Dear subscribers,
I got a 2x12V=24V battery stack on the firewall behind the oil cooler -
see picture
I started flying the plane in May2011 with about 350hrs since then.
I bought the batteries probably early 2010 and used them during the
start-up process of the electrical systems in the plane.
Last week I thought the first crank revolution during starting felt kind
of weak - what kind of life can I expect out of them?
Does it just get weaker and don't start the engine anymore or would it
more likely die sudden at night in IMC?
I don't have an electrical back up but vacuum instruments and a
flashlight in the cockpit.
Thanks for your input
Ralf

Enough?
Why was it smoking? Overcharging?

had his battery start smoking IMC in a Cessna 210. He made it but it
wasn't pretty.

Ditto.. put the battery or batteries behind the seat too if the CG (or

Move your hydraulic pump from its current location.
Create a small bulkhead and put the pump directly behind your seat.
The reasons are too numerous to list!
Don't even think twice about making this change.
Equally important, locate your pump breaker within easy reach on your
panel.
