Honda doesn’t  sell new hybrid batteries for any NiMH packs. For an average of about $2,800.00, they will sell you a “refurbished unit” and gladly take your existing pack to refurbish and sell to someone else. In the end you will be out the money spent and still have a used/refurb battery pack. Panasonic made the hybrid batteries and they no longer make these units so they are not available as new. So for a fraction of that cost you can have a personalized programmable MAXX-VOLTS charger to command at your will to take a charge, balance the high end of your battery pack and potentially have a good working car again without the IMA lights and with improved MPGs again.

We will not speak of whose is better or worse and why, however we will overview the features and benefits of ours and allow you to decide who is building a quality engineered and well thought out unit at a reasonable price.
  • Programmable DIGITAL 24hr timer with AM/PM clock and internal battery backup!
  • Internal clock battery does not depend on being plugged in!
  • Easy to understand AM/PM clock with programmable ON time and off times - no math or guesswork required. You want to set it for 5am and have it turn off at 8am for your morning commute? You got it....
  • Able to be used as a battery warmer with light topping off of the battery in the AM for maximum efficiency and no waiting for max assist and regeneration, pending your ICE engine has reached normal operating temps.
  • Able to be used as a SOAK charger for up to 23:59 hrs for initial recovery of a low voltage battery
  • 1 minute resolution. Start charging at 9:27pm and stop charging at 11:04pm? You got it!
  •  No guesswork or dangerous poking or prodding of high voltage electrical terminals with a crappy voltmeter to try and figure out the state of your battery charge/volts.
  • Allows you to monitor/calculate the energy going into the pack and determine when current tapering (FULL PACK) is occurring.
  • Modular construction with CPC locking connectors.
  • Both the charger and the car's charging port BOTH have female CPC connections complete with locking dustcap when not in use!
  • No bulky annoying wires dangling around. When the charger is NOT in use, you can cap off the car's port for an OEM finish
  • There are NO high voltage wires hanging out of the charger unit to tangle or trip over and no exposed high voltage wires or prongs to accidently touch together.
  • Material construction quality and engineering
  • Charger high voltage purpose use cables are rated for 300V and not some inferior and potentially dangerous 12v rated automotive wire.
  • Battery pack to charger reverse electrical flow protection built into battery harness.
  • Positive electricity from battery pack cannot flow from high voltage positive in our wiring harness back to the charger.
  • Current can only flow from charger to battery pack, even if the car was started accidentally!
  • Our standardized 9 pin CPC connectors mean that our charger is expandble for additional features in the future such as datalogging and discharging.
  • Connections are soldered, heatshrunk and many connections potted for electrical connection protection.
  • Intermediate cable from car to charger are CPC male twist and lock connection. No loose connections and a securely and surely locking connection that won't pull out.
  • Strain relief plug ends protect wires from bending, wearing out and pulling out of harness.
  • Brand new power supply cases designed for ventilation and cooling.
  • Slow blow arc quenching high voltage fuse at battery connection.
  • Internal power supply fuses

  • Standardized 9 pin CPC connectors for forward and reverse compatibility with GenesisOne and Hybrid Rev chargers.
  • If you bought a car with a GenesisOne or Hybrid Rev Charging port, our MAXX VOLTS charger will work with it!
  • If you own a GenesisOne $$$$ charger or the like and want an additional unit more portable or for another one of your hybrid's, our MAXX VOLTS charger is compatible! It is the most nimble and feature rich charger available.
  • High visibility LED power supply cooling fan
  • Protects power supplies from overheating.
  • Doubles as an audio and visual indicator that the charger is powered on and charging. Even from inside your home you can tell if the charger is on.
  • Forget that the charger is still on and ready for a drive? With a LED powered fan in your rearview mirror makes driving off with the charger on and attached virtually impossible.

The unique high voltage charging system we offer has been designed to serve the market of Honda owners who invested in Hybrid automobiles with the idea that the high MPG fuel efficiency of this 66mpg hwy rated vehicle would save a lot of money in fuel costs over time. Whether you bought your Honda Insight new or used, you probably realized as time passed, or in case of buying a used one that the mpgs started to drop over time. The car started charging itself more often which loads up the engine and drags down fuel efficiency.

The NiMH battery packs in the Honda Civic Hybrid vehicles consist of 132 individual battery cells robotically welded in series consisting of 11 pairs of 12 welded batteries sticks each. Through the battery pack, electricity travels end to end + to - until it runs through each of the 132 nickel metal hydride battery cells where the total voltage ends up in the 154-185 volts range depending on the state of charge of the pack and its overall battery health. Now the Honda IMA system does a fairly good job managing the charging and usage of this electricity but it the pack as a whole singular unit and does not, nor have the capability to manage each individual of the 132 battery cells individually. Over time these batteries can become out of sync with one another with slight voltage and internal resistance differences. This will reduce the range of effective useable area the IMA system has to operate in between charging and discharging (ASSIST) power.

What our charging system will do is give the end user the ability to charge their IMA battery pack at home or the office via the standard USA 110v AC plug you would have in your home. This ability to override the IMA system telling the IMA motor when to start and stop charging the battery pack will allow you to fully charge the pack without the IMA computer playing referee.

The Maxx Volts Charger system is programmable to allow you to set the start and stop times of the charger. This will allow the charger not only to fill, but also to soak charge the weaker cells within the pack. Balancing a pack is bringing all of the 120-132 individual cells within the pack to the same voltage as one another so that their charge and discharge characteristics are as close as possible to one another.

Charging at a safe charging current (with our Maxx Volts Charger), until the stronger cells with the highest voltage reach capacity, they will transfer any additional energy into a few degrees in temp change while the weaker, lower voltage cells "catch  up" and continue rising in voltage.

P1443/P1447/P1449/ P1600/P0A7F/ diagnostic trouble codes from the OBD II scan port are the typical codes that may be eliminated with MAXX VOLTS charging system.

Our Maxx Volts Programmable charger has a built in voltage and current amperage display. We will provide benchmark figures to look for, what to expect and our charging system will also slightly reduce current amperage when it is full or nearing full capacity of the battery pack.

This will depend on a number of factors including the overall condition of the pack, the climate and mileage of the car, however our customers have used our chargers anywhere from monthly to each week to keep their pack balanced and charged.


Our home charging system will allow the end user not only to charge their pack, but also to BALANCE their NiMH Honda battery pack. In most cases this will eliminate the IMA light, the lack of the cars ability to assist and regenerate power to the battery pack. It can help keep off IMA lights and may allow you to pass smog inspections.

Significant improvements have been obtained with nearly every NiMH Honda Hybrid battery we have tested and reconditioned. What is nice about our charger is that under the worst condition hybrid battery, our programmable MAXX VOLTS charging system has still worked great as a daily maintenance charger set to provide a pre-programmed daily boost to a weathered pack and still give useable life for daily driving for just pennies in electric which more than pays for itself in MPG gains.

**Must have a salvageable IMA battery to start with. Extreme battery neglect, ignoring IMA light for months or years, repeated resetting of BCM memory by deleting OBD codes or disconnecting 12v battery to try and fix your deteriorated IMA battery, driving  the car with a deteriorated or dead 12v battery, overheating, extreme mileage, etc. may adversely affect your results and in some cases further action such as investing in our discharger or replacing cells may be necessary for best results.
