I need a battery charger

Recommended Posts

Guys

I have a brand new Panasonic MF Battery which at present I don't need to put into my car.

I did fully charge the battery a month or so ago, at present it is sitting at 12.58V.

I really don't know much about car battery chargers and I'm not all that keen to pay a considerable amount of money as it probably won't get used very often. But I also don't want a charger that feels as though it will burst into flames at any moment.

The alternative to buying a changer is just to fit this battery to the car and dispose of the older battery. Actually, financially that might be the better option but one never knows when a charger might come in useful.

So any suggestions please, where from and approx price. Is it worth buying a 3-stage charger. I assume that I want some sort of smart charger......................thanks

suggest you look for a permanently connected 'trickle' charger, solar perhaps, rather then cycle your battery through ups and downs with a conventional charger. every discharge builds up oxides on the plates and accumulates 'debris' on the bottom of your battery, eventually shorting out the plates.

maintaining a permanent charge is much more healthy for lead / acid's than cycling.

If you go for a solar charger make sure it has a blocking diode to prevent power from the battery going back to the solar charger at night.

Be sure you get a maintenance charger versus trickle charger if leaving the charger hooked to the battery all the time.

http://www.pulsetech.net/assets/Misc/Trickle-vs-Maintenance-Chargers.pdf

To trickle charge or maintain charge your 12‐ Volt lead‐acid batteries with a smart charger is a decision that might affect the health and life cycle of your batteries. While both are designed to slowly emit low‐voltage charges to your vehicle battery, restoring the battery to a full charge status over several hours, the critical difference lies in the chargers’ ability to automatically shut off the charge current and not overcharge batteries, which can lead to overheating and serious damage. Another important difference is the ability of some maintenance chargers to desulfate and clean battery plates, restoring them to normal operation and extending battery life. Trickle chargers are designed to maintain a charge equal to the self‐discharge rate of the battery ( 2.23 to 2.25 volts per cell) and it is recommended they be disconnected from the battery to prevent the possibility of overcharging. Leaving an unattended trickle charger on for too long might lead to overheating, causing the battery to boil the electrolyte. The outcome would be a dead battery or a worse case scenario— a possible fire/explosion. A maintenance charger (also called a float or smart charger), however, is a true plug‐ and‐play product that takes the human error element out of the battery charging function. Maintenance chargers can be left connected to the battery indefinitely without risk of damage to the battery. Battery maintenance chargers completely shut off the charge current output to allow the battery to settle, and when the battery’s voltage drops to a certain point, the charger will automatically turn back on and top off the battery. This is safer than a trickle charger.

I use maintenance chargers on vehicles garaged in the UK and always have full charge when I need it. Car batteries kept in good condition are expected to last for up to 5 years before starting to degenerate but using maintenance chargers I normally get up to 9 years. A good investment.

Whatever charger you go for it must be designed for sealed batteries. You must not use the old high Amperage charger that you may have used on a wet cell battery. Doing so will probably wreck it or drastically shorten its life. The CTEK battery tender already mentioned which is available from Lazada amongst many others will help extend the working life of your battery. This is just one amongst many brands designed for sealed MF batteries.

In Thailand, maintenance chargers may only extend a car battery's life from 2-3 years to 3-4 years due to the heat.

Available in Thailand around 4.000 THB in multiple online shops.

It's safe, easy, compact and Swedish quality...

I've been looking at car battery chargers as well. Not many choices available here. Read the reviews on the CTEK charger online, swedish brand with lots of good reviews by car magazines and online, looks like its a great charger for the price. The model CTEK MX5 is just slightly more expensive than overseas ($100 / 3500 baht) compare to 4000 baht here comes with 5 year warranty and free delivery. They also have a basic model charges at slower rate and less type of batteries model CTEK XS 0.8 going for 2500 baht.

Found the authorize dealer website http://www.jumpandcharge.com/en the english site doesn't work though, the seller speaks fluent english.

Looked at other brands and on lazada, they are mostly oem chinese junk. I will probably purchase one of the CTEK in the coming weeks. Another plus I found out is the size of the charger.

If OP doesn't use much perhaps the cheaper model 2500 baht will do.

Mike ... regarding your comment about many chargers being "oem Chinese junk"

 

CTEK is indeed a Swedish company, and their chargers do seem to enjoy good reviews, however, all CTEK chargers are manufactured in Shenzhen China, then shipped to Belgium for distribution.  Sorry about that. You've purchased a Chinese made charger.

I am using VICTRON chargers for my batteries. Dutch product, available in LoS. Very very good charger if I may say so.

Comes in IP65 or IP67 versions.

Foer the de-sulph thing I am using a pulse generator from a Stirling, UK product. Happy with this combination.
