battery going flat, what charger to buy?

Hi, having reassembled my engine it so nearly fired up today but the more i tried the less and less power was left in the battery to the point it would fully turn it now. So I'm guessing I'll need to charge it up, question being, I imagine a normal car battery charger won't do the job?

The battery is an ODYSSEY PC545 and here is the blurb:

Pulse (5-second) Hot Cranking Amps (PHCA) 460
Cold Cranking Amps (CCA) 150
20Hr Nominal Capacity (Ah) 13
Reserve Capacity Minutes 18

What should I be looking to buy and any suggestions, thanks!

Hi there,

yeah I ended up just using a car charger. Gave it a quick 30 minute charge and it started easily.
One of the reasons it wouldn't start last night is it's been sitting cold for 2 weeks (the engine) and I'd forgotten to choke it.
Happy now with engine so have now taken battery out overnight to give it full charge
thanks for the reply

If the battery is servicable, check the electrolyte levels. You can top up with distilled water. I normally put my own battery on a trickle charge for 2-3 hours before taking the boat out as it can be a few weeks between outings.

There's nothing more frustrating than a low-charge battery, which is completely preventable. Halford's range of battery chargers are as good as any in my opinion.

Yes do a visual-check of electrolyte LEVELs and Hydrometer reading of each cell before charging, provided the fluid is above all plates. If not, used ONLY Distilled Water to top off cells requiring it. Charge using a "Smart Charger" as they will not over/under charge your battery. Then Check the reading of each cell with a Hydrometer if you first added distilled water before charging. Good Luck.
