[SSGN]

I had a Kestrel 4250 meter and the batteries leaked and wrecked the meter. I have found out that this was somewhat normal and by design the acid went onto the circuit board and ruined it. I ordered a new unit from Kestrel (5100 Racing meter) and they will give you $ 63 towards the new one if you send your old one in no matter what the condition. The new meter has a warning and explicit instructions to you only Energizer Ultimate Lithium batteries. This might be a good idea for you guys with the older units to minimize leakage. Personally I think I will use these batteries in all of my Maglite flash lights. Hope this helps
