Battery Tender® Junior vs. Battery Tender® Plus vs. Battery Tender® 800: Which battery charger do you need?

Motorcycles and ATVs are often only used for short periods, and inevitably, they stand in the garage idle for long periods. In most cases, they are for weekend fun, while during the week you use your car. A lack of use is a big issue for a battery, and it got me wondering the best way to keep a motorcycle battery charged.

In just a few minutes of searching, I found some great solutions, such as the Battery Tender® range of battery maintainers. These sophisticated devices monitor the battery charge and automatically maintain your battery at the optimum voltage.

This brief article compares three Battery Tender products aimed at the smaller end of the market.

Battery Tender Junior vs. Plus vs. WP 800: What Are The Similarities

Charging time

With a much larger output of 1,25 amps, the Plus model will recharge your battery significantly more quickly. For example, a fifteen amp battery will take ten hours with the plus, but the Junior model will need sixteen hours.

If quicker charging is your priority, then choose the Plus model.

Design

The three battery chargers and maintainers are small and compact, only increasing in size a little as the power output increases. The compact size makes them easy to carry with you, in your pocket or motorcycle luggage, for example. Going away on a trip doesn’t mean you can’t take a battery charger with these small Battery Tender® models.

The Battery Tender® WP 800 has a significant advantage over the other two, though, as it is completely waterproof, making it ideal for water sports uses.

Supported vehicles models/makes

Although all the chargers are aimed at the small vehicle market, such as motorcycles and ATVs, the power output distinguishes them from one another.

The Battery Tender® Junior and WP 800 have almost identical outputs at 750 and 800 mA, respectively. However, the Battery Tender® Plus gives a significant jump to 1.25 Amps, which means it will charge batteries more quickly.

Although none of the Battery Tender® on the review are designed to charge car batteries, they can be used to maintain them. Connect a fully charged car battery to one of these models, and it will automatically keep your car battery at the optimum level.

Price, warranty

The Battery Tender® Junior model is the cheapest on the review, at around $30, and is good value for owners of smaller machines. It comes with a 5-year warranty, which is quite generous.

At the other end is the Plus model, which offers a much greater power output, but at three times the price, being around $100. However, you also get a ten-year warranty with this model, so it may be worth it for owners of larger motorcycles and ATVs.

The waterproof 800 model is double the price of the Junior, and its warranty is reduced to just three years. However, owners of boats may consider the higher price worth it for the waterproofing, despite the reduced warranty period.

The Battery Tender is designed for boats and jet skis, so is it waterproof?

Only the Battery Tender® WP 800 is fully waterproof.  While the other models may be drip-proof, they are not designed to be used near large amounts of water.

Are smaller Battery Tender® models suitable for charging car batteries?

No, the three models in this review are not suitable for charging car batteries. This is because the power output they provide is too low for larger batteries, and the charging time would be unacceptable. However, all three models on review can be used to maintain car batteries in optimum condition once fully charged.

What is the quick connector designed for?

The quick connector cable remains attached to the battery at all times and allows you to connect your Battery Tender® easily. It is handy when the battery is in a difficult-to-access location.

Do these charge my battery automatically?

Yes, once connected, the Battery Tender® charger all switch into automatic mode. This is a 4-step process that checks the battery charge, bulk charges and then uses absorption mode to complete the charging. Once fully charged, the Battery Tender® will maintain the correct voltage as long as it is connected.
