Is there a favourite 18650 battery out there for DX torches.
The Senybor 2800mHa look quite popular. Am I right in thinking that the Ultrafire and Trustfire are a bit rubbish!
Just want 1 that will last the longest.
Any advice/experience please
Cheers

Trustfire been fine here – used them for a few years

Torchy the Battery Boy can help here

I’ve got the Senybors you mention, got them from a UK seller and they seem fine.

Based on the discharge graphs on Torchy’s website (see below) I’ve got and would recommendXtar 2600mAh’s because they maintain a higher voltage during use which is more important than 300ish extra mAh’s over the Senybor’s especially as you need to discharge the battery to a pretty low voltage to use the extra capacity. You can get them for $13.50 by joining in on the group buy described in this thread.

get them from torchys id on ebay…

Yep, I got mine from the real Torchy on ebay for £12.99 but the deal I’ve linked is approx £8.50 so if you don’t mind waiting you can save a few quid.

While we’re on the subject I’ve also just got a new charger (Xtar WP2 II) to replace the bolx I bought on DX, I got it from China through an ebay seller as Torchy didn’t have it listed but you can also get it at a discounted price through the budgetlightforum thread. Read the reviews for it on Budgetlightforums and you’ll see why it’s worth getting if you’re at all bothered about wrecking your batteries or burning your house down.
