Frequently Asked Questions about battery tender junior 8v 1.25 amp battery charger
The Battery Tender Junior is a straightforward and easy-to-use battery charger and maintainer. It can be plugged into any wall outlet and is designed to charge most types of batteries. It has four modes or objectives; Initialization, Bulk Charge, Absorption, and Flat mode.
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.
The Battery Tender® Junior is an automatic battery charger, equipped with a Smart Microcontroller that functions as its “brain” to ensure the proper level of power is sent to the battery at all times.
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.

The Jr. s have a smaller charge rate but the same float rate as the regular battery tenders. The Jr. s keep the cars fully charged even though they have electronics that pull on the batteries.
A 1.25 amp tender will only keep a fully charged battery from discharging, it doesn't have to power to charge a discharged battery. Use a battery charger and fully charge the battery, then use a tender.
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.
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.
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.
80 Ah / 1.25 A = 64 Hours, so a nearly constant 1.25 amp charger (that would be the Battery Tender® Plus) takes only 64 hours to return 80% of the charge to a 100 Ah battery that was fully discharged.
Yes, it is safe. A battery tender can detect how much charge it needs and will auto stop charging when fully charge.
As a rule of thumb your battery charger should be 10% - 20% of the Ah rating of the battery. E.g A 100Ah battery would require a 10 Amp charger as a minimum. To prevent overcharging, you should keep the charger size to within 30% of the total capacity.
The ampere-hour rating denotes the power and longevity of a battery. This rating also denotes the hours a battery would last without a recharge. The ampere-hour rating for larger batteries, such as car batteries, is generally a 20-hour rate. Most car batteries range between 40 and 65-ampere hours.
if the battery is not bad it will recharge it but it may take a long time at 1.25 amps. A car battery is about 500–600 amp hours.
80 Ah / 1.25 A = 64 Hours, so a nearly constant 1.25 amp charger (that would be the Battery Tender® Plus) takes only 64 hours to return 80% of the charge to a 100 Ah battery that was fully discharged.
