Battery Tender 021-0123 Battery Tender Junior 12V Battery Charger

I find that the Battery Tender Jr battery charger is a bit different from a trickle charger with its microprocessor controlled power electronic circuitry. For starters, it is manufactured by Deltran. They were founded in 1961and maintain a high standard of excellence, being the official authorized manufacturer of these battery charger brands – Harley-Davidson, Lotus, BMW, Mini and others.

When putting this charger to the test, I found that the charger performs a number of advanced charging functions which are beyond the capabilities of a trickle charger. When you look at price, which is always important, I found that while trickle chargers appear to be a better choice, they don’t have the advantages of electronic control. The Battery Tender Junior battery charger, going at a price below $40, has microprocessor controlled power electronic circuitry. This is what enables it to perform a number of sophisticated charging functions with minimal output current amplitude.

Always Ready to Go

When I connect the Battery Tender Jr to a battery and apply AC power, it conducts checks during its Initialization Mode. This ensures the battery is functioning normally and before it delivers its full charge at a constant rate of 0.75 amperes. The battery voltage rises, and upon reaching a predetermined level, the charger or maintainer holds the battery charge voltage constant, allowing the charge current amplitude to drop. This is known as the Absorption Charge Mode.

After the current drops, the Battery Tender JR automatically switches to a Maintenance Charge Mode so as to maintain the battery voltage above where it would be if it were fully charged. This ensures the battery is topped off at voltages below the gassing voltage of a lead acid battery.
If you are looking for a reliable battery tender/maintainer for your classic car, your boat or motorcycle for instance, the Battery Tender JR is your best bet. The charger will keep the battery fully charged so that it is always ready to go. It will likely cost a bit more than a trickle charger but then it has performance improvements built into

Features of the Battery Tender Jr:

●comes with a 5 year limited warranty
●12 volts
●amperage – 0.75 A
●lightweight, compact size – ideal for those hard-to-fit spots
●easy to use in small spaces
●guarantees batteries are maintained after charging and ready to go
●spark proof
●12 ft output cord

●solid state 2-colour LED indicates the stage of charger – is something goes wrong, the Battery Tender Jr is spark proof, providing reverse polarity protection.
●ideal for all lead-acid, sealed maintenance free batteries or flooded batteries
●4-stepcharging program – Initialization, Absorption Mode, Float Mode, Bulk Charge
●automatically switches to maintenance voltage after fully charging the battery
when the battery voltage drops too far under load, full charger output power starts
●reverse polarity protected.

What’s In your Battery Tender JR Package?

●Fused Alligator clips
●Fused Ring Terminal Harness for those difficult-to-reach spaces

Just like me, I find that people like the Battery Tender JR charger as they simply don’t want a charger where you have to take heaps of steps to monitor the charging process. Battery Tender Jr is fully automatic and all that is required is that you connect it and forget it.

People appreciate this charger. I have friends who are in the electronic field and who have tried and tested this charger along with other similar chargers. They tell me that that the Battery Tender JT does all it claims to do and more, switching from charge to float charge exactly as it claims.
Pros: 

• good, reasonable price
• very compact and portable
• easy to use
• batteries charged in 8 to 10 hours
• excellent shipping – product came well packaged.

Cons:

When you read reviews from customers, most say there is nothing really worth mentioning as a disadvantage of this versatile product.

What More Could You be Wanting?

Deltran brings you the best in 12 volt lead acid battery chargers, offering advanced technology which makes the charge perfect for charging a host of lead acid battery applications. Offering different power levels as well as a factory warranty, the Battery Tender JR is designed to fully charge and maintain batteries in such as way as to avoid the damaging effects caused by most trickle chargers.

Fully automatic, equipped with a variety of safety and interconnect options which you don’t find on many other models, zero to minimal current draw from batteries, full output power at low AC line conditions, visual indication of charge state and a compact, lightweight charger – the question is – what more could you be wanting?
