What is a Grid Charger?
A grid charger acts like a trickle charger for your Honda Insight or Honda Civic Hybrid IMA battery. There are 120 (or more) individual NiMH batteries in the Honda IMA battery 'pack'. Each one is about the size of a typical D cell battery. The car's battery management system uses 20%-80% of the IMA battery cells actual physical capacity. Over time, due to every cell in the battery pack having its own level of internal resistance, charging/discharging at slightly different rates, as well as other factors, the individual cells become out of balance with each other. This means that the cells within the battery pack can have different charge levels and are no longer 'in sync'. Some cells can be 'full' while other cells in the same battery pack are 'empty'. As a result, the overall pack is limited to the weakest cell when discharging and the strongest cell while charging. The wider this imbalance becomes, the narrower the usable range of the IMA battery becomes. This leads to the check engine & IMA lights coming on and Insight P1447/P1449 or Civic Hybrid P1600 DTC codes. The car cannot correct this imbalance problem on its own. This is why your car needs help - help in the form of a grid charger.

The grid charger very slowly charges the pack to its true 100% capacity. The slow rate of charge is intentional, so the battery pack is not damaged while using the grid charger. When each individual cell reaches its true 100% capacity, the extra energy by the grid charger is given off as a very small amount of heat. Cells that are not yet full continue to charge, until all cells reach their true 100% physical capacity. This forcing of all cells to their maximum capacity re-balances the pack. All Hybrid Automotive grid chargers run the IMA battery cooling fan while charging and easily dissipates this heat. NEVER use a grid charger that does not provide for IMA battery cooling while charging!

This re-balancing of the IMA battery cells is the key feature of a grid charger. Re-balancing the IMA battery pack normally eliminates the IMA light and Insight P1447 or P1449 DTC codes or Civic Hybrid P1600 DTC codes and restores regular IMA battery performance. It also improves MPGs as the car is no longer constantly background charging the IMA battery.

All of our customers report significant improvements when using a grid charger. Most have already gotten an IMA light and P1447/P1449 DTC codes on their Honda Insight or Civic Hybrid P1600 DTC before buying a grid charger. With regular grid charging, the IMA light can normally be eliminated and battery life significantly extended. Several customers have extended their battery life well over a year or more by regularly using their Hybrid Automotive grid charger.

Why should you purchase your Grid Charger from Hybrid Automotive?
  • Cost - A Hybrid Automotive grid charger is a fraction of the cost of IMA battery replacement.
  • Safety - Hybrid Automotive proudly uses positive lock CPC connectors, quality 300 volt DC high voltage wiring, PET sleeving, and self-cooling metal charger cases for maximum safety. All grid chargers, including the advanced Civic Hybrid charger systems, include IMA battery cooling capacity. Without proper IMA/IPU fan controls, a grid charger can easily overheat and destroy your IMA battery. Avoid cheap chargers that do not have this critical capability.
  • Quality - You will not find garbage eBay power supplies in our products. We do not use cheap generic import power supplies or secure our internal components with zip ties or hot glue. All Hybrid Automotive chargers include IMA cooling fan circuitry standard and use quality Mean Well internal power supplies which are hard screwed to the charger frame. We use brand new metal grid charger outer cases with built in self cooling capabilities. In addition to keeping your IMA battery cool, the grid charger self-cools to ensure maximum life span.
  • Warranty - All grid chargers we have for sale include a one year warranty. If the charger stops working we will repair or replace it free of charge.
  • Convenience - Our grid charger kit includes *everything* you need. We source over forty unique components that are included in the kit from around the world to ensure that you have everything you need. You will not have to scramble to find the proper connectors or plugs to finish your installation.
  • Peace of mind - We are an established business, we do not pop up online and sell a few of the most basic chargers, then disappear as soon as we get your money. We are here for you if something should happen, and we will still be here for you next week, next month, next year, and beyond.
  • Experience - Hybrid Automotive has built well over 100 grid chargers for concerned Honda Hybrid owners just like you. Hybrid Automotive has been in business since 1999. We have almost 15 years experience specializing on Honda automobiles. We are an expert with your Honda and will work hard to earn and keep your trust.


Will a Grid Charger fix your IMA battery?

The vast majority of our customers report significant improvements when using a charger. Most customers have already gotten the IMA light before buying a charger. With regular grid charging, the IMA light can normally be eliminated and battery life significantly extended. Some have extended their battery life well over a year or more by using the grid charger.

Unfortunately, in any one specific case, it is not possible to say for sure how much the charger will help. The amount of improvement depends entirely on the condition of the underlying battery pack itself. Even if you were to have to eventually replace your IMA battery, the grid charger is still a good investment as it will prevent the new IMA battery from returning to the deteriorated state of your current pack. There are many people that are buying brand new IMA battery packs (such as
the MaxIMA from Bumblebee Batteries) and adding a grid charger to the new pack on day one to virtually eliminate the imbalance problem that is so common in our cars.

What is the "Discharge Ready" option?

There is a lot of excitement in the area of IMA battery deep discharge. Hybrid Automotive is aggressively working on an advanced discharger that will have adjustable discharge stop points, auto tapering load, many layers or safety, and current tapering at the discharge termination point. There are no products on the market today that have these features. In order to use this discharge in conjunction with your charger, you will need the discharge ready option. If you plan to build your own deep discharger, you will need the discharge ready option. This option can be purchased later if you decide to charge only for now.

If your IMA battery is 'weak', we recommend the discharge ready option. A weak battery is usually described as one that is causing an IMA light and/or re-calibrating on a regular basis. Often a weak IMA battery will not fully recover with charging alone. Discharging helps clear the memory effect from the cells and significantly increases the improvement in capacity and performance. It is a 'shock' treatment to an otherwise failing IMA battery. If you are earlier in the process with a still healthy IMA battery and are buying the charger as preventative maintenance (which is very wise) then charging alone is sufficient and the discharge capability is not needed. It can easily be added later should you subsequently determine that discharging is needed.

How often should you Grid Charge your IMA battery?

There is no exact science on how often to rebalance an IMA battery. Many people have varied perspectives but the consensus opinion seems to be as follows: With a healthy battery, charging once every 4-6 weeks and/or anytime the car sits unused for more than three days should keep the battery in top form. Customers with degraded batteries report that they charge every couple weeks, sometimes weekly or more, depending on how much 'life support' is needed to keep the battery going.
