Brusa is the only charger that I know of that has the Saft Profiles availab=
le. However, you should remember that when working with NiCads it is not a=
s important to get a perfect charge every time like it is with lead. Real=
ly you just need to be sure they are full enough to handle the next trip yo=
u plan on taking.

When I was using these batteries I found a decent variac based charger wit=
h a timer was fine for normal bulk charging, and an appropriately sized lig=
htbulb(s) in series with the pack was an easy way to implement constant cur=
rent finish and maintenance charging.

Also, if you do not constantly need the full range of the pack, you can cut=
down significantly on the amount of watering needed by purposely underchar=
ging since most of the water loss comes at the end of the charge cycle.

What about a two charger option? Two different zivans, one for bulk =

and one for finish?

Or a PFC for bulk and a zivan or other for finish? This would allow =

for 110 and 220 charging. What about temp control issues- when I =

charged at 10A to 56% the bat temp never went above 21C.

How often would the finish charge need to be performed?

If your Safts are still under warranty, Saft will most likely have to
approve any change in the charging regimen. Otherwise they're apt to void
the warranty.

The Brusa is a fairly well established option for these batteries, and I
expect you'd have no trouble getting Saft to sign off on it. I'm not so
sure about the Zivan. I know it claims to have a nicad profile, but I don't
think it implements the Saft algorthm.

If you're willing to ditch the warranty and take the risk, or if you don't
have a warranty anyway, then there are other (cheaper) avenues open.

Assuming the warranty is not a factor, I want to use the most
appropriate charger for the battery- Just not sure what that is under
$4K

BRUSA NLG511-SA is ~3.7k, and NLG503-lite - 2.7k (1/2 power of NLG511).

Is is OK with SAFT to charge slower than they normally recommend
in the manual (e.g. it just takes extra time but no harm to the
batteries)? If so and you don't mind long overnight charging, lite
version may be acceptable choice for you.
