Hi BZ,

In terms of physical size, any standard group 27 battery should be a direct replacement for the NG-27. As with RaggedEdge, you'll want to make sure any battery you choose provides an adequate amount of cranking amps and reserve capacity for your application.

Does that "Mexico" label on the video link mean the optimas are made in Mexico?

I am good on the power but what about the post locations are they the same>>>>>

yep..made in Monterrey Mexico

Hi BZ,

The top post locations on group 27s should be within an inch or two, depending on the manufacturer. pookie, as Wally and our video indicated, all our batteries are manufactured in Mexico.

I have two Blue tops, I charge them with one charger and the switch set to "ALL" is this correct? Or should I charge them seperately?

This weekend after they were both charged engines would not crank over when set to ALL. Only when set to "1" number two even thou fully charged would also not start the motor.. I`m guessing the battery is dead. It only seems to hold enough power to crank over for a short period of time.

If I take it to Autozone will they be able to tell me if it`s no good?

Jim, anyway to determine the age by the numbers on teh battery?
I bought the boat last year and the owner said he replaced a battery.. I`m not sure which one thou..

Hi ICDEPPL, without actually taking a look at the way your boat is wired, it’s difficult for me to say with certainty which setting is correct for charging. I was helping a friend work on an Elco electric launch last weekend, which has eight 8-D batteries and four chargers. When he first took possession of the boat, all the batteries needed to be replaced. When he called Elco and asked for assistance with the wiring and charging configuration, he found out the wiring was totally different than the way the boat was originally configured at the factory. Apparently, when the batteries were replaced by the previous owner, the marina doing the work changed the configuration, which ultimately shortened the lifespan of those batteries.

You do have the option of charging each battery separately. If you can fully-charge a battery (13.0-13.2 volts for BlueTops except 34Ms) and it maintains a charge close to that level for 12-24 hours afterwards, without being connected to any draws, it’s probably in good shape. If the battery can hold a charge when disconnected from your boat, but loses voltage when connected, you probably have a current draw on your boat that is draining the battery. Autozone can perform a similar “charge and check” for you.

You can determine the age of our batteries through the first four digits of the serial number. The first digit is the year and the next three digits are the Julian day of production, so all batteries being produced today will start with “0152” because today is the 152nd day of 2010.

Thank you for your answer.. I charged the battery to 13.xx but as soon as I take it off the charger (nothing connected took the battery out the boat) the voltage starts to drop.. within a minute its down to 12.4v So Thats toast.
One more question, where can I find the serial number?

thanx
Dan

Hi Dan,

The serial number can be found on a white, 1"x3" "non-spillable" decal on the side of your battery. There is also a side burn code stamped into the side of the case. The first number will indicate the year and the next three numbers will indicate the Julian day, just like the serial number. I hope that helps.
