Battery Tender Junior vs Battery Tender Plus vs Battery Tender 800

Battery tenders are commonly found in many vehicles such as motorcycles and ATVs, which most people prefer using for fun, especially at weekends. There is a way of keeping the motorcycle charged before riding. The battery tender chargers are made to check the charging process and maintain the charge present in the battery.

The battery tender products are widely available in the market because of their benefits: they charge small vehicles such as ATVs faster, and they have a more extended warranty period, which is around five years, among others. The article below compares the three battery tenders present in the market, their advantages and cons.

Common features of Battery Tender Junior ,Battery Tender Plus ,Battery Tender 800Battery Tender Junior vs Tender Plus vs Tender 800

All the battery tender chargers perform the same function and have some common similarities since they manufacture them. Their similarities are as discussed below;

  • Safety systems

All three chargers have a safety mechanism that protects the batteries from charging issues. The charging issues include; power sparks, overcharging, overusing and reverse polarity. Reverse polarity is how a negative terminal of the charger is connected to the positive terminal of the battery and vice versa. Reverse polarity may damage the batteries being charged, increasing battery or charger replacement costs.

  • Supported batteries

All three battery tender chargers are designed to function the same on the same vehicle models: small motorcycles and ATVs. Also, the chargers support lead-acid batteries.

  • Methods of connection

Unlike other chargers that use crocodile clips, these chargers use alligator clips and a connection cable with some ring terminals to transmit power from the source to the batteries.

  • Charging program

All chargers have automated charging programs. Once the chargers are connected to the battery, they will always connect automatically. In terms of usage, they are easy to use since you connect and forget.

  • Built-in charging mechanism

The built-in charging mechanism protects the batteries from overcharging and maintains the charging level present in the batteries.

Key differencesKey differences

Despite all the three chargers being similar, they have differences, especially in terms of the price.

  • Design and appearance

The three batteries are almost the same size. They are all small hence compatible, and they have a slight difference that is not easily recognized. Their small light and less weight makes them more consistent and portable, especially when travelling for some distances. Despite having the same size, the size increases depending on the rise in output power.

Battery tender 800 differs slightly from the other two chargers since it has a waterproof mechanism that protects the charger from water issues. Such a feature makes it more applicable in fields such as water sports, among others.

  • Performance

Each charger charges batteries at different rates. The battery tender plus model has larger current output compared to others. The output is 1.25 amperes that charge the battery faster within a short time, approximately sixteen hours for a 15-ampere battery.

Therefore, if you choose a charger that can charge your battery faster, consider using the battery tender plus charger model.  Finally, use a charger that suits the battery amperes to avoid damaging the battery.

  • Supported vehicles

Despite all the chargers performing the same function of charging small vehicles such as ATVs and motorcycles, they generate different outputs. The battery tender plus produces 1.25 amperes output, indicating that it can charge batteries faster than the others.

For battery tender junior, it produces 750-ampere output, which is almost the same as the battery tender 800. The battery tender 800 generates an output of 800 mA. All batteries are designed to charge only small motorcycles and not car batteries because they don’t support batteries with high voltage; instead, they only maintain them when fully charged. To use the chargers, connect a fully charged battery, and it will automatically maintain the level of battery charge optimum.

  • Cost

Each charger has different prices. The battery tender junior costs less compared to the other two chargers. It costs around $30, and it has a more extended warranty, around five years. The cost is friendly. The battery tender plus has more advanced features making it more expensive than others, and it costs around $100. Also, it has a more extended warranty period than junior, a ten-year warranty that makes it suitable for larger ATVs and motorcycles.

For the battery tender 800, it is much more expensive than the junior battery tender. Due to its waterproof feature costs around $60 and the warranty is up to 3 years. The waterproof feature makes it suitable for marine boats.

Battery tender 800

Such battery chargers are efficient for waterproof vehicles such as marine boats and are used for sports activities.

  • It has a waterproof mechanism making it suitable for marine boats and jet skis.
  • Small in size hence easily portable and compatible.
  • Charges many small vehicle batteries, including lead-acid batteries.
  • Has an automatic charging system with four stages.
  • It is the most expensive, costing $ 60, which is twice the junior battery tender.
  • Has reduced warranty period of approximately three years, unlike battery tender

The waterproof feature makes it applicable in marine boating where there are charging issue risks, especially with chargers that lack waterproof quality. Therefore, it is advisable to consider using the battery tender 800 instead of the other two for marine activities.

Battery tender junior

Most people prefer using the battery because it is much cheaper than the others. This type of charger only maintains larger batteries at the optimum level. Also, the charger reduces the costs of buying an extra permanent attachment terminal harness.

  • The price is lower and affordable.
  • It is small in size hence portable and compatible, just like the other two battery tenders.
  • Maintains the battery charge present at optimum level without damaging the battery.
  • Comes with easy connecting cables.
  • Charges slow since it has a power output of 800 mA.
  • Lacks a waterproof mechanism hence not suitable for marine boats and jet skis.
  • Charges smaller vehicles such as small ATVs.

The battery tender is suitable for charging smaller vehicles that have small battery capacity. The most preferred owners to buy such types of battery tender are scooters and small-engine cars.

Battery tender plus

The battery tender is of high quality hence more expensive than the other battery tenders.

  • Has high quality.
  • More extended warranty period, approximately ten years.
  • It withstands larger amperes hence faster charging.
  • Maintains optimum charging level.
  • Comes with accessories such as crocodile clips and a quick connector.

  • Expensive.
  • Larger in size than the other chargers.
  • Lacks waterproof mechanism hence unsuitable for marine boats and jet skis.

The battery charger is suitable for large vehicles with large battery capacities and larger engines such as large ATVs and large motorcycles. Also, it is ideal for people who wish to charge their batteries within a short time.

Frequently asked questions:

  • Can I use my battery tender charger to charge the car battery?

The answer is no. The three battery tender charger models have a low power output that does not support car batteries, and the chargers will fail to transmit power from the source to the car batteries to start the engine. Despite them failing to charge the car batteries, they can only maintain them when fully charged to prevent the batteries from overcharging.  Therefore, it is advisable not to use the battery tenders for car batteries to avoid damaging the charger.

  • What is the function of the quick connector?

The connector allows the battery and the charger to connect easily.


Each battery tender has unique features that uniquely identifies it. For instance, the 800 model has a waterproof feature, and the plus model is high quality. To choose the best battery tender charger for your small vehicles and motorcycles, read the review above and pick the best charger that suits your battery model.

Finally, maintain and take care of the battery tender charger to increase its lifespan. Also, avoid using the wrong battery tender charger for the different batteries and also for car batteries.
