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.

In simple terms, a 5A charger will charge your battery faster. The 5 amp (A) charger allows more current to pass to charge the battery. The 2A-48V and 5A chargers are compatible with the S-series and R-series vehicles.

In a nutshell, a battery maintainer is used to keep a battery charged over a long period of time. A battery charger is used to charge a dead or completely discharged battery. A battery charger uses high current, whereas a battery maintainer uses low current to charge and maintain the battery.

The higher the number, the faster they will recharge. A 5 amp charger will re-charge mid-range batteries fully in 10-12 hours and should be fine for most fishermen.

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.

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.

Please be kindly informed that the total wattage of the devices(LED strip lights) should not exceed the max wattage(25W) of this adapter(5V 5A).

The GENIUS5 is a 5-amp (75-watt) - 100-240VAC 50-60Hz - 6-volt and 12-volt heavy-duty battery charger, battery maintainer, trickle charger, float charger, and battery desulfator for up to 120 amp-hours.

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.

A charger with 15 amps, for instance, will take about two hours to fully charge a battery at a 25-percent discharge value. Chargers with only 5 amps, however, will need a full six hours with the same battery.

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.

About 10-24 hours, depending on how weak your battery is. If you're using a trickle charger, expect it to take days. Don't expect an under-charged battery to do the job of a fully charged one. Take your battery off the charger early, and you may risk needing a jump-start later.

In theory, you can leave the Battery Tender® Plus battery charger connected to a battery forever. That's a really long time. Sales people like to say, “Just plug it in and forget about it!” However, practically speaking, it is a good idea to check on the battery at least once every couple of weeks.
