The UK/EU Honda Hybrid IMA Expert.

Welcome to my webpage!

Please note I only deal with UK/EU Honda IMA hybrid vehicles.

I do not currently deal with any other make of hybrid. 

I have owned many Honda Hybrids over the last twenty years and have researched the electronics and IMA systems.

 Most people contact me about failing IMA batteries.
This is now a common occurrence, as these vehicles age and the IMA batteries near the end of their natural life.

Unfortunately there is no cheap solution if you really need a replacement IMA battery.

Honda Dealers are not especially interested in fixing these vehicles, and most are not very knowledgeable about them. They are rare, with only around 250 G1 Insights and 1000 HCH1 Civics in the UK, and most dealers won't see very many. Dealers follow a set diagnostic and repair routine and don't normally think outside the box for solutions. They are not well placed to tackle quirky IMA problems. You will find if you do some internet research that, apart from US based companies, I am virtually the only person dealing with IMA batteries and problems in the UK other than Honda themselves. The generation 1 Insight is a delightful lightweight, aerodynamic futuristic looking collector's car capable of insane mpg. Its a marvel of determined engineering, and they are rapidly appreciating in price and look likely to become a good long term investment.

So what services do I offer?

1) I rebuild and fit/fix replacement IMA batteries using brand new high spec Nimh cells.


I do not use second-hand cells, reconditioned cells or sticks, or cheap low spec cells from e-bay.

Working closely with others in the USA, we have sourced a supply of excellent new cells to repair the IMA batteries. These are used to rebuild IMA packs, which are then charged and tested before awaiting fitting in customer cars. I charge considerably less than the Honda UK dealers for this service. I also use higher specification cells and provide a three year unlimited mileage warranty. The installation process takes about two hours, so involves minimal vehicle downtime. The benefits of a new high power IMA battery are increased mpg, increased performance, lower emissions, cleared fault codes and longer and stronger assist and regeneration.

The cost of a Honda G1 IMA Battery including installation is £2,200 exchange. UK/EU Only.

2) I build and fit a special high voltage IMA battery charger/discharger. 

I have developed a special low current IMA battery charger /discharger which can help to rebalance and recover a failing IMA battery. This is a much cheaper option than a new battery but carries no 100% guarantee of success and is not a magic bullet. If your battery is really bad and unlikely to be helped I will tell you on the day and you can then decide if you wish to go ahead with a charger or fit a new battery. The charger fitting process takes about one hour so involves minimal vehicle downtime. The benefits of an IMA battery charger/cycler fitted to a suitable battery are increased mpg, restoration of IMA performance, lower emissions, cleared fault codes and longer and stronger assist and regeneration. I always recommend trying a battery cycler on an OEM battery before finally replacing it. 

The cost of the IMA Battery charger including installation is £350. UK/EU Only.


3) I build and fit a manual IMA control system IMAC&C (IMA Command & Control) for the enthusiast driver wanting total control over how the IMA system works. 

This involves the fitting of a specially developed control circuit to the car and additional wiring to enable the manual control of the IMA system. This allows the user to control how and when the car assists or regenerates, so the driver can help a weak battery last longer. It also enables the sporty driver to use more assist for extra performance on demand. The car's own computers still have final control, and the IMA system remains within safe limits even when modified.  Over 100 of these are now helping owner's worldwide get the best from their cars. The benefits of the IMAC&C system are manual IMA control, increased mpg, increased performance, lower emissions, stronger assist and regeneration and better management of the IMA battery condition.

The cost of the built and tested IMAC&C device including installation in UK is £600.


4) I build and supply a special Honda IMA dedicated OBDII diagnostic and vehicle monitoring tool

OBDIIC&C (OBDII Command & Control) which displays a large range of vehicle parameters on a dedicated dash mounted instrument. 

It enables you to monitor in real time a huge list of system parameters, read and clear vehicle error codes and it has a number of exclusive IMA related functions. Over 300 of these are currently in use helping owners get the best out of their cars. The benefits of the OBDIIC&C system are real time system monitoring, increased mpg, lower emissions, cleared fault codes and better management of the IMA battery condition.

The cost of the built and tested OBDIIC&C device is £350 including worldwide postage. 

5) I can diagnose and repair IMA related problems and carry an extensive stock of expensive Honda IMA parts.

My hourly rate for this service is £100. Parts extra. UK/EU Only.


6) I provide an IMA check up service when I will examine your car, take readings, and drive it, to give you an

assessment of the battery state of health and advice on any other issues or problems.

My hourly rate for this service is £100. UK/EU Only.

7) Other Services.

I work closely with Steve Retchless at Auto-Tech Thirsk Ltd an independent specialist garage, who does my general hybrid repair and servicing work. I've known Steve for over 35 years and he now works on a lot of my customers Honda IMA Hybrids. He has my full backup for any IMA or Hybrid problems, access to my diagnostic tools, stock of expensive spares, expertise and my full Honda workshop manuals. He can provide a courtesy car, and services the cars of a lot of customers who come to see me for IMA work.

Steve is familiar with the quirky issues that affect the Honda Hybrids (We have worked on them together for many years) and can tackle a number of mechanical problems that a lot of Honda dealers or other garages won't. For example the common Insight MK1 gearbox input shaft bearing failure.

Contacting Steve at Auto-Tech is only possible by phone on 01845 526192. He does not use the answer phone or e-mails, so you have to ring until you catch him. It's a good way of killing two birds with one stone. Many visitors now book in with Auto-Tech for general service or repairs, stay overnight in the area and come to see me the following day in Hull for IMA work.

The rate for these services is determined by Steve so contact him for details and availability. UK/EU Only.


Terms & Conditions.

Due to the high voltage and danger presented by the IMA hybrid system I do not supply batteries or chargers for others to fit. All the work is done by me personally. This guarantees the standard of workmanship and enables me to offer a no quibble three year return to base warranty. If anything I fit or supply fails within three years then I will replace or repair it free of charge.

Payment is strictly via bank transfer before the fitting appointment or cash on the day.

I also accept Paypal for postal sales.

To manage the high volume of enquiries I receive you must include your full name and address, Insight central username (if you have one) and your vehicle registration/identity number with any further communications.

To book my services once we have agreed the work and a suitable date, I require a non refundable deposit of £100 by bank transfer or Paypal(+5% to cover their fee). If I cancel for any reason your money will be refunded. If you cancel because you do not want the work doing anymore then the deposit is forfeit. If you cancel because the date booked becomes a problem then we will rebook a different date. Because my spare time is limited cancellations and no shows mean others have to wait longer for my service, that's not fair on them or me.

Parts ordered at your request for your vehicle will attract a 100% restocking fee if you cancel completely.
