Hybrid Car Battery Replacement FAQ

What's the difference between 'Standard' and 'Performance' options?

The BeeMax™ hybrid battery replacement is quite simply the highest performing, longest-lasting aftermarket hybrid battery available. While others claim to use "the very latest technology", only Bumblebee has our proprietary BeeMax™ 16-bit extreme-precision cell matching process. With specially developed software, we isolate the unique power "signature" of hundreds of newly manufactured cells by sampling their electrical characteristics including voltage, amperage, impedance, charge and discharge rates, capacity, and others. Our software then uses a sophisticated algorithm to identify the optimal set of cells that are perfectly matched. We then use this information to build each pack.

Because hybrid battery packs can have upwards of 200 cells or more, even tiny variations in power characteristics from cell to cell can make a huge difference in the performance and reliability of the fully assembled battery. With BeeMax™, you don't just get a replacement pack with "new cells", but a truly optimized battery system. This unique approach is based on many years of Honda and Toyota hybrid battery-specific research, with refinements over the decades, based on actual operational experience.

Both the Standard and Performance variants of our BeeMax™ line give you the benefits of this proprietary process and are built with new, high-quality cells. However the Performance version uses premium grade cells - certified by their manufacturer to have the highest performance characteristics, cycle life and runtime. The Standard BeeMax™ is a good option for general purpose requirements, whereas the Performance BeeMax™ is recommended for vehicles being operated in demanding environments, or for owners looking for the best available power output, fuel economy, and longer charge / assist periods.

What is the Core Deposit?

When you purchase your new hybrid battery from Bumblebee Batteries, a fully-refundable “core deposit” will be added to your order and charged during check out. This amount will then be refunded back to your credit card once we receive your old battery back.

Your new battery will be shipped in special reusable packaging that allows you to easily return your old battery back to us. The shipping cost covers both the shipping of your new battery to you, and the return of your old battery back to us.

How difficult is it to install the battery? Can I do it myself?

Yes, you can install the hybrid battery by yourself. In fact, most of our customers choose this option and are surprised how simple it is. However, it does take time and you should be reasonably comfortable using basic tools.

We have created a comprehensive video that walks through the battery installation process for a Honda Insight. You can watch the video here.

How do I return my old battery?

When you purchase your new hybrid battery from us, a fully-refundable “core credit” for your old battery in the amount of $500 or $750 will be added to your order at checkout, in addition to a shipping fee based on your destination state, originating from Oregon. The shipping fee includes both the shipping of your new battery and the return of your old battery.

We ship your new battery in special reusable packaging with a pre-paid shipping label for your old battery. Simply unpack your new battery, put your old battery into the same box with the provided pre-paid label, and send it back. Once we receive your old battery, we will refund the core credit back to your credit card within 3 business days. It’s that easy!


To receive your full core credit, your old battery must be packaged using ALL original packing materials that were provided with your new battery!

What if I'm not comfortable installing my new battery myself?

Not a problem! We have a growing network of authorized partner service centers throughout the continental United States. When you place your order, we will happily recommend one and ship your battery there, or we can ship to another service center or mechanic of your choice.

Just drop us a line at 888-968-5005 or send us a message from our contact page.

Do you sell hybrid battery cells or sticks individually?

Yes. You can find them on our Accessories Page.

However these come with only a 30 day DOA warranty, and no support will be provided. This should only be attempted by those with experience working on hybrid batteries. They typically come in matched sets of 20. We can sell them individually, but they should not be mixed with old OEM sticks.

We can also supply you with untested OEM sticks. These are as removed from a core.

Please keep in mind, these cells age at different rates, and using mis-matched cells may make your battery’s performance deteriorate at a rate higher than normal. The battery pack is as strong as the weakest cells. Therefore, the lifespan of the pack will be affected whenever some of the cells are not working optimally. This is why we generally recommend replacing the entire pack with a new one containing all new, balanced cells such as our MAX-IMA™ battery.

I saw a cheaper hybrid battery somewhere else. Why is your product more expensive?

As the saying goes, "You get what you pay for." At Bumblebee Batteries, our goal is not to offer the cheapest product, our goal is to provide the highest quality, best performing, longest lasting hybrid battery replacement for our customers.

Our premium quality batteries are priced substantially lower than what you would pay going through your dealer. Our cells feature 25% more plate surface area, enabling higher capacity and power output than the factory-installed hybrid battery. Thanks to advancements in manufacturing technology, our battery assembly is able to be wound tighter, fitting more plate material into the same industrial D-cell battery case.

The positive and negative collectors have been redesigned to allow for approximately 50% more weld points between the plates and the collectors. The negative collector is welded to the battery case, rather than just pressure contact. These improvements allow the highest capacity and lowest internal resistance of any hybrid battery cell on the market!

Here are five reasons why we believe the BeeMax™ battery from Bumblebee Batteries is the best value available.

We realize some vendors are out there willing to sell "refurbished" replacement batteries with lower-grade components and testing methods. We are not willing to do this because we don't believe our customers should have to roll the dice when it comes to the quality of an investment as important as your car's hybrid battery.
