re battery chargers
Thanks for the advice in response to my earlier post on this subject. Took
myself off to Repco as Gary recommended, gave them all the details and they
said a Projecta Handyman 12V battery (model number KM400R) is suitable.
However when I got home and looked at the box, it said 4 AMPs RMS on it. Is
this too much power for the battery??

dunno about the RMS business but otherwise - Yes, I think so. DoesHowever when I got home and looked at the box, it said 4 AMPs RMS on

it not have a trickle/boost switch?

Yup it is. The item I bought from them was like a wall plug pack, you know,
the sort of thing that powers telephones etc, but a large one. It had two
leads with battery clips on them coming from it and was limited to 1 Amp. It
was specifically called a trickle charger. Bought it about 2 years ago.

re battery chargers
I think your one looks more like the Arlec ones correct? Half shoebox sized
with a couple of LEDs on the front to tell status. $40 or thereabouts?
It is probably not the best solution, but should work OK. I doubt it puts
out 4 AMPS anyway. The AGM batteries like to be charged with 500mA-2A, 4
should be fine though, but I wouldn't leave it on longer than overnight.
Sometimes they need more time than that to fully revive though, but use a
lower current.
Jaycar sell a kitset that fits inside Arlec chargers (and poss that one?)
that monitors battery status, and limits current to a few hundred mA when
the battery is charged (trickle charge). Its a kitset though - soldering
etc required...

dicky smith, Jaycar etc sell plugpack chargers as Gary mentioned. Something
like this might be good http://shorterlink.com/?K80F0J but 1-2A probably
better if you can fine one.
The best solution is a nicely regulated test bench power supply with
adjustable current limiting. This would do the job nicely

This would be OK but slow... and the terminals would need replacing with biglike this might be good http://shorterlink.com/?K80F0J but 1-2A probably

$358!!! You can buy a new battery for less!!The best solution is a nicely regulated test bench power supply with

re battery chargers
guys,
The tech section of road and track magazine mentions
that up 6A is fine for the AGM battery:

so... who was top-down in this weather ???

I disagree with road & track then - if you want your battery to last a longThe tech section of road and track magazine mentions

time. There are lots of other resources on the web about AGMs - people use
them for powering homes, electric vehicles, emergency power supplies in
hospitals etc & correct maintenance counts in these situations.
humour... anyway, mine was only $295$358!!! You can buy a new battery for less!!
