If you were lucky enough to have a Power Wheels car as a child, or if you have bought one for your own children, then you might be perplexed to see this battery listed here. And it is true, this battery is intended as a replacement for Power Wheels’ brand of rideable, electric toy cars. But it just so happens that it makes an excellent gate opener battery too!

At first, it may seem that a toy car battery could be lacking in terms of the amount of power it can provide per charge. But, because a gate opener’s motor is in operation for a significantly shorter period of time each time it is used, this battery will be able to keep your opener in operation for an impressively long time. It is a 12 volt, 12 amp/hour battery, which will be suitable for a wide range of gate openers. And because it is intended for use with Power Wheels cars, it is rechargeable as well. Finally, this battery is available at a very reasonable price compared to many other options for your opener.

WHAT WE LIKE

Despite not being originally intended as a gate opener battery, Power Wheels’ 12 volt rechargeable battery is a high-quality, reliable product. It does not come with a charger for the battery, so you do need to provide your own (if you have a Power Wheels car, then this will be no problem!), but otherwise will come ready to use. Using solar power to power the battery is one popular option. Overall, this battery is an affordable, high-quality option that should provide you with reliable, long-term power for your gate opener.

PROS

  • Affordable
  • Durable
  • Compatible with many openers

CONS

  • Warranty could be longer
  • Does not include a charger

This Mighty Max battery is another solid option for your gate opener. It is a 12 volt, nine amp/hour battery, which is enough to power most gate openers. Of course, it is always a good idea to check the requirements of your opener before you purchase a battery. One of the most attractive features of this battery is its price, which is low enough that you could purchase several of these for the price of just one competing battery.

While there is the possibility of running into longevity issues when compared to significantly more expensive options, these batteries provide surprisingly impressive results for their price. The build quality is sturdy, as they are specifically designed to be mounted in any position without any leakage or increased risk of failure. If you want to save money on a battery, you may have a difficult time finding a better deal than this.

WHAT WE LIKE

This Mighty Max battery is not the most premium battery on the market today, but its ratio of quality to price is extremely high. The battery is well-made, reliable, and available at a small fraction of the price of some other batteries. For the money, this battery is definitely worth picking up. Its leak-proof design affords some peace of mind as well. You will never have to worry about dangerous acid leaks..

PROS

  • Very affordable
  • Leak proof design
  • Compatible with most gate openers

CONS

  • Some reports of charging issues
  • No charger provided
  • Some reports of failure after months or years of use

This Renology battery diverges from the previous two products. It is a more premium battery, which, while it carries a higher price tag, is designed with more heavy duty use in mind. One of the ways this battery offers greater versatility is by packing more power. At 12 volts and 100 amp/hour, this battery can hold and discharge significantly more power than either of the previous two.

This means you will be able to let your battery go much longer without requiring recharging, which will generally result in a longer-lasting battery. In addition to power capacity, this battery also has a very low self-discharge rate, meaning the battery will do a good job of retaining its stored power when not in use.

This is a useful feature for operating gate openers due to the intermittent nature of their use. The thoughtful design of this battery will come at a bit of a premium, but, depending on your needs, it can be well worth it. 

WHAT WE LIKE

If you are looking for a high-quality battery or you need more power than the first two entries on this list can provide, then this Renology battery might be the perfect fit. One thing to keep in mind about this battery is that it is quite heavy, at over 60 pounds, and that it is designed primarily to be mounted upright. But if these constraints are not a problem for you, this is a great battery.

PROS

  • Heavy duty
  • Good warranty
  • Good power storage

CONS

  • Expensive
  • Heavy

This battery is fairly similar to Renology’s 12 volt battery. It is a 100 amp/hour battery that should work with most gate openers. It is roughly the same size and weight as well. But it does have a few features that Renology’s doesn’t. Notably, it is designed for mounting in any position, making it a more versatile battery overall. 

WHAT WE LIKE

This Universal Power Group battery is another solid option if you need a 100 amp/hour battery. It is durable and high-quality with a one year warranty. Although it does also have a relatively high cost when compared to the first two options on this list, it is a well-built product that should provide you with reliable power.

  • Reliable

Like the nine amp/hour battery above, this one is made by Mighty Max. Unlike the above battery, however, this one packs 100 amp/hour. While relatively close in cost, this is the most cost effective of the three 100 amp/hour batteries listed here.

As for installation, this battery is fairly versatile, and can be installed in any position except upside down. Like the other Mighty Max battery, the leak-proof design here is effective and safe, making this a reliable product overall.

WHAT WE LIKE

Mighty Max makes quality batteries, and if the less powerful version above won’t cut it for you, this one is another good option. Like the other 100 amp/hour batteries here, it is quite heavy, which is something to keep in mind when planning to mount or install it. As a fairly affordable choice when it comes to 100 amp/hour batteries, the quality here is up to par.

PROS

  • Relatively affordable
  • Versatile for installation
  • Leak proof design

CONS

  • Heavy
  • Still expensive when compared to the less powerful batteries here

Choosing a rechargeable battery for your gate opener is important, so make sure you are making the right choice. In most cases, the Power Wheels 12V battery will get the job done at a great price. It is a high quality battery that will reliably power your opener without emptying your wallet, making it our top pick.
