Almost a necessity

These things really are darn near a necessity when it comes to maximizing the life of a battery. Even more so when the battery is used seasonally. I have never had any problems with them.

Q: What would happen if I used the regular Battery tender jr charger on a Lithium battery?

A: Note: The use of a lithium-specific charger such as the units in the Battery Tender(r) Lithium Charger series is strongly recommended.

Note: It is highly recommended that a charger specifically designed for charging and maintaining lithium-ion batteries be used with this battery. Standard trickle chargers with a desulfation circuit should NOT be used.
These have been taken from two different manufacturer's the Top one is from Battery Tender themselves, my recommendation is to use the proper tool for the job always.

Q: Will this charger work with a VRLA (valve regulated lead acid) battery?

A: To answer my own question: Yes this tender jr is working fine with my VRLA battery. The battery in question is a GT4L-BS (VRLA) battery that came with my new 2017 Yamaha TT-R125LE. What prompt me to ask was the notice in the owners manual which reads -

" To charge a VRLA ( Valve Regulated Lead Acid ) battery, a special ( constant-voltage) battery charger is required. Using a conventional battery charger will damage the battery,"

So far tender jr went from red light (charging) to blinking green (80%) to solid green (storage mode).

A: For a Lithium battery you would want the Battery Tender Waterproof 800 High Efficiency Lithium Battery Charger. Designed for charging and maintaining all Lithium Power Sports Batteries. The California Energy Commission (CEC) compliant high efficiency 12v charger provides the correct lithium specific 5-step charging sequence ensuring peak performance from your Li battery.

A: The Battery Tender Jr. we sell would be set up for 2 pin American style plugs (120 VAC Input Voltage, 60 Hz Frequency). You may want to contact Battery Tender directly to see if they would make a Battery Tender Jr that would work with UK Plugs. http://batterytender.com/contact_us/

Q: Can I use it to charge a new BMW GS 1200 while the battery is still connected to the bike? Won't it interfere with the bike electronics?

A: Yes, you can use this while the battery is installed in the bike. I do this with my personal bike actually. Included with the battery tender is a quick disconnect cord that can be hooked up to the battery and left on the bike. This feature makes things very simple for bikes that have hard to reach batteries and it will not effect the electronics on your motorcycle. Once the battery reaches full charge the battery tender will go into a storage mode that will just maintain the batteries charge without overcharging.

A: No worries there you will like how it will prolong the life of you battery. the one thing all motorcyclist hate to replace time after time. It will be worth every penny of savings of battery replacements in the long run.
