I read your other thread - some gentlemen commented it may lack of charging/discharging protection circuit and could either prematurely damage the battery or cause fire/explosion (via non-regulated charging from alternator or over discharging). I mean this Battery tender made Li-Iron battery is soooooo light and cheap (compares to those listed in this thread)... we ElIGE owners shall jump all over to grab one - if there is no concern of battery causing fire / explosion

Who can get a confirmation from Battery Tender that this series of battery can be used in 4-wheel autos?
I have had no problems, and I do not know how many starts it will take before failure since I do not let it go to that level as it will damage the battery. I have a cut off switch and I use it when I won't be using the car in a while. The "fire" concerns are from lithium ion, not lithium iron, which is why I tried to nip the misunderstanding at the bud, but obviously I was unsuccessful. Actually there are lotus users of liFePO4 batteries, and yes I am surprised there aren't more. Easy weight savings.

(Update) I just put the lifepo4-specific tender on just to check, and it says my battery condition went from flashing green to 100% in a few minutes, which means its healthy. Also the box specifically says 60% lighter than agm, no risk of leaks, no risk of fires with punctures.

I picked up a basic duracell battery from my local batteries plus, which seems to work ok, but it slides back & forth. The stops on the battery where it is held by the bracket are about an 2 inches longer than the length of the bracket, allowing it to move.

Does anyone have a list of batteries that the stock bracket will hold tight?

You mean it slides left to right? (Or back to front of battery)?

I'd just make a new bracket (riveted, welded), but uncertain as to what you mean.

My car has no left to right stops IIRC.

You could also move where the bolt fits into floor.

Ppl have moved where the bolt screws in. Also replaced the "nut" when something broke.

Don't remember that it is difficult.

Can you return that battery for refund?

If not, I'd weld up a better bracket (can be riveted).

A cheap guy would take a piece of wood, route out where the lip needs to go, add some velcro (to floor/wood/battery) and bolt it in. I am cheap, btw....

I bought, like others, a nice USA Deka AGM battery. I like it; bolted right in.

I left my Lotus back home, moved away, and no one started it up like I'd asked (and no power to run the battery tender)

I'm going back for a week, and need to get a new battery delivered. (the current battery sat thru winter and has been dead for a few months... I'm assuming it can't be jumped and re-charged?)

Anyhow, I need a new battery, and I don't know the width/length to fit the brackets, which I assume are still factory.

Would this battery from Sears work?

If not, could someone please link a good agm battery that will fit w/o special brackets and doesn't cost an arm and a leg? Thanks.

My Braille battery seems to have been deep cycled while sitting in service and it is dead.
I cannot seem to get my Ctek 4.3 to recharge it. The stickers came off, so I'm not sure which version it is.
I'll take some pictures so I can reorder a good one.

Unless once these are depleted so low they can be recharged back into good shape?

Braille is the same as Big Crank and Deka, except the Braille is 2+ times the cost. If you can't resuscitate the Braille I'd advise you buy the Big Crank or Deka. They're all made by East Penn in the USA.

For what's it's worth I've drained my Shorai completely several times and it still comes back to life. I honestly thought it was toast each time. Their customer service is outstanding, with them replacing an out of warranty battery for my ZX-10R at no charge. They even replaced the battery I sent back with the larger, more expensive battery.

I'll have to find the relevant Deka/Big Crank that fit in my battery bracket then. Too many options of both.
I have a charger for the battery, but I don't think it can handle a battery this low. I'll have to see if anyone else has something I can use.

I used a Deka ETX18L and ETX20L in my C6 Corvette. You can just use the number and find the same battery under a lot of different names. Chances are you can pick it up locally. Examples:
