I Bought The Lightning Pack 4000n Charger Over The
I bought the Lightning Pack 4000N charger over the internet from RipVan100 in the USA (www.ripvan100.com/products_recharger.htm) after reading many good reviews. Their mail order service was very fast, and I'm entirely happy with this purchase.
The Lightning Pack 4000N is actually two independent chargers, each for two AA sized NiMH cells. For example, you can put a pair of completely flat 1600mAH cells in one channel, and a pair of almost fully charged 2500mAH cells in the other, and it will carefully bring all of them up to full charge within about 3 hours (depending on the battery capacity and state of charge), and drop each pair back to a trickle charge at the right time.
I've used it with a variety of NiMH AA cells, including Sanyo, Powerbase, Sony and Energizer ones, and it usually brings them up to full charge then keeps them on trickle charge without any fuss or drama.
At first it had a tendency to stop charging in a 'fault' state, but I eventually worked out what the problem was. The microprocessor is always watching the battery temperature. If it's just charged some batteries and you take them out then put in others and immediately reconnect it to the power, the residual warmth confuses it. If you let it cool down for 15 minutes before charging another set of batteries, there's hardly ever a problem.
I'm very happy with this charger, except that its holders can't accommodate AAA cells, even though they're supposed to. It charges quickly and treats AA batteries very carefully to ensure their maximum life.
I'm the person who wrote the original review. Since then I've been using higher capacity NiMH cells e.g. 2500mAH and they totally confuse this charger. It will almost always cut off the charge prematurely because it's lost track of the charging process.
I don't use it any more and instead I use a Tevion unit I bought cheap from Aldi a couple of years ago. It charges much more quickly and doesn't have any problems.
It looks like the company selling the Lightning Pack 4000N has gone out of business anyway. I think I know why.
