Perfect for all lead-acid, flooded or sealed maintenance free batteries (AGM and gel cell). Complete 4-step charging program (Initialization, Bulk Charge, Absorption Mode, Float Mode). Automatically switches to float / maintenance voltage after fully charging the battery.

Description. The Battery Tender® Junior 800 is the perfect versatile charger for lithium or lead-acid batteries in your motorcycle or other powersports vehicle. This 12V, 800mA charger can extend your battery's lifetime and can switch between charging AGM, lead-acid, GEL, flooded, and lithium (LifePO4) batteries.

Can a Battery Tender Ruin My Battery? Proper use of a Battery Tender should not damage a battery's lifespan if used appropriately. Using it correctly can extend its lifespan by helping keep its charge steady and avoiding overcharging or undercharging issues.

The red light will remain on until the charger completes the charging stage. < GREEN LIGHT FLASHING –When the green light is flashing, and. the red light is on, the battery is greater than 80% charged and may be removed from the charger and used if necessary.

AGM batteries recharge faster than regular batteries. Fiberglass mesh mats soaked in electrolyte carry current faster than liquid electrolyte. Yes, that's how AGM batteries can deliver big bursts of power even if they're drained. It's also how AGM batteries recharge faster than regular batteries.

An AGM battery can save you time and money They last longer than regular batteries. Because they don't have any liquid inside them, AGM batteries have fewer components to fail, so they last longer than traditional car batteries. They're more efficient than regular car batteries.

This. One actually has twice the capacity of a standard battery. And it's meant for vehicles. That. Need higher power requirements.

Despite its overall advantages, lithium-ion has its drawbacks. It is fragile and requires a protection circuit to maintain safe operation. Built into each pack, the protection circuit limits the peak voltage of each cell during charge and prevents the cell voltage from dropping too low on discharge.

Battery Tender is a brand of products for maintaining a car battery's charge, generically known as trickle chargers. A trickle charger delivers a slow and steady energy stream to maintain a car battery's charge during storage. Maintaining a charge helps prevent damage caused by depleting a car battery.

Battery maintainers are designed for constant and long-term use. When used correctly, they should be perfectly safe to use as long as you need. It's not a bad idea to check the maintainer every once in a while. While it shouldn't cause any harm to your batteries, it could short out at some point.

When the light is flashing green, your battery is at least 80% charged and a solid green light informs you that your battery is maintaining an optimal charge. Connect and forget with the Battery Tender® Junior!

The green light continues to flash for 8 hours or until the battery is fully charged. Then the green stays on and the red light turns off. 5. RED & GREEN ALTERNATING LIGHTS: When the red and green lights alternate, then either the 72- Hour Safety Timer has been activated or the battery is defective.
