Title: Battery charger / optimiser recommendations.
Post by: tricky1138 on January 7, 2018, 20:56
As the MR2 is now sitting unloved in the garage, the battery is going flat.   s:( :( s:(  

I've got a battery charger so have charged her up but as normal something (usually baby related!) comes up so I haven't gone out and the battery has gone flat again.

Rather than keep charging it up and letting it go flat again, can anyone recommend a battery optimiser that is just left plugged in all the time till I want to use it?

CTEK XS0.8 - it's kept the battery going in the Elise for the last couple of years parked up for 6-8 weeks at a time (until it finally gave out at 10 years old!)

Saw your Facebook post as well but in case someone on here searches for the same thing

Had that one recommended to me by someone when I asked the same question on here a few weeks back. Came with a short quick disconnect loom that can be left permanently attached to the battery.

Hi I bought one of these 2 years ago January 2016 and its brilliant  m https://www.amazon.co.uk/gp/product/B00 ... UTF8&psc=1 (https://www.amazon.co.uk/gp/product/B00DW6RHN2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) m
I recharged a battery that hadn't been used for 4 years the original MR2 battery then put that in the car and re-charged my current battery it is the AA Battery Charger & Maintainer, For 6V & 12V Lead Acid and Gel Batteries its specs are as follows it also comes with really long leads and adapters. Its currently £29 I bought mine for £28 from Amazon, I wouldn't hesitate to recommend it. I bought a bigger battery for the MR2 that I managed to shoehorn in much better than the toy battery they come with.

Provides the best type of charge to prolong battery life
Intelligent built-in microprocessor
Suitable for all types of 6V & 12V lead acid and gel batteries (IP65)
Reverse polarity protection
Short circuit protection

Hope that helps.

Stavros's AA battery recharger recommendation looks like a rebadged version of the baby Sakura. I needed to recover and recondition the battery in my Audi A6 and bought the big daddy version: "Sakura SS5037 Intelligent Battery Charger, 5.3 Amp" - there's also a trickle cahrger / maintenance mode on most of their models.

Several friends use these for sports cars / GT's that aren't used very often and apparently they're pretty much identical to the Aston Martin ones (DB7 generation), so I figured it would be fine for my little motors :)

I also have a Ctek - mine have with an adaptor that you can hardwire to the battery terminals, so you just have to open the engine compartment and plug it in.

Unfortunately I had to take the conditioner off the MR2 as the battery on my wife's car was flat, then the battery on the MR2 went flat  (:< >:)
