Hi,

I was having a look around for battery chargers recently, and many support trickle charging but only a few mention support for sealed lead acid batteries, or one of there other names :)

Is it fine to just buy a super cheap auto charger or similar? I occasionally need to charge my battery due to not driving the car enough. The alarm can drain the battery within just over a week of not driving :(

There are lots of chargers on ebay but only a couple mention sealed lead acid battery on the supported list of batteries...

Thanks,

Gareth

I had a problem with the charger I got, " apparently " there's different current amp things ?

Speak to a battery joint for some pro advice.

I'm looking at getting a new trickle charger with the connections wired in full time for easy access and safety.

trickle charge isn't technically correct for lead acid batteries. all lead acids should be float charged, however i've seen plenty of chargers that say both trickle and float on the same package.

the main thing with a sealed battery is NOT to charge it too quickly. all batteries produce hydrogen as they charge, if your charge rate is too high this will burst the valves in the battery and ruin it. a nice gentle charge rate will bring you up to full capacity and then the battery should be float charged to maintain it at full.

Yes I also noticed some ads mention a float charger but do float/trickle charger and then go on to describe trickle charging...

What happens if I do get a flat battery? A float charger won't work then...what's the best thing to do? Jump-start or use a larger battery charger?

I use a solar panel and regulator. I wired a plug in above the rear number plate. But I get the SP and reg free from work. Its only a 10 watt unit and we have recently standardised on 30 watter's for all our sites.

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
