Battery re-charging

[Speedzalot]

Guys I need to charge the battery in my busa due to a lack of use. While it's not flat I can feel it's not at full charge either, so my question is will the map Cole@10/10th's put in the ECU be lost if I disconnect the battery?

I dont know the answer to your question but would highly recomend you use a trickle charger like Ive been using. My OEM battery is now 9 yrs old and still working fine. This unit has a lead to leave on battery and make a port to allow charging as being parked. The unit cost me $99 from Mick Hone.

I like the idea of that but I dont have power in my garage. I need to run a cable out every time I do some work,I have a 12 volt battery connected to 2x12 volt fluro's for lights.

I hate living in a apartment

What ever you do Andrew, don't overcharge it.
Use a very low trickle charge for a max of about 4 hours.

No problem Busgo I have seen what can happen if a battery is abused.You know your doing bloody well to have yours last so long they dont make them like they used too.

I had a trickle charger and still ruined the battery so I got rid of that unit and bought a CTEK MULTI XS 3600.I can leave this unit connected for months on end and not a sign of overheating.It does not trickle but pulse's the battery which according to the battery gurus its the best way to keep the cells in top condition

No, the firmware is electrically burnt into the memory.

I donâ€t know much about trickle chargers, but the oneâ€s we use at work need the battery to be well drained (70-80% charge is considered flat) and then fully charged followed by a cooling down period to get maximum life from a battery.

Basically a battery has a life measured in charge and drain cycles so a new battery may last only 1500 charges and itâ€s up to the user to get full use from every charge and avoid opportunity charging. That is plugging the battery in for a partial charge counts as one charge but will last only a fraction of the time.

Another way to improve battery life is to “equalize charge” every 15 or so cycles to bring up any weak cells to full charge, this is done by slightly over charging the entire battery so should not be done too often or it will have the opposite effect.

I could go on and on about this but to my original question can I unplug my battery without losing my ECUâ€s memory?

Thanks Gnarbs thats all I needed to know

Recently picked up a solar panel charger from the supercheap store,cost $19.75 on special.As long as the panel is in daylight it keep's the battery topped up with a very small charge rate.Not enough to overcharge or boil.I fixed the panel to the outside wall of the shed and run the wires through a hole to the inside.I've tried it out on my truck battery which I only use once or twice a month and it keeps that topped up no worries.Now connecting it to the bike batteries when I go away on holiday.
