battery tender PLUS and it has kept the original battery strong on a Yamaha Roadstar for 4 1/2 yrs. I sold it this summer (still with the original battery) and bought an 07 KLR

I use the Battery Companion by Schumacher. I paid about $18 for it at Wal-Mart. It has the float-mode for monitoring. It the battery drops it kicks in til its topped up again. No need of worry about overcharging. In fact I have two of them. One for the boat battery and one for the KLR.

I have the - available everywhere - Battery Tender Jr. by Deltran. Works fine. It will keep a battery at the same level, but it does not 'charge' a dead or low battery. If you have a half charged battery and plug it in; Six months later - you'll still have a half charged battery. FYI.... Most bat tenders only keep a battery at the same level, they don't charge up any more than the battery's current state.

The Tender Plus model I have has a slow charging cycle, then it goes into a maintance mode, It kept my battery at full charge through 4 winters.

Just to clarify, this model does "charge". I have used it on marine batteries that had been sitting for 3 to 4 months without being charged. The "tender" only charges at a rate of 1.5 amps and it took about 16 hours to peak the battery. Then it goes into a "float mode". I can run electronics such as a depth finder or a bilge pump for a few seconds just to test the "tender" and the green charged light goes out and the yellow charging light comes on as it again peaks the battery to top charge. So it does charge but isn't designed to charge large batteries from "dead" although it would after a few days I suppose. Make sure that the unit you purchase says "charger/maintainer" and you should be fine.

I have the Battery Tender Plus... Works great... I bought additional connectors and have them on my 4-wheeler, tractor, ect. It works great and is easy to use.

I have to differ with your description........the BT Jr. WILL charge a battery, albeit, slowly. This from the MAW Online site:

Battery Tender Junior
Full automatic two-stage lead acid battery charger. Lightweight, compact size. Trickle charger with a brain assures batteries are maintained after charging. Ideal for all lead-acid, sealed maintenance free and gel cell batteries. After full 14.4 VDC charge is reached, converts to float charger and moniters battery at 13.2 volts. When voltage drops below 12.6 VDC, charger resumes charging back to 14.4 VDC. Two-color LED indicator. Spark-proof; reverse polarity protected. 12' output cord and quick-connect harness. Battery Tender(R) Jr. comes with a set of quick disconnect clamps and rings.

The BT's will also charge the AGM (glass matt) and sealed batteries, no probs.
I have the BT Plus ($37.95 at MAW, http://www.mawonline.com/batteryt.htm ), in fact, I have two of them.......one is in my garage on my 1800VTX and the other is on the KLR in my shop. The VTX battery is now 4 yrs. old and working fine. BTW, I also use the one in the shop on my lawn tractor battery...it DOES charge it. At 1.25 amp charging rate, it takes a long time to charge a really low battery, but, it won't boil one dry like a heavier charger that is not automatic.

Roland: Thanks for the info. Maybe that's how they are supposed to work, but mine however; does not. Maybe mine is defective. But it does what I paid it to do, and that is, to keep the batteries alive. I have a charger for charging, and a tender for saving them while not in use.
