Question: Is this a 3 D cell battery replacement?
Document: My original battery failed (after 3 years) and this NiMH replacement works perfectly and at a reasonable price. Highly recommended.
Better than the Ni-Cad original but I wish these came in LSD technology and it seems they could have a higher capacity. The 1/2 D cells that make up this pack are actually slightly larger than half D size. D nimhs commonly have 10,000mah capacity. Seems these cells could have 5000mah at least.
Seems to put out a "brighter" light than my old battery, but it should-right? The real test will be after a few years. Wish I had dated my old battery but I think it lasted 5 years or longer. I put the date installed on this battery with a "sharpie". I expect it to last at least as long as the old one. Follow up 3/2/13  Battery still going strong.
The battery to get when you need a replacement! I have no issues and think this is a great product!
Only had it for a couple of months, but so far it seems like an excellent replacement for the original battery.
Good replacement for original battery. Long lasting and bright. Have had it for about two months and use it regularly.
Was a perfect replacement the original old battery. Has longer life under full and constant use with quick recharge and recovery.
The replacement battery was just what I needed. Easy to replace and works really good. Would recommend this battery to anyone.
Perfect fit, works great, no hassle with this product. Recommend it to anyone needing a replacement battery. You'll not regret the purchase.
Mine came with a NiCad originally. Memory effect, etc.This is a direct replacement NiMH battery. I recommend it.
