REFLECTOR: Battery Advice

Mon Dec 10 10:37:44 CST 2012

Rich & Mark,

Being in the automotive business for 30+ years, I have seen a number of
problems with gel cell batteries like the Optima. Most of the problems
originate from the batteries being run down completely. They can be very
hard to recharge when drained, even when relatively new. This is a link for
proper charging of Optima batteries:

I chose to use a standard Group 31 battery in my 173FG.

Optima's have gone up in price recently. The used to be less expensive than
any certificated battery. I love them for they have such a long shelf life.
I have one out in the garage that's probably 6 or 7 years old I use to jump
off any dead battery. Still kickin' strong.

I've been hearing talk about the optima. Right now I'm in "triage" mode -
nowhere close to gold-plating the system.

I will look into the Optima's and if the price is not unreasonable I'll buy
that instead - I'm sure it's not more than $100 or more...

Hi Rich,

I thought I'd throw this over to you and the group: is anyone using Optima
or similar AGM batteries. When my Odessey goes I will consider an Optima or
Johnson Control AGM battery. I've fairly good results with the Optimas, when
properly sized.

That's very generous, but I am not someplace warm, and I will need to
replace this battery anyway so I think I'll need to just get the order
turned in - maybe this week.

Hello Rich,

I have a 4 year old Odyssey Battery that I replaced in my Velocity.

It tests fine but I will not fly with it.

If you live somewhere warm, I would consider flying it down to you sometime.

I have an airplane battery which was dead for 10 years, but had very little
usage prior to that (only a month or so).

I want to use this battery just for starting and possibly some slow-speed
taxi work. I plan to order a new battery, but I'd like to continue working
on this plane using the old battery until I'm ready to permanently install
(and properly maintain) a new one.

I've already tried charging it, and it didn't seem to take a lick. I only
charged for about 15 or 20 minutes though - once on a medium speed charger,
then connected to a car battery with the engine running.

Does anyone have a tip for reconditioning the battery for temporary use?
