its the second time i bought an oddyssy mini battery for my evo VIII and it keeps dying. why is this??? anyone recommend another battery i should buy?

 

Maybe your alternator is bad (not charging properly)

 

i have the same problem. this is my 2nd battery within 2 months.


best option would be replacing your original battery in the trunk.

 

i heard that these type of batteries need to be trickle charged which means you need a special charger for them. if you use regular jumper cables and another battery from a car youll blow your cells in the battery. i think im going to just use an evo 7 battery. that should do

 

buy a battery tester like a 500amp carbon pile load tester, not to exspensive, but you will be able to load test your battery and alternator, to find the problem

 

Theres nothing that needs to be tested.

YOUR BATTERY IS DEAD!!!

I had this problem once and I moved staright to the trunk mounted battery kit. 80 bucks from summit racing and I put my stock battery back in and have yet to have a problem.

Or you can buy ETS long route upper intercooler pipe and that way you can keep the stock battery in the stock location.

Small batteries suck

 

Just from reading of the threads sound like you may need a new alternator.

I have the Braille Battery B14115 and haven't had any issues.

I also purchased the Braille Electronic Battery Charger which its been over two years and have used the charger once.

are you removing the battery in the winter time? cause winter weather below 30 will cause the battery to go bad, odyssey is known for this! i went through 4 in 3 years. just an idea..

 

im sure its not my alternator. my mechanic checked this. he said its either the battery or something like my car alarm is suckin juice from the battery

 

dude, mount your stock battery in the trunk if you dont want to run into anymore problems. Like everyone here is saying. You can also run a honda battery. Couple friends are doing that and no problems with that also.


Good Luck

 

While the cold cranking amps on an Odyssey are actually greater than the OEM battery, the reserve capacity is about half. EVOs seem to have a small constant drain that if left parked for more than a week can run a mini battery's reserve down far enough that starting becomes a problem. If you're having issues with regular driving I'd try troubleshooting a bigger drain on the electrical system coming from somewhere. A trickle charger is a great option if you plan to leave the car parked, and there are also mini chargers that you can permanently mount in the engine bay and run an extension cord to if you'll be letting the car sit for long periods
