Frequently Asked Questions about battery tender 4 amp lead acid & lithium selectable battery charger
At 4 AMPs, this battery charger offers a quick recharge on automotive, marine, and powersport batteries. An ideal charger for everyday charging use or long-term storage and maintenance, it is compatible with 6 volt and 12 volt lithium, AGM, flooded, and gel batteries.
So you just pull those two apart and it comes with two different setups. One of these you can wire. Into your battery terminal posts. So you just take that off and these are looped.
about 10-24 hours
Charging a regular car battery with a typical charge amp of around 4-8 amperes will take about 10-24 hours to charge it fully. To boost your battery enough to be able to start the engine, it would take around 2-4 hours. The best way to maintain a long life for your car battery is by recharging it slowly.
A lead-acid battery charger does everything you might expect, charging lead-acid batteries in a unique and effective way that will have smaller batteries ready to go in 5 hours and larger ones fully charged in 12 hours. Lead-acid batteries use a method of charging called 'constant current constant voltage' (CCCV).
To be safe, assume that the batteries require a full 100% charge after the cells are filled. For example, a 16 Ah battery will take about 13 hours to get to the absorption voltage (constant 14.4 Volts). It may take another 6 to 8 hours to reach the float voltage (constant 13.2 Volts).
Most phones and other devices are capable of handling 5V/2.4A. For fast charging, manufacturers bump the voltage up from 5V to 9V or 12V and beyond, or increase amperage to 3A and above.
A 'fairly' dead battery should charge up in about 24 - 36 hours. If the battery has access ports, you might want to check the water level (DISTILLED water only). If it is low in any of the chambers, then you would fill that chamber with distilled water up to the bottom of a concave meniscus level at the markers.
It's just a specialized charger which will help keep the battery in tip-top shape while a car sits. The normal lifespan of a regular battery is around 5 years. While a maintainer (or tender, if you like) won't extend the life of the battery, it should allow you to get the full lifespan of the battery.
20 hours
A 4Ah battery with a capacity of 4000mAh can last for 20 hours if it is discharged at a constant current of 200mAh, and it can last for 8 hours if it is discharged at a constant current of 500mAh.
Charge 4 and Charge 5 have a battery life of up to 4 days. If you use built-in GPS continuously, Charge 4 and Charge 5 have a battery life of up to 5 hours, Ionic has a battery life of up to 10 hours.
When, at a charge voltage of 2.45 ± 0.05 volts/cell, the current accepted by the battery drops to less than 0.01 x C amps (1% of rated capacity), the battery is fully charged and the charger should be disconnected or switched to a float voltage of 2.25 to 2.30 volts/cell.
To check the voltage you'll need a voltmeter, which can be purchased cheaply from most major automotive parts stores. Check the voltage of your battery using the voltmeter to help determine your next course of action. 12.6V volts or above - Your battery is healthy and fully charged.
The Battery Tender® Junior charges at a rate of 750mA, or 0.75A per hour. Therefore, a fully discharged 15 Amp-Hour battery will take approximately 16 hours to recharge to 80% capacity.
Ans: Yes, battery tenders can be used to charge dead batteries, however, this process may take longer than using traditional chargers. As battery tenders are intended to maintain battery charge levels without overcharging, their charging power may differ significantly from traditional chargers.
So, for a 3000mAh battery, we would want to charge at 3A, for a 5000mAh LiPo, we should set the charger at 5A, and for a 4500mAh pack, 4.5A is the correct charge rate. The safest charge rate for most LiPo batteries is 1C, or 1 x capacity of battery in Amps.
Fast charging reduces the lifespan because it produces more heat. But again, if it's convenient for you, just leave it on. Sure, you might need a battery replacement sooner, but you would've needed that replacement anyway.
