The results are very surprising so far. I'll post the results soon when I have collected enough data, but I think it will change the way I charge these batteries so they will last longer (take better care of them).
What this is not: a review of batteries and chargers, I simply don't have the resources to test different chargers and batteries. After reading the battery charger manual, researching on-line, and reading the results I have gathered so far, I'd change the way I charge these rechargeable batteries for longer service period for my own use.
What I am using:
Charger - LaCrosse BC-900
Batteries -
- Duracell 2650 mAH x 16 - Recently ordered off of ebay.
- Panasonic 2300 mAH x 12 - Purchased from CostCo, maybe 12-16 months old. 2 of which have been hiding in a remote control, glad I caught them!
- Energizer 2100 mAH x 4 - Purchased from HomeDepot, about 18 months old.
- LaCrosse 2400 mAH x 4 - Came with my battery charger.
- Sanyo 1850 x 2 - older - I have these guys since 2003, came with my Minolta 7Hi.
- RayoVac 1800 x 2 older - Oldest of the bunch, maybe 2002-2003.
Sanyos and the RayoVacs are relegated to maglite duties now due to their age. When I put the Energizer cells in my Pentax DL, it will not power on. But Energizers can power my flashes without any issue.
The charger comes with 4 modes:
- Charge
- Discharge
- Refresh
- Test
Here's a link to the instruction: http://www.lacrossetechnology.com/900/manual.pdf
I purchased mine from Thomas Distributing for about $60 including shipping. It came with 4 AA and 4 AAA batteries, converter to C cells, carrying case. Since I am not affiliated with anyone, I don't think I need to provide a link to Thomas Distributing, but I am sure you can do a search and easily find them on line, and I have to say the experience was painless, and very quick shipping. But shop around, I am sure you may be able to find a good deal.
Test is not completed yet, so I'll post that when I get a chance to refresh my Energizer, Sanyo, and the RayoVac batteries, that's the result I am waiting for.
I'll also post some reference sites, Steve's Digicam and Imaging-Resource all have very good reivews, and they definitely tested more chargers and different brand of batteries.
